[0060] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0061] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0062] Based on the above objectives, a first aspect of the present invention provides a hard disk firmware debugging method. In such... Figure 1 In the illustrated embodiment, the method includes the following steps:

[0063] S10. Determine the first average erase / write wear rate of the first hard disk;

[0064] S20. Use an endurance test script to test the first hard disk, and calculate the number of blocks that need to be modified and the second user capacity based on the test results.

[0065] S30. Modify the firmware of the first hard disk based on the second user capacity and the number of blocks;

[0066] S40. After the firmware modification is completed, the endurance test script is used to test the second hard drive after the firmware modification, and the second average erase and write wear rate of the second hard drive during the test is obtained.

[0067] S50. Adjust the second user capacity and / or the number of blocks based on the difference between the second average erase / write wear rate and the first average erase / write wear rate so that the second average erase / write wear rate meets the requirements.

[0068] Specifically, in step S10, the first average erase / write wear rate of the first hard disk is determined. The hard disk can be a solid-state drive. Based on the NAND lifespan and Ea characteristics of the solid-state drive, the test temperature and test duration are determined, and then the average erase / write wear rate of the solid-state drive at normal capacity is determined, i.e., the first average erase / write wear rate.

[0069] In step S20, an endurance test script is used to test the normal capacity disk, i.e., the first hard disk, and the number of blocks that need to be modified and the second user capacity are calculated based on the test results.

[0070] In step S30, the firmware of the first hard disk is modified based on the second user capacity and the number of blocks, thereby adjusting the capacity of the normal capacity disk to a small capacity disk, i.e., the second hard disk.

[0071] In steps S40 and S50, after the firmware modification is completed, an endurance test script is used to test the small-capacity disk and obtain the second average erase / write wear rate of the second hard drive during the test. It is observed whether the second average erase / write wear rate reaches the first average erase / write wear rate. If there is a difference, the second user capacity and / or the number of blocks are adjusted so that the second average erase / write wear rate reaches the first average erase / write wear rate. This ensures that after the hard drive capacity is adjusted, it can still maintain some characteristics of the normal capacity.

[0072] The above method can efficiently adjust the firmware of the hard drive used for testing, and retain some characteristics of the original capacity hard drive while reducing the hard drive capacity.

[0073] Furthermore, the adjusted firmware parameters can be used for tests related to hard drive security and stability, such as endurance testing, thereby improving test accuracy and efficiency.

[0074] In some implementations, step S20 includes:

[0075] S21. Use an endurance test script to test the first hard disk and obtain the average write bandwidth and write amplification of the first hard disk;

[0076] S22. Calculate the second physical capacity based on the average write bandwidth, the write amplification, and the first average erase / write wear rate;

[0077] S23. Calculate the number of blocks based on the second physical capacity and the block capacity of the first hard disk;

[0078] S24. Calculate the second user capacity based on the reserved space of the first hard disk and the second physical capacity.

[0079] The above method can be used to obtain a second user capacity for adjusting the hard drive firmware.

[0080] In some implementations, step S21 includes:

[0081] The first hard drive was tested using an endurance test script to obtain its average write bandwidth. Write amplification was calculated based on the increase in host write volume and the increase in garbage collection volume during the test. Write amplification = (increase in host write volume + increase in garbage collection volume) / increase in host write volume.

[0082] Step S22 includes:

[0083] The amount of data written to the first hard disk per unit time is calculated based on the average write bandwidth.

[0084] The second physical capacity is calculated based on the write amount, the write amplification, and the first average erase / write wear rate. The second physical capacity = write amount × write amplification / first average erase / write wear rate.

[0085] Step S24 includes:

[0086] The reserved space is calculated based on the first physical capacity and the first user capacity of the first hard disk;

[0087] The second user capacity is calculated based on the reserved space and the second physical capacity. The second user capacity = the first physical capacity / (1 + reserved space).

[0088] In some implementations, step S50 may include the following steps:

[0089] S51. Determine whether the second average erase / write wear rate reaches the first average erase / write wear rate;

[0090] S52. If the second average erase / write wear rate does not reach the first average erase / write wear rate, then adjust the second user capacity and / or the number of blocks, and return to the step of modifying the firmware of the first hard disk based on the second user capacity and the number of blocks;

[0091] S53. If the second average erase / write wear rate reaches the first average erase / write wear rate, then the method ends.

[0092] In some implementations, step S50 may further include the following steps:

[0093] S55. Determine whether the second average erase / write wear rate reaches the first average erase / write wear rate and does not exceed the threshold, wherein the threshold can be set to (1+20%) of the first average erase / write wear rate, but is not limited thereto;

[0094] S56. If the second average erase / write wear rate does not reach the first average erase / write wear rate or reaches the first average erase / write wear rate and exceeds the threshold, then adjust the second user capacity and / or the number of blocks, and return to the step of modifying the firmware of the first hard disk based on the second user capacity and the number of blocks;

[0095] S57. If the second average erase / write wear rate reaches the first average erase / write wear rate but does not exceed the threshold, then the method ends.

