skyhawk Posted December 3, 2015 Share Posted December 3, 2015 Had an issue with my server and a bad power plug on a hard drive. This caused the drive to go offline and caused me a ton of frustration until I figured out that a 25 cent part was the source of my problems. Shortly thereafter or during the issues, the drive popped up with 240 reallocated sectors. This is a new drive (30 days) and I could possibly still return it for an exchange. Thoughts? It originally passed 1 preclear successfully and then I loaded it with about 1.5TB and had no issues for a week or two.

BRiT Posted December 3, 2015 Share Posted December 3, 2015 I would move the data to another drive and put it through 2 more cycles of preclear. I have found 1 cycle is not enough and had drives die during cycle 3. Quote Link to comment
RobJ Posted December 3, 2015 Share Posted December 3, 2015 I agree. With 240 remapped sectors already and 27 different reallocation events, that's somewhat troubling. What's amazing is that 240 didn't even bump the Reallocated Sectors count VALUE, indicating the drive may have more than 24000 spare sectors! That's a lot, perhaps they are expecting a lot of reallocations?!? Quote Link to comment
skyhawk Posted December 3, 2015 Author Share Posted December 3, 2015 I'll run a few more preclears, but will it possible fix the reallocated sectors... Or just confirm its not worse than that? Or I'm against the timeline for returning to Amazon, so should I just return it and call it a day... When I got the drive, the first preclears took almost 3 days. I had limited time so only got one done. Quote Link to comment
archedraft Posted December 3, 2015 Share Posted December 3, 2015 If it was me I would just return it or exchange it on Amazon for a new one. Re-running the preclear will not remove the reallocated sectors (they are permanent), you would just be confirming that it isn't getting worse. Quote Link to comment
