Reformatted drive not showing up

[lizcoleman]

I've got a WD My Book 1110 external hard drive, originally for Mac. My Mac died and so I got a Windows 7 machine. I extracted all the data, reformatted the two partitions I had on the drive, and moved the data back onto it. The partitions showed up with letters, all was fine, until I restarted my machine. Now I can't access the drive. It shows up in Disk Management, lists the properties, but the drives aren't assigned letters, they don't show up in Explorer, and Disk Management says the partitions are 100% free. Also in Disk Management, when I right click on the volume, all options are greyed out except Delete.

Taking some cues from the internet, I've already tried uninstalling the drivers (it says they're up to date, and said it reinstalled them fine, and that the drive was ready to use, except it still doesn't show up.)

I admit I've only got basic computer knowledge. Did I just screw up my drive? Thanks in advance.

You say you "moved the data back onto it".

Is that data backed up somewhere else so you can afford to reformat this drive?

If so, I would use the Diskpart command and then run "clean" to wipe the disc. Then reformat from within Diskpart.
