How do I fix my hard drive with HD Sentinel?

When they reported, Hard Disk Sentinel can help to diagnose and repair them, usually they can be completely repaired with Hard Disk Sentinel by using Disk -> Surface test -> Reinitialise disk surface test.

What reduces HDD Health?

Perform Defragmentation Fragmentation deteriorates your hard drive health significantly, as new data is stored in fragments that cause massive movement of the read head and increase disk spin speed, which causes more wear and tear besides overheating—a major cause of drive failure.

How do you know if a HDD is failing?

Common signs for a failing hard drive include sluggish performance, unusual noises (clicking or loud component sounds), and an increase number of corrupted files. These are textbook symptoms for the inevitably of a failing hard drive and action should be taken quickly to save your files from being lost.

Is HDD Sentinel accurate?

Yes, it is completely expected that the results are same, as Hard Disk Sentinel also performs those hardware tests. Just Hard Disk Sentinel offers much more tests in Disk menu -> Surface test, which are more sensitive to errors and possible (even minor) issues.

How does hard disk Sentinel check the health of an SSD?

The “wear-leveling” feature of the SSD tries to hide/minimise this effect but generally the SSD device reports the overall health of the memory cells by various attributes. If there are no further problems found, Hard Disk Sentinel reads these attributes which determine the complete health of the solid state device.

What happens if the health of a hard drive is 0\%?

Generally if you receive the alert on startup and the health is 0\%, then I’m afraid the errors are too much with the drive: the error-level threshold already reached. If you can still use the drive, backup – it is a lucky situation – as most drives fail completely before this point, causing partial or complete data loss or “just” data corruption.

Is my SSD in good condition?

As the software displays the status is PERFECT, there are no problems with the SSD. Yes, the health is not 100\%, “only” 99\% – but it is still “EXCELLENT” see next to the health \% bar.
