January 30, 20224 yr Been getting read errors the past few days for one of my drives. SMART report is attached. I have not run the extended test, which will take all day (but I could, if helpful). Should I just replace the drive? If I do replace it, is the drive likely not usable anymore? Thanks for the advice. ST8000DM004-2CX188_ZCT27J50-20220130-0716.txt tower-diagnostics-20220130-0752.zip
January 30, 20224 yr Community Expert Theoretically the errors shown are not fatal, but they are never a good sign. You could try running the extended SMART test to see if that completes successfully. 31 minutes ago, volcs0 said: Should I just replace the drive?

The results would give you an idea if the drive is still usable.

OK - I will replace the drive. On the same server, can I mount the old drive as an unassigned drive and (1) run the extended SMART test and (2) run a pre-clear? Will that work? Should I wait until the parity rebuild is finished on the new drive? Thanks.

I would avoid running a preclear until the rebuild is finished just in case the rebuild goes wrong and you need to try and get something off the old drive. The SMART test can be run at any time as it is non-destructive.

Then will put drive back in and run a pre-clear on it (is this still possible in 6.9?)
