Hard Disk Monitoring

Hi,
I'm having doubts with HDS because sometimes it shows me that the HDD si defective or the Health is low with many erros on clusters and sectors, but the HDD in Windows works perfectly and copy at 27mbxs, so I dont know what to do...thanks to everybody albert

Hi Albert,

There are some topics already cover this question and give detailed answers, for example:

In general, the bad sectors (Sentinel never reports bad clusters) reported are already fixed by the hard disk: the disk no longer uses them, uses the spare area instead. That's why you may not experience issues in an ideal case. However, if the number of such sectors is high or if the number is continuously increasing when the hard disk head moves to the problematic area, this may lead to data corruption or even data loss.
Reading/writing other parts of the hard disk (and accessing the spare area) can be fine so it is possible that you do not notice issue until it would be too late.

Please check the above mentioned topics for further information.
