hdtune test will not damage the hard disk, because the hard disk test is to read and write the hard disk blocks, which is the same as reading and writing the hard disk in ordinary times, and will not cause damage to the hard disk; hdtune is a hard disk detection tool , its main functions include hard disk transfer rate detection, health status detection, temperature detection, disk surface scanning access time, and CPU usage.
The operating environment of this tutorial: Windows 10 system, HD Tune Pro version 5.75, Dell G3 computer.
Will hdtune test damage the hard drive?
No, the hard disk test is to read and write the hard disk blocks. This is the same as reading and writing the hard disk in ordinary times. It is just comprehensive. There is no need to worry about causing damage to the hard disk.
Hard disk detection tool (HD Tune Pro) is a compact and easy-to-use hard disk tool software. Its main functions include hard disk transfer rate detection, health status detection, temperature detection and disk surface scanning access time and CPU usage. Rate. In addition, it can also detect the hard drive’s firmware version, serial number, capacity, cache size, and current Ultra DMA mode. Although these functions are also available in other software, what is commendable is that this software integrates all these functions into one, and is very compact and fast. More importantly, it is free software and can be used freely.
Software functions
1. Benchmark
The "Benchmark" item is to test the transmission rate of the hard disk. The average transmission rate of the hard disk is probably more than 100 , reflecting the hard disk read and write speed.
2. Information
The "Information" item is to view the basic information of the hard disk, including supported features, firmware version, hard disk capacity, sector size and other basic information.
3. Health
If an item is yellow, it means there is a problem. If it is red, the problem is more serious.
Partial numerical description (from Tieba, for reference only):
01) Underlying data reading error rate: If this "data" value is greater than 0, it indicates that there has been a problem with reading and writing. The threshold cannot be exceeded. If the worst value is very low, it indicates that the hard disk may have bad sectors.
03) The time required for the motor to reach the standard speed: The "current, worst" value of this item is larger, indicating that the hard disk starts slowly.
04) Motor restart/stop count: The "data" value indicates the number of hard drive restarts.
05) Number of remapped sectors: The "value" of this item indicates that when the hard disk finds a bad sector when reading a certain sector, it maps the data in the bad sector to other free sectors. This A value of 0 is best, indicating that there are no bad areas.
07) Seek error rate: The error rate of my hard disk is very high, exceeding the threshold of 30, and the performance is really not good.
09) Cumulative power-on time: From the "data" of this item, it can be seen that the hard disk is still used when it is new. The data value of the new disk should be within 20.
0A) The motor rotation reaches the standard speed and the retry count: The data value of this item should be less than the threshold. If the value is too large, it indicates that the hard disk has a mechanical failure.
0C) Power cycle count: Indicates the number of switching times of the hard disk.
BB) Uncorrectable error reported: "data value" is preferably 0.
C0) Magnet head retraction count after power outage: Mainly caused by a sudden power outage during hard disk operation. This data will cause changes in other values.
C1 head extension count: Generally, the maximum C1 value of a hard disk is only 30w-60W times. If the C1 value exceeds 20,000, then you should pay attention.
C4 sector operation count: The smaller the data value, the better. A large value indicates that reading and writing errors often occur.
C5 The number of sectors currently to be mapped: the number of sectors that are bad but have not yet been mapped. The smaller the data value, the better.
C6 Uncorrectable sector count: The smaller the data, the better, may be caused by physical damage to the sector.
C7 interface communication error: DMA transmission error
4. File benchmark
It is mainly the access speed to the stored file.
5. Error scan Error scan
Scan the hard disk for bad sectors. The green dots are normal and the red dots are bad sectors. Repair them in time.
6. Random Access
Check the hard drive's time and speed required for non-random file access.
