My Passport Ultra is now unrecognised

My boyfriend’s computer D drive had an error which meant he couldn’t access it. We decided to plug my passport ultra into his computer to transfer what we could from his D drive but as a result my external hard drive has not been recognised on any computer since. I have now tried it on three computers in total.

Originally when I plugged it into my computer it said it had an error and needed to be scanned. Following this it said it needed to be fixed, which I also selected. This failed and nothing has happened since.

Any suggestions on how to fix this?


Please see if the following links helps.

How is the drive showing on disk management.

Also try using the DLG tool to test the unit. It sound like a data corruption issue.
