Hi,

 

one of my drives shows a smart error. Should I change the drive?

If Selective self-test is pending on power-up, resume after 0 minute delay.

 

Bye.

I would replace any disk with pending sectors, after you can run a few preclear passes and see if the pending sectors go to and remain at 0, though I would only re-use a disk like that for backups.

I see. I'll replace it.

36000 hours run time.  That's over 4 years.  Yeah, time to replace that drive.

LOL...what should I say? For years this system was running 24/7.

I agree you should replace disks with pending sectors ... but not just because they have 36000 hours on them.    I have several disks with over 55000 hours that are still running just fine, with no pending or reallocated sectors.
