My external hard drive died out of nowhere. I plugged it as usual and it didn’t detect. So I disassembled the external and installed that hard drive into the desktop. When I boot up into windows it detects the hard drive but it shows as an unallocated drive.

Is there any software (free or for purchase) that will allow me to see my data?

Just recently I attempted to backup some of my files to an external hard drive using Windows Vista’s Backup and Restore center. I noticed that during the backup, about 1 GB of data showed up on my primary hard drive. What are these files, and how do I remove them?
