I have a 40GB hard I took out of my (fried) desktop computer and put it in an external enclosure that converts to a USB hard drive. I hooked it up to my laptop and it worked fine. When I got the original computer, though, it had two partitions: one 30GB and one 10GB. I wanted to merge the two partitions without buying something like Parition Magic (since it’s a one-time thing). So, I downloaded a simple, DOS-based tool from Microsoft that lets you do a few things with drives and partitions. It’s very primitive.
The long and short of it is, I managed to logically erase my hard drive. It now has no file system, drive identication, etc. When I plug it in to my laptop it is not recognized as a drive (I don’t see an additional drive under My Computer). If I go into My Computer->Manage->Disk Management, it shows two physical units – 1 and 2. It shows ~40GB avail on unit 2. I select unit 2, right-click, and I don’t have the option to format it. I can only access the properties.
I don’t care about the data that was on the drive; I just want to format it so I can use it again. Any idea how to do that?
