VCR full name victoria, it is Windows bad track scanning and simple bad track repair tool, it can read and write to the hard disk test, the following is its Smart ((Self-Monitoring Analysis And Reporting Technology), the full name is "self-detection analysis and reporting technology" important part of the description

(note: VCR software can correctly detect the SMART value of SATA disks, but it cannot detect correct data for SAS disks. VCR is mostly used for reading and writing tests of these two types of hard disks.)

Usually, when we check whether the hard drive is good or bad, we will look at several items in the picture.

1:5 reassign the number of sectors (what we call the number of G tables, that is, the number of bad tables) the original value of the normal hard disk is 0, if these values are not 0, the hard disk will be unstable, and the hard disk needs to be repaired or replaced.

2:9 power up cumulative time power on time

Of course, the new hard drive should be close to 0, but different hard drives have different counting units, ranging from hours to minutes, seconds, or even 30 seconds, which is defined by the disk manufacturer. If the original value in the picture is "3634", it means that the power-on time reaches 3634 hours.

12 start / stop total power on

A new hard drive, both of which will be 0.

3Rank 197 this value is 0 when the number of sectors to be mapped is normal, and this value is the number of sectors waiting to be written to the G table. If the number is not 0, the hard disk will be unstable. It should be dealt with as soon as possible.

198 cannot be corrected offline when the number of sectors is normal, this value is 0, which is the number of errors that cannot be corrected when reading sectors. If the value is long, it indicates that there is a problem with the hard disk and some sectors cannot be read.
