Description

Method and system for checking whether the system environment of a data storage device is abnormal

The present invention relates to a method and system for checking whether the system environment of a data storage device is abnormal, and in particular, to a method and system for synchronously checking whether the system environment of a data storage device or the data storage block itself is abnormal when a control unit such as a controller or a processing unit such as a CPU in various existing electronic devices executes various operation instructions.

In the related technical fields of data execution, processing and storage in various existing electronic devices, when the system environment itself is abnormal and causes an abnormal operation state, it is possible that the subsequent hardware module will make an incorrect judgment. Because in the existing technology, the subsequent hardware module cannot distinguish the real cause of the abnormal operation state, and may therefore perform incorrect abnormal processing.

Furthermore, in the prior art, when a read data error or a write data error occurs during data execution, processing, and storage, other normal data in the data storage block will be moved to a normal data storage block. However, if the real problem is an abnormal system environment rather than a real abnormality in the data storage device, frequent block reading, writing, or moving will increase the consumption of block life and write amplification.

In addition, abnormal system environment may cause errors in the operation command status, and even cause the software to mistakenly judge that the data storage block is no longer usable. Furthermore, if an external hardware detection circuit is used to check the block or system environment, it will increase the overall marketing cost.

Therefore, in order to overcome the aforementioned problems, the present invention is developed.

In order to overcome the technical problems that the hardware module cannot distinguish the real cause of the abnormal operation state and may perform erroneous abnormal processing, increase the consumption of block life and write amplification due to non-real abnormality of the data storage device, and cause the software to misjudge that the block cannot be used again due to an error in the operation instruction state, and add a hardware detection circuit to check the block or system environment, which will increase the overall marketing cost, the present invention provides a method and system that can check whether the system environment of the data storage device is abnormal. Using the method and system of the present invention, a system for detecting whether the system environment is abnormal or a method for detecting whether the system environment is abnormal can be added to the data storage device in various existing electronic devices. A reference block is pre-configured in the data storage device. When the operation command is executed, for example, the status of the operation command is confirmed by reading the status (Read Status). When an error is reported, the reference block is read. If the data is read incorrectly, it can be known that the error is caused by an abnormality in the system environment, not the data storage device. The present invention can be achieved only in software (firmware) mode without adding additional hardware costs. The method and system of the present invention can immediately detect abnormalities in the system environment or blocks, and make corresponding processing to ensure that the system is normal.

To achieve the aforementioned purpose, the present invention provides a method for checking whether the system environment of a data storage device is abnormal, comprising: Step A: receiving an operation instruction, wherein the operation instruction includes at least one of the steps of reading, writing and erasing a block in the data storage device; Step B: executing the operation instruction, and confirming whether the instruction execution status corresponding to at least one of the steps of reading, writing and erasing data in the block in the data storage device is correct; if the instruction execution status is correct, then the entire step is terminated; if the instruction execution status is incorrect, then step C is performed; Wherein the step C includes checking whether the system environment is abnormal; if the checking result is that the system environment is abnormal, then proceeding to step D; if the checking result is that the system environment is normal, then proceeding to step d; Wherein the step D includes: marking the system abnormality; Wherein the step d includes: checking whether the block itself of at least one of the read, written and erased is abnormal.

In practice, step C further includes: reading a preset comparison block in the data storage device; if the reading result is that the instruction execution status is abnormal, then performing step D; if the reading result is that the instruction execution status is normal, then performing step d.

In practice, step C further includes: checking whether the system environment is abnormal; if the system environment is abnormal, performing step C at least once again after a certain period of time.

In practice, the step d further includes: checking whether the block of at least one of the blocks read, written and erased is abnormal. If the block is abnormal, an abnormal flag is set for the block.

The present invention also provides a system for checking whether the system environment of a data storage device is abnormal, which includes: a data storage block and a control unit. The data storage block includes a block; and the control unit includes: a receiving unit, a processing unit and a checking unit. The receiving unit is used to receive an operation instruction, wherein the operation instruction includes at least one step of reading, writing and erasing the block. The processing unit is used to execute the operation instruction and confirm whether the instruction execution status corresponding to the steps of reading, writing, and erasing data on the block is correct; if the instruction execution status is correct, the entire step is terminated; if the instruction execution status is incorrect, the checking unit is used to check whether the system environment is abnormal; if the check result is that the system environment is abnormal, the system is marked as abnormal; if the check result is that the system environment is normal, the checking unit is used to check whether the block itself of at least one of the read, written, and erased is abnormal.

