January 11, 20233 yr Under normal circumstances I wouldn't be asking this question. So on New Years day my server began its monthly parity check. I was out of town and woke up to an error email stating that one of the drives was offline because of a bunch of read errors. On our way home I ordered a new drive that arrived two days later. Swapped the drive out and rebuilt the array. No issues. I ran multiple diags on the drive and they all passed. It's a Seagate Ironwolf NAS 4TB and is only a year old. Fast forward to today I decided to put that drive back in to replace my oldest 2TB drive. Within about 20 minutes of starting the rebuild the NEW drive is getting a bunch of read errors. I replaced the SAS to SATA breakout cable from a spare I have and started the rebuild. I noticed it was saying the file system on the emulated drive was unmountable so I stopped the array and then started in maintenance mode to repair the file system. Started the array back up and it's now mountable and rebuilding. So, this brings me to my question. If I hook the 2TB drive up via USB how do I compare the data on that drive to the re-built data to verify it's integrity? unraid-diagnostics-20230111-1627.zip Edited January 11, 20233 yr by Taddeusz Add diagnostics
January 11, 20233 yr Community Expert I would suggest the you post up your Diagnostics file in a NEW post. The Gurus really need those files to figure out what is going on. Another question--- Did you run a long diagnostics test on the 4TB drive? (This will probably take 8-12 hours to finish...) Edited January 11, 20233 yr by Frank1940

I've added diagnostics but not sure it will show much since it's been rebooted since the read errors popped up. I didn't run any diagnostics on the NEW drive since I felt like this was a repeat from the other drive. I did run two full diagnostics on that drive and no read errors or sector reallocation are indicated in the SMART data on either drive.
