Toshiba external hard drive not detectible
I have a Toshiba DWC250 5TB external drive formatted ReFS that I cannot detect in either Disk Management or by using DiskPart/List Disk. Cabling and power are sound. The unit is not user serviceable because the case is not designed to be opened. I use it in a storage pool on Windows 10 Pro. I am having problems with the pool and removed the drive to check for files with a different computer.
I would like to use Diskpart/clean or clean all on it but first I have to get the disk detected. The unit has not shown signs of drive failure so it may be re-useable. Is there a technique to force detection (should it still be useable)? Please note the file system in not NTFS. It is ReFS. I have already detached it from its home PC and attached to a Surface Pro 4 via the Surface Dock to see if I can get it detected, but without success.