During implementation, the checking unit is further used to check whether the system environment is abnormal. If the system environment is abnormal, the system environment is checked again at least once after a time interval to determine whether the system environment is abnormal. If the checking result is that the system environment is abnormal, the system is marked as abnormal. If the checking result is that the system environment is normal, the checking unit is used to check whether at least one of the blocks being read, written, and erased is abnormal.

In implementation, the data storage block further includes a default comparison block; wherein the processing unit is further configured to read the default comparison block; if the reading result is that the instruction execution status is abnormal, the system is marked as abnormal; if the reading result is that the instruction execution status is normal, the checking unit is used to check whether at least one of the blocks read, written and erased is abnormal.

During implementation, the processing unit is used to read the preset comparison block at least once. If the reading result is that the instruction execution status is abnormal, the system is marked as abnormal; if the reading result is that the instruction execution status is normal, the checking unit is used to check whether at least one of the blocks read, written and erased is abnormal.

During implementation, the checking unit is further used to check whether the block itself of at least one of the read, written and erased is abnormal. If the block itself is abnormal, the block will be marked as abnormal.

During implementation, the processing unit is further configured to execute a processing procedure for marking the block as abnormal.

In order to further understand the present invention, the following preferred embodiments are given, and the specific structure and effects of the present invention are described in detail with reference to the drawings and figure numbers.

Please refer to FIG. 1. The present invention provides a system for checking whether the system environment of a data storage device is abnormal, which includes a control unit 11 and a data storage block 12. The control unit of the present invention can be a software (firmware), hardware or logic circuit structure, all of which are within the scope of the present invention. Furthermore, the data storage block 12 includes a block 121. The control unit 11 includes: a receiving unit 111, a processing unit 112 and a checking unit 113. The receiving unit 111 is used to receive an operation instruction, wherein the operation instruction includes the step of reading, writing and erasing the block. The processing unit 112 is used to execute the operation instruction and confirm whether the instruction execution status corresponding to the read, write, and data erase of the block is correct. If the instruction execution status is correct, the whole step is terminated; if the instruction execution status is incorrect, the checking unit 113 checks whether the system environment is abnormal; if the check result is that the system environment is abnormal, the system is marked as abnormal; if the check result is that the system environment is normal, the checking unit 113 checks whether the block itself of at least one of the read, write, and erase is abnormal.

Again, please continue to refer to FIG. 1 , the checking unit 113 is further used to check whether the system environment is abnormal. If the system environment is abnormal, then after a time interval, the system environment is checked again to see if it is abnormal at least once. If the checking result is that the system environment is abnormal, then the system is marked as abnormal. If the checking result is that the instruction execution status is normal, then the checking unit checks whether at least one of the blocks being read, written and erased is abnormal. The data storage block 12 further includes a default comparison block 122; wherein the processing unit 112 is further provided for reading the default comparison block 122; if the reading result is that the instruction execution status is abnormal, the system is marked as abnormal; if the reading result is that the instruction execution status is normal, the checking unit 113 checks whether the block itself of at least one of the read, written and erased is abnormal. The processing unit 112 is further configured to read the preset reference block at least once. If the reading result is that the instruction execution state is abnormal, the system is marked as abnormal. If the reading result is that the instruction execution state is normal, the checking unit 113 is used to check whether the block read, written and erased is abnormal. The processing unit 112 is further configured to execute a processing procedure for system environment abnormality. The checking unit 113 is further configured to check whether the block read, written and erased is abnormal. If the block is abnormal, the block is marked as abnormal, for example, an abnormal flag is set for the block. The processing unit 112 is further configured to execute a block abnormality processing procedure.

The present invention also provides a method for checking whether the system environment of a data storage device is abnormal, comprising: Step A: receiving an operation instruction, wherein the operation instruction includes at least one of the steps of reading, writing and erasing a block in the data storage device; Step B: executing the operation instruction, and confirming whether the instruction execution status corresponding to the steps of reading, writing and erasing data in the block in the data storage device is correct; if the instruction execution status is correct, then the entire step is terminated; if the instruction execution status is incorrect, then step C is performed; Wherein the step C includes checking whether the system environment is abnormal; if the checking result is that the system environment is abnormal, then proceeding to step D; if the checking result is that the system environment is normal, then proceeding to step d; Wherein the step D includes: marking the system abnormality; Wherein the step d includes: checking whether the block itself of at least one of the read, written and erased is abnormal.

