As has been griped about in the past, I went on an all out google search for a 5.25" drive married to a USB adapter. Thought I almost had one when I saw a picture on the Teac website of what turned out to be a USB to IDE adapter they sell. I contacted them anyway and inquired about hacking their 3.5" USB drive. Their reply: Hello Robert, Unfortunately, TEAC did not make an adapter to convert a standard 5.25" floppy drive to USB interface. There is no solution that we can offer you. The USB 3.5" floppy drives can not be dismantled as these don't have a USB adapter, instead the USB chip is already built-in its main PCBA. Therefore, there is no single part that can be used to convert a 5.25" drive into a USB interface drive. You may want to search online; perhaps another company offers a conversion kit for a 5.25" drive. Regretfully, Mario Gomez Customer Support Manager Data Storage Prod. Division TEAC America, Inc. Ah, well. Looks like if it can happen at all, it would have to be home-brewed. Bob Stek Saver of Lost Sols
