USB Cable to 34 PIN 34P Floppy Interface Adapter PCB Converter Board Driver Board

This is, effectively, the "guts" out of one of those external USB floppy drives that you see from time to time. It converts the standard 34 pin floppy interface (and 4 pin power) into a usb device that reports as a TEAC SCSI floppy drive, and will indeed allow you to make an external USB floppy device with a 3.5" HD (1.44M) floppy drive.There are a few caveats, however:Since it is designed to be used as an external drive, it doesn't seem to bother ever spinning down the floppy drive (i.e. the drive is selected and the motor is spinning as long as the USB is plugged in) - this may not be what you want, e.g. if you are trying to come up with a solution for an internal drive, which would be permanently connected.Whilst the device has a power output, and the cable to connect to the 4-pin power connector on the drive, I'm not convinced that it can power a standard "full size" 3.5" FDD, but it powered a slimline laptop drive fine.There may be some drive select issues, as I had problems with some of my legacy 3.5" drives configured for "cable select" - some jumper fiddling on the drive may be required, but, again, it did work with a slimline laptop drive, where multiple drives were never a problem.I should also point out that the device arrived without any packing material (no antistatic bag, no bubble wrap, literally, just an opaque plastic bag with a postal label on it) - I'm sort of impressed it made it in one piece, but it did - I'd have been more comfortable if it had been in a jiffy bag, or equivalent.So, as a summary, this will help if you need to build your own external FDD solution (but make sure the current requirements of the drive aren't too large) but is unsuitable for an internal solution unless you like hearing the drive running all the time, and don't want to have a floppy anyway (continuous operation will wear out most FDDs pretty quickly!) - just make sure your use case matches the products capabilities!

I needed to copy data from some old 3.5" floppy disks onto a modern Windows 10 desktop as a one-off task. I had a couple of old desktop floppy drives in my PC bits box and this little adapter was perfect for the job. I tried it on both drives and they both worked. I wouldn't recommend this for permanent connection to a PC (the drive runs all the time) but as a cheap way to access the data on old 3.5" floppy disks it's great. The attached photo shows the adapter connected to one of my old drives.

This is an end of life floppy drive with the interface end chopped off and mounted to a USB controller board.This is not mentioned and therefore will not have low-level access to any floppy disc you insert (i.e. does not emulate a motherboard floppy controller). That assumes you can get it working in the first place.Save your money buy a proper USB floppy drive if you just want to access old data, or buy a mid-2000s motherboard bench setup or recycle a PC of that era to get full low-level floppy support.

I used this to read 5.25 and 3.5 inch floppy disc files. It worked fine but you need software that recognises your files.

This circuit board re-purposes a Floppy Disk Drive. The circuit connects to the FDD 34 pin connector, its a tight fit. A connector cable connects the USB circuit to the FDD power input. Special note: MS windows, all versions, up to Win 8.1 support FDD drivers but some newer versions of MSWin10 don't include FDD drivers but there is an Internet available solution.
