I got garble when I plugged in my REALLY old 46 MEGABYTE drive to see what I had on it. It didn't work, but it was recognized with completely random characters, mostly square boxes.
As Broni Suggested a screenshot of exactly what it is being called and how it is presenting this information would be most helpful.
Can you access the drive / have you tried it on another computer? I wonder if the sector where the info for the drive is corrupted?

I believe the name description passed back to the Controller when the Hard drive is asked to identify itself with the ATA ID command is actually stored on one of the ROM chips on the hard drive... more then likely the USB interface is munging it up before passing it to the computer.
