- What's that mysterious software you downloaded (and probably installed), but that only worked for a week?
- What "library" is your desktop in? Or must I ask: what "library" is in your desktop?
- Does "everything" include reinstalling that software?
- What more did you do to try to fix it?
- What filesystem does Disc Management show on the partition(s) on that disk?
- Does it still work on a Mac?
- Where's the backup of that extremely valuable content? It's well known (in these forums at least) that an external hard disk a very unsuitable device to contain the only copy of anything you don't want to lose.
My external hard drive, a Seagate BUP BK (4tb) works on macbooks, but seem to have an issue with my windows desktop (Windows 10). First time connecting the hard drive, it didn't show up in my library, but it did show up in disk management. I fixed it by downloading a software. It worked for a week, until today. I have tried everything to fix it again. The unit shows up everywhere, except in the library where im supposed to be using the hard drive.
Please help. (Also, i can not format the disk as it contains extremely valuable content)
