Watch out the PS/2 30 may be ESDI not IDE.

The IBM drive just unscrews from the platic housing and it's just a 2 1/2 inch
IDE drive with the power on the additional pins. The standard $5.00
2 1/2 IDE to regular IDE should work, I think...

I've got one and it seemed to be a standard IDE laptop drive (340mb).
