I have to ask...why use the 32MB jumper setting?
I would have just connected it directly to the motherboard (if possible), using the appropriate jumper setting. That eliminates a few possible complicating factors if the drive doesn't work.
If you can see the drive in Disk Management but you cannot see the file structure...chances are the file structure or the drive itself is in trouble and you may need to try data recovery software to access any files on said drive.
