November 30, 20205 yr I use a WD elements 10T hard drive, I format the disk by use USB, and it works well. When i take the hard drive out directly, and use SATA , the unraid can't recognize the filesystem and remind me to format the hard drive. And I try push the hard drive back, and use USB, it works well. Do I need reformat hard disk when use SATA directly?
November 30, 20205 yr How are you connecting the drive to USB ? Are you using a standard SATA to USB dock or the WD board that came with the disk enclosure ? Edit: also and more importantly : did you look into the 3.3V issue ? WD tends to disable some drives if connected to 3.3V. You can find plenty of details and workarounds on this on the internet. Edited November 30, 20205 yr by ChatNoir 3.3V

I also notice the 3.3V issue ,and I use the cellulose tape to sheild the three 3.3 contact points, but unraid shows unformating disk too. If the reason is 3.3v issue, i guess i can't see the disk in unraid?
November 30, 20205 yr Community Expert It is not unknown for USB enclosures to report the disk geometry slightly differently to the way it is reported via a direct SATA connection. If this is the case that is being encountered then the drive will need to be reformatted from Unraid.
November 30, 20205 yr Community Expert WD usually encrypts the disk when using the USB enclosure, you need to re-format it outside it.
