External 3.5" HDD Problems

I just built a new computer and installed Windows 7 Professional 64bit onto it.

Before this I was using a laptop with Windows 7 on it as well. When I was finished building my new computer, I decided to start transferring my files over. The network would be way too slow, so what I've done is used and IDE-USB adapter that I bought (This works on 3.5in HDD's as well.) to hook the HDD from my laptop into a USB port on my computer.

I can view files fine, and transfer a great deal, but when I try to transfer my music in particular, all of the sudden windows can't find the files. It says they've been moved or something. I can see the files when I browse the drive at this point, but can't play any of the music or move anything either.

Has anyone encountered this problem before?

Any help is appreciated

Check your HD.

Disk Check

Check with a hard drive diagnostic tools.

i think I figured out my problem. The HDD I was trying to transfer from had a copy of windows running on it, and was set as the "master". I was able to transfer files to an old HDD that I had laying around and get them onto my new computer.

Thank you for your assistance :)
