Pengo Computer 3.5 HD IBM FMT DISK COLOR-W/LABELS 50PK ( 50050 ) (Discontinued by Manufacturer)

So far I have used only a few but they all work great! You never know them being obsolete. I expect to have problems. I have not had a one!UPDATE: About ten disks into the box and they have not been formatted. It's not a big deal to format before using. I have had three so far that are bad. I am about 3/4 through the box. Still a good deal.

I was surprised that all of disks I've tried so far have worked flawlessly, given I've had luck with other brands in the past.

So far so good. Arrived real quick.

Unfortunately , A Lot Of The Disks Don't Even Work.

More than half were no good. I'm lucky if half a dozen of them worked. Waste of money.
