April 26, 20206 yr Hey everyone. I recently set up unraid about a week ago and everything was going fine. I upgraded my drives recently starting with my parity of 2tb to 8tb. I followed the guide on the Wiki and no problem there system was up and functional. After that I needed to upgrade my data drive. In this case I removed a 2tb drive again and upgraded to a 8tb drive. At some point during that the build failed and it ran a read check on that brand new 8tb drive (Shucked WD Easystore White label). Read check passed however the drive still shows disabled and I cannot enable it. I get a CRC Error and I have replaced the sata cable and it also happens on my SSD cache. This SSD is only 1 year old and shouldn't have this error either and if it matters I added the cahce and the 2nd 8tb drive (the data one) at the same time. Do I have a bad sata controller on my MB? Can I re enable this drive? Is there a Sata HBA someone could recommend? Thanks System Info M/B: Supermicro X8DAH Version 1234567890 - s/n: VM21S56452 BIOS: American Megatrends Inc. Version 2.1.

April 26, 20206 yr Community Expert Check all connections, power and SATA, both ends, including any power splitters. Disk looks fine so you can rebuild it to itself if you want. Do you know how?
April 26, 20206 yr Author I have checked all cables again and confirmed should be no issues there. I still see the drive as "Device Disabled Contents Enumerated" and only have the option to start the array or start it in maintenance mode. Once I start it I do have the option to do a read check on all devices. what step should take next?
April 26, 20206 yr Community Expert The steps to rebuild a drive are covered here in the online documentation. It has a specific mention of how to rebuild a disk onto itself if it has been disabled but you decide the drive is actually OK.
April 26, 20206 yr Author Thanks parity rebuild is running now. Hopefully this should be the end of this