The method and system of the present invention will be described in detail below. First, please refer to Figure 2. In step A, an operation instruction is received, wherein the operation instruction includes at least one of the steps of reading, writing and erasing a block in a data storage device. The operation instruction may be, for example, listing all files and paths, listing hidden directories, moving files, adding folder data import, data export, etc., and the operation instruction includes at least one of the steps of reading, writing and erasing a block in a data storage device. The data storage device of the present invention can be a data storage device built in various machines for various industrial and personal use today. Then, in step B, the operation command is executed to execute the aforementioned procedures, such as listing all files and paths, listing hidden directories, moving files, adding folders, data importing, data exporting, etc., and confirming whether the command execution status corresponding to the steps of reading, writing, and erasing the blocks in the data storage device is correct; if the command execution status is returned to be correct, the entire step is terminated, which indicates that the command execution of the data storage device is operating normally. If the command execution status is incorrect, that is, at least one program in the command execution status returned by the system cannot be executed normally, then step C is performed. When the system environment itself is abnormal and causes the read status instruction to return an abnormality, the system of the present invention will enable the subsequent software module to determine the source of the error. Because, as mentioned above, in the prior art, the subsequent hardware module cannot distinguish the actual cause of the read status abnormality, and may therefore perform incorrect exception processing. Therefore, in step C of the present invention, the system environment is first checked to see if it is abnormal. The steps of checking whether the system environment is abnormal include: for example, using a simulator to predict whether the reading and writing speeds have slowed down; the system environment of cluster training in machine learning training meets the critical value conditions; detecting applications running in the operating system environment; detecting the network system environment such as the temperature of the wiring entry and wiring exit; detecting the power output of the system's RTC battery, accessing certain memory locations that are not allowed to be accessed, or accessing certain memory locations in an unauthorized manner; and detecting a storage segment error when it is detected that a non-existent block is accessed and a memory segment with no access permission is accessed. If the check result is that the system environment is abnormal, then proceed to step D; if the check result is that the instruction execution status is normal, then proceed to step d. That is, if the check result is that the instruction execution status is normal, then check whether the block itself is abnormal and causes the instruction execution status to be abnormal. In addition, the step D includes marking the system abnormality so that the entire system performs subsequent checks on the program corresponding to the abnormal flag. The step d includes checking whether the block itself of at least one of the read, written and erased is abnormal.

Furthermore, in another embodiment, please refer to FIG. 3 , the step of checking whether the system environment is abnormal in step C includes: reading the preset reference block 122 in the data storage device; if the reading result is that the instruction execution status is abnormal, then the aforementioned step D is performed to mark the system abnormality, so that the entire system can perform subsequent processing for the situation marked as abnormal system, for example, by setting an abnormal flag. If the reading result is that the instruction execution status is normal, then the aforementioned step d is performed to check whether the block itself of at least one of the read, written and erased is abnormal, so as to confirm whether the block itself is abnormal. In another embodiment, the aforementioned step C further includes: reading the default comparison block 122 in the data storage device; if the reading result is that the instruction execution status is abnormal, then after a time interval, the aforementioned step C is performed again at least once, that is, reading the default comparison block 122 in the data storage device, if the reading result is that the instruction execution status is abnormal, then performing the aforementioned step D, marking the system abnormality, so that the entire system performs subsequent checks on this abnormal flag; if the reading result is that the instruction execution status is normal, then performing the aforementioned step d, checking whether the block itself of at least one of the read, written and erased is abnormal, so as to confirm whether the block itself is abnormal. Therefore, the method and system of the present invention pre-configures a reference group block in the data storage device. When an error occurs in the response of the execution status of an operation command, the reference group block is read. By reading the data to determine whether the execution status of the relevant command is abnormal, it can be distinguished whether the error is caused by the abnormality of the system environment as mentioned above, or whether the block of the data storage device itself is truly abnormal. In another embodiment, for example, when checking whether the default reference block 122 in the read data storage device is abnormal in step C, if the reading result is that the instruction execution status is abnormal, then the aforementioned step C is performed again after a time interval, for example, 8 times, and if the reading result is that the instruction execution status is abnormal once, then it is determined that the instruction execution status is abnormal; or, in another embodiment, if the reading result is that the instruction execution status has an abnormal number of times greater than the normal number, for example, 5 times out of 8 are abnormal and 3 times are normal, then it is determined that the instruction execution status is abnormal. Alternatively, in another embodiment, if the read result is that the instruction execution status has too high anomalies, for example, if the instruction execution status of each read result is abnormal, it is necessary to check whether the default comparison block 122 itself is abnormal.

