A DD disk will always end up formatted in double-density, and a DD drive will always format in double-density. Note that the holes in disks’ cases don’t determine the formats one-for-one. All is not lost though: you should format your disks in the Tandy’s drive (when you get it), and check whether your USB drive can then read and write the disks (but keep some disks aside that will only ever be written to using the Tandy’s drive). High-density and double-density disks use magnetic media with different coercivity, requiring different field strengths to write data a double-density drive can’t reliably format or alter a disk that’s been written to by a high-density drive. However since your intention is to use these disks to transfer files to and from a computer with a double-density drive, this approach is likely to be unreliable anyway. If you have a Linux system handy, you can determine your drives’ capabilities by querying it with ufiformat -i. To see what it does - USB drives control formatting themselves, so this should do the right thing if it supports double-density disks. It is still worth trying a plain format a: There are some USB drives which support double-density disks and formats, but as you suspect, not all of them. Invalid media or Track 0 bad - disk unusable. On Stephen Kitt's suggestion, I tried a standard "format a:" but it didn't work. But it was highly rated on Amazon and some people even said they used this exact drive to format 720K.
Is this possible or am I going to have to do something else? I plan on swapping my Tandy 1000 EX's 5.25" drive with a 3.5" version and I'd like to transfer images over that way (sneaker-net). It's also the disk that only has the one hole. The disk I'm using should be good but I cannot completely confirm. Just like the message said, the format failed. When I did that, here is what I got: format a: /f:720 One instance said to use the following command at the DOS prompt: format a: /f:720
Even with Windows 10 (which is what I'm using). But then I read several posts online where people say they have done it. For more information see thelicense.I've read many times that USB floppy drives will not format (or read/write) 720K disks. However ata minimum you should incorporate or link to the COPYINGfile on your selling page.
This means, for example, you are free to sell and profit from Gotekdevices programmed with a binary release of FlashFloppy.
Because FlashFloppy includes third-party code, you shouldinclude or link to the COPYING file in any redistribution. The source code, and all binary releases, are freely redistributablein any form.
Most code is public domain the rest is MIT/BSD or Open Source friendly(see the COPYING file).

Working of Single Block Format of floppy drive to usb software.įlashFloppy is a labour of love: working on it takes a lot of timeand effort. This floppy to usb software is must for use with models 1.44U100, 720 kb U100 and 1.44 USB Floppy. These type of applications are generally required when machines uses propriety operating systems other than FAT types.
