40+ IDE Hard Drives, mostly in the 4GB to 8GB range. A few SCSI drives and 1.44MB floppy drives as well. Most work fine, I'm sure there are several that may not. Also included is a nice drive home made USB drive rack for powering 4 5.25" drives, and attaching via a single USB port. They'll be available for a few days or so before they get pitched. Free Storage!!
