Thanks for your message.
Excuse me, but it is not a bug (the "bug reports" section is designed for problems encountered in the software).
The good news is that the "bad sectors" reported in the text description are no longer used by the hard disk: they are already reallocated.
So a special spare area is used for all reads and writes targeting those bad sectors.
This means that disk surface tests (even the tests in Hard Disk Sentinel) does not
access those sectors, but tests the remaining data area and the spare area.
This is good, as this way you can be sure that the original (bad) area does not
contain important data and can't risk data loss.
By using the Disk menu -> Surface tests, you can verify if the currently used data area is error-free, there
are no further errors reported (no weak, damaged sectors, no further problems).
For more information about these "bad sectors", please click on the "?" next to the text description
(the text area describing the issues) and check
http://www.hdsentinel.com/faq.php#health and
http://www.hdsentinel.com/faq.php#tests
The tests described on the above webpage help to
- identify further disk problems
- repair possible problems
- verify if the hard disk is now stable and error-free
In this case you can even acknowledge the problems reported by Hard Disk Sentinel and clear the errors from the text-description - so they will be no longer reported by the software. This would result in increase of the hard disk health as well.
