This is a sealed bag of (25) plus one single 5-1/4" floppy computer disks that my father had with all his computer stuff and I inherited. Besides the sealed bag, he also had a partial bag and from that is the single disk that I am showing, and I am throwing in the sale.
Knowing my dad, these are most likely high-capacity disks, but I don't have a drive anymore that I can check them, so I say they are Untested.
