Still trying to find a good 5.25 floppy label. They're either expired old stock, or the wrong size (like those huge-ass Averys), or they don't stick to low low-energy PVC. I just want an old-school rectangle that goes to the right of the factory label.
The Avery labels (the 5197, I think) are TERRIBLE. Not only are they too big, but the adhesive is so weak that they start peeling off the disk after only a few uses. If you print them with a laser printer, it makes the labels all crispy, and the toner also starts flaking off.
I typically use 1.5" X 4" thermal labels printed on a Zebra printer. They're a bit bigger than I would like, but they're a better fit than the Averys, and they stick to the disks much better.
