KOOBOOK 1Pcs 1.44MB 3.5" Floppy Drive Connector 34 PIN 34P to USB Cable Adapter PCB Board with Power Cable

I built a new i9 Windows 11 PC in an old ATX case and decided to keep the old floppy drive that was in there. Since my new Gigabyte MB has no connector for floppy drives, I decided to try this floppy to USB adapter. I read all of the reviews here, so the first thing I did upon receiving the item was secure the USB cord to the module to make sure there would be no added stress on the fragile glue-covered solder connections. I carefully plugged the board into my floppy drive, making sure it was not upside down or offset. Then I plugged the USB cord into an internal USB 3.2 Gen 1 port on the motherboard via a USB 3.0 to 19-pin MB adapter cable. My floppy drive was already powered from the power supply, so I did not use the short power cable that came with this adapter. Now I have Floppy Disk Drive A in Windows and it works as good it ever did 30 yeas ago. Be aware that if the floppy disk is not write-protected, any modern version of Windows will create the hidden System Volume Information directory on the floppy disk. If you don't want Windows to modify your disk, be sure to write-lock it before inserting it. I only wish I could change the drive letter, but this adapter adds the drive to Windows as the internal drive A, which cannot be mapped to a different letter. I would have preferred that the drive appear in Windows like any other USB drive, which can be mapped to any drive letter. That's not a big issue though. Overall I'm happy to be able to read my old floppies on my new PC now.

Installed this on my sleeper build, runs a little on the slow side but considering I'm using a floppy drive on a computer thats nearly 20 years older than the drive itself that is to be expected. The chip itself is a little on the flimsy side, but if you aren't stupid that shouldn't be an issue considering it will live in a steel box. One thing to note is the unit doesn't quite meet the voltage requirement to power on a drive, but its close enough to where it works. Like, the floppy drive will read and write, but its slower than if it were in a machine from the floppy disk era. That being said I'm mostly using this for very basic stuff so speed isn't an issue. 8.75/10, 5 stars overall.

I installed an old floppy disk in an old tower with new build (SATA drives). I have been working with older OS's (USB bootables & VirtualBox) and wanted it for boot disks. I have a USB external floppy, but this was partly nostalgic and the drive was from this old case. This adapter works well for that. Here is what I noted: 1) No instructions. A brief instruction card would have been good. I had hooked a connector from the power supply to the board before figuring out the jumper from the CCA was for providing power to the drive. 2) This adapter makes the drive stick back further into the case. The power connector made it longer yet. I had to bend the connector to keep the wire out of my cooling fan. Either a straight connector, or just hardwire the power jumper to the board would be better. Especially if you have a big processor fan that makes funny noises if a wire sticks in it. 3) The logic connector does not have a key. This is not unusual as some old ribbon cables also did not have it. The CCA is marked for pins numbers, so check your drive. 4) There is no lock for the logic connector. There are some through holes in the board that a small zip tie can be fed through to secure both the connector to the drive and tie up cables. 5) I have a PCIe USB card I had in an old machine that I moved to this new one. It has a USB connector at the back of the board that worked well for this adapter. Otherwise I would have had to route a USB extension cable outside the case, or see if there is an adapter available to one of the USB ports inside the case. 6) My old drive sits there and 'ticks' (searching) if there is no floppy disk in it. I suspect it may be my drive, so I'll just keep a blank disk in it rather than buying a new one. All told, this could be improved, but it does what I wanted. Hope this helps anyone interested in a little retro looking build.

This item works, but my main problem is the item is poorly constructed and fragile. The white blob of glue fell off of my item entirely. Now, I'm worried about the wires being ripped out from where they are soldered. Be warned that this item is hard to test just because so many things can go wrong: bad floppy drive, bad USB port, or a problem with power. It's also easy to install wrongly by accident, e.g. it can be connected upside down to the floppy drive, or off-by-one. Also, many floppy disks have gone bad by now. I would not use this item to power a floppy drive. It does not seem safe to do so. The USB 2.0 spec supports only up to 2.5 W but I think some floppy drives can use 3.5 W. I powered my floppy drive independently from this item, just to be safe. This item works with DS HD 3.5" disks (1.44 MB). I have been unable so far to get this item to work with a double density disk (720 KB). The USB cable was sufficiently long for my full tower (Rosewill Thor V2) case. This item works on Windows 10. Note that right-clicking on random files (e.g. on your desktop) in Windows 10 will bring up a "Send to" menu and allow you send things to various drives including A:. Unfortunately every time you right-click on a file, Windows will check the floppy drive and make some noise. There is a registry setting to disable this useless "send to drive" feature. I found Ubuntu also accessed the drive too often so I applied some other OS setting there.

Never draws more than 0.3A even while long formatting. Verified through USB inline meter. This might depend on your drive. I tried it with a couple mitsumi's and a TEAC FD505. None of them drew more than 0.3A. Unfortunately my FD505 doesn't read disks anymore, the stepper motor for the read arm on the 3.5 click but don't move and LOL I don't have any old 5.25's to test. I suspect the electrolytics have dried out. But it wanted to work which tells me this device is issuing the proper commands. With that said, this allowed me to read and write all my old 3.5" floppies. Haven't looked in like 20 years. Found a Win98 boot disk, woohoo! I admit the hot glue is an amateur move but there is a hole in the card near the back edge that you can secure the cable to the card with a small zip tie. Works like a champ. Inexpensive and works. Can't beat that.

This product arrived promptly, was packaged appropriately, and was sloppily built. While inspecting it, I noticed that the #34 pin was bent (see photo). All the other pins are 90° but this one isn't. It looked like it was making contact & soldered, though, so I proceeded with the installation. By the way, there are no instructions. The power cable loops back to whatever 3.5" drive you're using. In my case, it was a salvaged 25-year old Panasonic drive. I plugged it into my lab laptop & the light flickered. So it powers the drive from USB fine. I inserted a diskette. The light stayed solid. And... after several minutes of circling rings on the screen & various soft sounds, I got a message that it couldn't read the disk. I'll try another drive -- I have a couple more in the "junkyard" -- and amend this review as necessary. But this is a quickie build job. Even if it worked, I'm not sure I could rate it more than a "3." A simple plastic box with strain relief would be a major improvement, but then I wouldn't have seen the bent pin.

Value for money, installs easy, good length

It works but you have to be super gentle with it cause the glue doesn't glue and the wires aren't soldered on that well. Had to resolder them back on. Cord length is enough to put the wire from the card to the floppy drive, but not long enough to reach a motherboard if you were to put it internally. Not easy to install, you gotta give it a good push, and since the wires will literally just pop off it's not that great. Way too much money for something that was probably 2 cents to make.

I thought it would fit on a floppy drive

Works as advertised. I can now hook an internal 3.5 inch floppy drive to my main computer. Mostly use it for transferring programs to and from my old Windows 3.1 486DX2 66.

I got this to get my tower PC an internal Floppy drive. While it does work and fits nicely inside my PC without protuding for some reason it's limit to only reading 1.44M Floppies and 720K Floppy's don't read. Not sure if this is a limitation of the adapter or the drive itself, but for what I needed it does work