Furthermore, in another embodiment, please refer to FIG. 4 , step C further includes: checking whether the system environment is abnormal. If the system environment is abnormal, then after a time interval, the aforementioned step C is performed at least once again. If the reading result is that the system environment is abnormal, then the step D is performed; if the reading result is that the system environment is normal, then the step d is performed. This procedure is to ensure that the system environment is indeed abnormal, rather than the execution error message returned due to a defect in the execution instruction itself or due to other factors. In this embodiment, when checking whether the system environment is abnormal in step C, if the system environment is abnormal, then after a time interval, the aforementioned step C is performed at least once, for example, 1 to 3 times, 4 to 6 times or 8 to 10 times, etc., all within the scope of the present invention. If the reading result is that the system environment is abnormal, then the step D is performed; if the reading result is that the system environment is normal, then the step d is performed. In this embodiment, for example, when checking whether the system environment is abnormal in step C, if the system environment is abnormal, then after a time interval, the aforementioned step C is performed again, for example, 8 times. If the reading result is that the instruction execution status has an abnormality, then the step D is performed; if the reading result is that the system environment is normal, then the step d is performed.

Furthermore, in another embodiment, please refer to FIG. 2 to FIG. 4, after step D, step E is further included. In step E, a system environment abnormality processing procedure is executed. According to the aforementioned example, if the simulator predicts whether the read and write speed of specific software and hardware has become slow, the system environment abnormality processing procedure is executed to adjust the software and hardware program that slows down the read and write speed. If the system environment of cluster training in machine learning training does not meet the critical value condition, the system environment abnormality processing procedure is executed as part of suspending cluster training. If an application running in the operating system environment is detected to be abnormal, the system environment abnormality processing procedure is to close or restart the abnormal application. If the network system environment such as the temperature of the wiring inlet and wiring outlet is detected to be abnormal, the system environment abnormality processing procedure is to cool down the wiring inlet and wiring outlet or suspend data transmission. If the power output of the RTC battery of the system is detected to be abnormal, the system environment abnormality processing procedure is to restart the power output of the RTC battery to confirm the abnormal situation. If an attempt is made to read data outside the program address space or write to a read-only memory segment, resulting in a memory block read error, the system environment exception handling procedure is executed to skip the read-only memory segment, etc.

Furthermore, in another embodiment, please continue to refer to FIG. 2 to FIG. 4, in step d, it further includes: checking whether the block itself of at least one of the read, written and erased is abnormal, and if the block itself is abnormal, setting an abnormal mark for the block. Taking a flash memory card, a solid state hard drive (SSD), and an embedded flash memory storage device as an example, the abnormality of the block itself will cause an abnormal memory page error and a storage block error. The abnormality of the block itself may also occur in the memory page, such as an overflow in the same memory page but not overwritten by a normal process. In addition, context switching, hardware paging errors, and interrupts can also cause block exceptions. If a block is found to be abnormal, an abnormal flag is set for the block so that the abnormal block will not be read, written, or erased in subsequent steps.

Furthermore, in another embodiment, please continue to refer to FIG. 2 to FIG. 4 , after step d, step e is further included. In step e, a block abnormality processing procedure is executed. As mentioned above, if the block abnormality is a block abnormality that will cause an abnormal memory page error and a storage segment error, a block abnormality that occurs in a memory page such as overflow, context switching, hardware paging error or interruption in the same memory page but not overwritten by a normal program, etc., then the block abnormality processing procedure is executed for the above-mentioned situations respectively.

Therefore, the present invention has the following advantages: 1.         The method and system of the present invention can be set in various existing electronic devices, and can be achieved only by software (firmware) mode, without adding additional hardware costs, and can immediately detect abnormalities in the system environment or blocks, and make corresponding processing to ensure the normal operation of various electronic systems. 2.         The method and system of the present invention pre-configures a reference group block in the data storage device. When an error occurs in the response of the execution status of the operation command, the reference group block is read. If the data reading is still wrong, it can be known that the error is caused by the abnormality of the system environment, not the real abnormality of the data storage device. 3.         Under the protection of the method and system of the present invention, the system environment anomalies of various existing electronic devices can be discovered in real time, and frequent block reading, writing or moving can be effectively avoided, thereby greatly improving the life of the data storage device.

The above are specific embodiments of the present invention and the technical means used. Many changes and modifications can be derived based on the disclosure or teaching of this article, which can still be regarded as equivalent changes made to the concept of the present invention. The effects produced still do not exceed the essential spirit covered by the description and drawings, and should be regarded as within the technical scope of the present invention.

In summary, according to the contents disclosed above, the present invention can achieve the expected purpose of the invention, and provide a method and system for checking whether the system environment of a data storage device is abnormal. When an error occurs in the status reply of an operation command, the reference group block is read. If the data is read incorrectly, it can be known that the error is caused by the abnormality of the system environment, rather than the real abnormality of the data storage device. The invention has great value for industrial use, and a patent application for the invention is filed in accordance with the law.
