Question: Is this a 5 1/4" drive. It doesn't say an even though it came from a search for '5.25 1.2mb floppy drive' I've learned that means nothing on Amazon.
Document: I have received two of these drivesNEXARK SABRENT External USB 1.44 MB 2x Floppy Disk Drive SBT-UFDB (Black). The 1st one was dead out of box. Nothing in the box but the drive. Looked like it was used (shame on you Amazon). I say that because I asked for a replacement and it was in a sealed box in a plastic bag with internal cardboard packing. The 2nd unit was recoginized by Windows but would not recognize any disk that was inserted.
I've been using 3.5&#34; floppy disks and drives since they came onto the market. This one has hesitated to initiate the read a couple times to the point that I had to remove the disk and reinsert it. I am not sure if that is because of the condition of the data on the disk or the drive but instinct tells me the drive might have a slightly out of spec mechanical part.
(I disconnected it, reconnected it -- nothing worked. )I've tried attaching it to a Powerbook, and the drive's green light won't even come on when I put a disk in.So, a this purchase was a waste of money. Not only couldn't I copy my files, I now can't even SEE them. I will be returning this drive!
you a\can not go from one disk to another with out having to disconnect the unit.Can not read some of my disks , Keeps telling me to formate my disk even if it read it yesterday.When I called for some help all I was told was &#34;that's it. Theres nothing we can do.I am getting ready to return this unit back to Amazon. Not happy with it at all.
This is the first USB floppy drive I've purchased, so I don't know how others may compare. It has worked just fine, but is much slower than any internal floppy drive I've ever owned.Not a huge problem - everyone is moving towards USB flash media anyhow. I guess I can say it was an OK purchase for the inexpensive price.
The NEXARK SABRENT External USB 1.44 MB 2x Floppy Disk Drive SBT-UFDB (Black) works as advertised. No issues reading some old 1.44 disks I came across. Ordered and recevied promptly!
As others have said, the interface is from Teac but the actual drive is junk. It did not work on 3 different computers - both Windows XP and Windows 7. I found a drive from an old IBM laptop and made use of the interface. Don't buy this product unless you are willing to do your own composite. There are so many old floppy drives out there that it is disappointing to get one that wouldn't even work. I would give it less that a 1 if that were possible.
This is the first time I've ever purchased something like this off the internet and had absolutely no good fortune with it. Like I said - it came out of the box not working. Very very disappointed and upset. Don't buy it.
They sent out an identical device with a different model number... SABRENT External USB 1.44 MB 2x Floppy Disk Drive SBT-UFDB (Black) instead of the Sabrent External USB 1.44 MB 2x Floppy Disk Drive (FL-UDRV) Black we ordered... The device repeatedly detected floppies as write-protected. Could not read/write to a single disc. 100% fail rate. The LED display did not even have a bulb behind it.
My father needed a 3.5" drive to recover some old files on floppy disk.Why did this thing have to cost more than a spindle of DVD-R's?Because its medium can hold over 1.4MB of data! That's almost 1/500th as much as a CD-R!! !Don't get one of these unless you really need to...let the old tech rest in peace.
Answer: It is a 1.44 MB 3.5 Inch Drive
