June 15, 20242 yr Hello I decided yesterday to replace one of my old 1tb drive (the smart report was starting to show bad sectors plus was a very old drive) with another 2TB that I had lying around. The day before I ran a parity check and everything was okay no problems. I did the swap, started the rebuilding process, the speed was around 100+ mb/s and left it to run overnight. And I guess overnight the parity drive decided to start failing. The speed now is usually around 50 kb/s and sometimes jumps to 5-10 mb/s for a minute or two. The logs show an insane number of read errors in the parity drive. Plus in the smart report, the parity drive started to show read failure and Reallocated sector count The rebuild process is around 85% So the question is, do I leave it to continue? Is there a way to keep 85% of the rebuild data? or is it all or nothing? Is there an easy way afterwards to find which files were corrupted. ** I was stupid enough to throw away the drive I replaced before the rebuild finishes. tower-diagnostics-20230227-1151.zip
June 15, 20242 yr Community Expert Your replacement drive is an SMR drive, they are terrible at sustained writes like what is being done there. It is all or nothing. You can pause the rebuild, wait a couple of hours and resume, it'll run normally for a while until it slows down again, if you keep repeating that it should be faster than just waiting.
