Drive with errors "fixed" by SeaTools, but...

[Z300M]

One of my 2TB Seagate drives (ST2000DM001, no longer in warranty) had problems

"Device: /dev/da15 [SAT], 8 Offline uncorrectable sectors
Device: /dev/da15 [SAT], 8 Currently unreadable (pending) sectors"

and I have replaced it. Connecting the failed drive to a Windows machine and running the SeaTools "Fast Fix" on it claims to have fixed the problem and the drive now shows no errors. BUT how safe is that drive really? Is it worth keeping it in reserve to use as a spare in case another drive develops problems, or shall I just find another use for it in a non-critical situation?

All it did was successfully re map those bad sectors. I would NOT use that drive in anything where your data actually mattered.

The only way to know for sure is to monitor it in use. If more bad sectors appear, it's bad, otherwise, it's fine. Which is to say, I agree with @Jailer.

I ran Hard Disk Sentinel Pro's most exhaustive test (read,write,read; 36hrs) on it with no errors reported, but I'll demote the drive to a mirror in my Linux desktop machine.
