Attaching 5.25″ floppies via USB

Floppy disks are a relic of the past these days. You might still see the odd 3.5″ floppy – and there are even still companies making 3.5″ USB drives you can plug into your system today. But 5.25″ floppy drives (360k and 1.2 meg variety) are much more scarce. So scarce, in fact, that you’re likely not to find any outside of old vintage computers. Most modern PC’s since the Pentiums don’t even have connectors or interfaces that support them and I know of no vendors that make USB 5.25″ drives.

So what is one to do if they have old 5.25″ floppies they need to read? Turns out others have had the same problem – so you’re not alone. You have the following options:

  1. Find a service that will convert them – Usually for a fee around $5-$10 per disk.
  2. Buy an old vintage pre-Intel Core based computer from eBay that has a working 5.25″ drive.
  3. Use a 5.25″ to USB converter.

One thought on “Attaching 5.25″ floppies via USB

  1. Nice, little write-up. Do you know why 3.5″ USB floppy drives with read/write exists but not for 5.25″? Is it solely due to lack of market demand or is are there technical reasons?
