This information is also shown graphically in the left window.We are digital librarians. This mode is recommended to experienced users only, because using it in the wrong way can damage the disk and cause a data loss.Īs you can see, Victoria analyses the drive and shows the number of sectors in categories depending on their response time. In the Erase mode, the program tries to write data into the damaged sector and use it further.With the help of Restore mode, you can try restoring the sectors damaged at the software level.In the Remap (reassign) mode, the program replaces damaged or broken sectors with good sectors from the drive’s reserved area.At the moment, we started testing in this mode. In the Ignore mode, the program analyses and represents information.Bad sectors can be hidden by replacing them with good sectors from the drive’s reserved area.īefore the test begins, choose of the options: Ignore, Remap, Erase, Restore. This problem can be caused by both physical wear of the hard drive and wrong use.

The longer time it takes for a sector to respond, the more likely it is to fail. The principle is like this: the drive is divided into sectors having similar length, and the program sends a request to every sector. For a simple test, leave everything as it is. You can also choose what the program does after the test (see the End of Test pop-up menu), choose a test type and so on. This is where you can set the beginning and the end of the tested area, which is by default set to cover the entire drive: these are fields Start LBA – End LBA. Now let us move to the most important tab Tests which actually checks the disk for bad sectors. The disk we are testing is knowingly in a good condition, and it is only used as an example to illustrate main features that Victoria has to offer. If values in these attributes were higher than zero, or if they were not corrected with hardware means in time, it would indicate there are problems with the drive.

196 – the number of reallocation operations.

187 – the number of sectors to be reallocated in the future.

5 – the number of sectors reallocated by the hard drive to a reserved area.

195 – the number of errors that have been fixed with hardware means.

There are many of them in the screenshot, but it’s not critical because this number coincides with the attribute However, the following items will be most important for quick evaluation of a disk condition: There are many SMART attributes, and all of them are important. It contains real values directly telling you about the disk health. RAW is the most important indicator for evaluation of the drive condition. Tresh is the value that an attribute has to reach to be recognized as critical. The most important values are those shown in Tresh and RAW columns. The window in the left shows the list of attributes with their values. Please note that SMART is not supported for USB drives.
