  • I'm having an issue with a shucked Seagate hard drive. Wondering if anyone had experienced the same or had any tips.

    4TB drive, works fine in the USB caddy. When I connect it directly to my PC the drive shows up in Windows 10 and is assigned a drive letter but can't be read and says it needs to be formatted before use. I put it back into the USB case and it still works OK. It is formatted as NTFS.

    Disk manager for the direct connection shows:

    Any ideas?

    I could copy the content over to another drive and format it but only really want to do that if it's going to work as copying 3TB over USB takes a while.

  • I didn't have one handy so decided to copy stuff off and try reformatting. Initially it seemed to be split into two partitions and I could only format one, regardless of attempts to wipe, extend, etc.

    Eventually ended up using Diskpart to Clean it and then creating a partition with Minitool Partition Wizard. So far as I could gather the problem was something to do with a missing GUID Partition Table but works fine now.
