I did try it internally. When I booted up my computer, it brought up a message saying that my hard drive had exceeded its normal storage space (I assume that meant that it was recognized). This message was displayed before Windows booted. When I checked Explorer, I didn't see the drive. I also checked Disk Management and it wasn't there. The drive may be damaged, but it still spins and powers on fine. It could easily be a problem with the enclosure itself, so if it doesn't work, I can try a different one.
