5 unreadable sectors

[dominator99]

I have a 4TB Western Digital HDD that stablebit scanner 2.6.9 reports as having unreadable sectors.  I ran Western Digital Data Lifeguard Diagnostic for Windows extended tests (8 hours) & this reported the HDD as good (SMART also reported as good).  I also ran HDD Regenerator sector checks which also reported the HDD as good.

Is this a false positive?

Modern drives will automatically attempt to repair bad sectors and/or replace them from a reserve built in for that purpose; since Scanner runs in the background it can trigger an alert before the drive can finish, so if Scanner and manually-run tools now can't find the problem that's most likely what happened and no reason for concern (unless it starts happening a lot).

Maybe I didn't make it clear; the HDD passed tests with both pieces of software listed above (Western Digital Data Lifeguard Diagnostic for Windows extended tests & HDD Regenerator sector checks) but stablebit scanner still shows unreabable sectors after passing both these software tests. If I mark all unreadable blocks unchecked then the unreadable marker disappears but reappears at the next stablebit scan.

Ah, okay. Yes, I'd open a ticket with StableBit if Scanner keeps finding "bad" sectors where all other tools don't.
