Reformatted drive not showing up

I’ve got a My Book 1110, 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, and they don’t show up in Explorer. I admit I’ve only got basic computer knowledge. Did I just screw up my drive? Thanks in advance.

If you have backup you can reformat the drive to see if it will work again. 

Tried using the drive with Windows Vista or XP since the drive might not work well on 7

Did you try assigning new drive letters? You can try going into Device Manager and delete the driver for the drive disconnect it and reboot system. After reboot hook the drive back up that will load a fresh driver.

All options when I right click in Disk Management are greyed out except Delete. It also seems to think my partitions are 100% free. (it gets the size of them correct, just not the fact that there’s data on them) Earlier, I tried to uninstall the driver, then reload it. That time, it said the driver couldn’t be installed properly. I tried again just now, and although it says the driver was installed fine, and the drive was ready to use, it still won’t read it. The data on that drive is the backup. It’s not super vital info (all that has already been transferred to my PC ). It just means I’ll have to re-rip all my CDs.