[0096] In some implementations, the method further includes:

[0097] During the testing of the second hard drive, the actual erase and write wear rate was monitored;

[0098] When the actual erase / write wear rate reaches the first average erase / write wear rate, the data writing operation during the test is stopped.

[0099] In some implementations, the step of calculating the second physical capacity based on the write amount, the write amplification, and the first average erase / write wear rate includes:

[0100] The second physical capacity is calculated based on the physical capacity calculation formula, the write amount, the write amplification, and the first average erase / write wear rate, wherein the physical capacity calculation formula is:

[0101] Second physical capacity = Write amount × Write amplification / First average erase / write wear rate.

[0102] In some implementations, the step of calculating write amplification based on the host write increment and garbage collection increment during the test includes:

[0103] The write amplification is calculated based on the write amplification formula, the host write increment, and the garbage collection increment, wherein the write amplification formula is:

[0104] Write amplification = (Increment in host writes + Increment in garbage collection) / Increment in host writes;

[0105] The step of calculating the reserved space based on the first physical capacity and the first user capacity of the first hard disk includes:

[0106] The reserved space is calculated based on the reserved space calculation formula, the first physical capacity, and the first user capacity, wherein the reserved space calculation formula is:

[0107] Reserved space = First physical capacity / First user capacity - 1;

[0108] The step of calculating the second user capacity based on the reserved space and the second physical capacity includes:

[0109] The second user capacity is calculated based on the user capacity calculation formula, the reserved space, and the second physical capacity, wherein the user capacity calculation formula is:

[0110] Second user capacity = First physical capacity / (1 + reserved space).

[0111] The following describes the concept of the present invention in conjunction with a specific hard drive firmware debugging process. It should be understood that the embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0112] like Figure 2 As shown, the specific hard drive firmware debugging process is as follows:

[0113] S1. Based on the NAND lifespan and Ea characteristics, determine the test temperature and test duration, and then determine the average PE (Program & Erase) wear rate S per hour. PE (i.e., the first average erase / write wear rate in the embodiments of the present invention), the following describes S PE The calculation process is illustrated with an example:

[0114] When the NAND lifespan is 10000PE and Ea = 1.0, and the NAND is tested at a temperature of 80.8℃, it needs to be tested for 1000 hours. Then SPE = 10000PE / 1000h = 10PE / h, which means that it takes one hour to wear down 10PE. After testing for 1000 hours, the NAND can be worn down to the end of its lifespan.

[0115] S2. For a normal capacity disk under steady-state conditions, the average write bandwidth (BW) is measured using the Endurance test script. The write amplification (WA) is calculated based on the increase in host write volume and the increase in GC (garbage collection) write volume. The formula for calculating write amplification is:

[0116] WA = (increment of host_write_cnt + increment of gc_write_cnt) / increment of host_write_cnt;

[0117] Here, host_write_cnt represents the amount of data written to the host, and gc_write_cnt represents the amount of data written during garbage collection.

[0118] S3. Calculate the reserved space OP based on the normal capacity disk. OP = physical capacity / user capacity - 1.

[0119] S4. Calculate the write count per hour based on the write bandwidth BW.

[0120] S5. Calculate the average write volume per 1PE increase, which is the physical capacity C of the small-capacity disk after adjusting the normal capacity disk to a small-capacity disk (i.e., the second hard disk in this embodiment). phy =write_count_per_hour*WA / S PE Then, based on the capacity of each block, the number of blocks is calculated.

[0121] S6, Physical capacity C via OP and small capacity disk phy To calculate the user capacity C user C user =C phy / (OP+1).

[0122] S7. This initially determined the user capacity C of the small-capacity disk. user After modifying the hard drive firmware and determining the number of blocks, the Endurance test script was used to conduct tests and observe the actual average PE wear rate S. PE_real Can it reach S? PE If there is a slight difference, then adjust the user capacity C. user Fine-tune the number of blocks until the PE wear rate condition is met.

[0123] S8. To further ensure the actual PE wear rate in the test, and to control the write volume of the Endurance test script, when the PE growth reaches S within one hour... PE If no data is written, only read-only operations are performed. By controlling the PE growth of the test script, the wear growth of the PE during the test can be effectively guaranteed to be relatively uniform within a unit of time.

[0124] The above scheme obtains the user capacity and number of blocks of the small capacity disk through the actual test results and calculations of the normal capacity disk. After testing the small capacity disk, it is fine-tuned until the test conditions are met. This can efficiently adjust the firmware of the hard drive used for testing, and maintain some characteristics of the normal capacity hard drive while reducing the hard drive capacity.

[0125] Furthermore, the adjusted firmware parameters can be used for tests related to hard drive security and stability, such as endurance testing, thereby improving test accuracy and efficiency.
