In reply to wilkie14c:
> is it formatted to the correct format? Using it on a Mac means it could be APFS or Mac OS extended. Using it for windows you’ll need to format it NTFS and then initialise the drive. All done in disc management and should be easy following a youtube guide
I wondered about this but of course but didn't find it appear so couldn't format it .
I'll check disk management later, but I would have thought it was something I would have looked at when I tried to diagnose its issue .
I do remember device management finding it when plugging it in though but not appearing on the desktop.
