I've read many times that USB floppy drives will not format (or read/write) 720K disks. But then I read several posts online where people say they have done it. Even with Windows 10 (which is what I'm using).
One instance said to use the following command at the DOS prompt:
format a: /f:720
When I did that, here is what I got:
format a: /f:720 Insert new disk for drive A: and press ENTER when ready... The type of the file system is RAW. The new file system is FAT. Formatting 720 KB Parameters not supported by drive. Format failed.
Just like the message said, the format failed.
The disk I'm using should be good but I cannot completely confirm. It's also the disk that only has the one hole. The cover says:
FUJI FILM Micro Floppy Disk MF2DD Double Sided Double Density 135 TPI / 80 Tracks
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).
I can't find the model number. But it was highly rated on Amazon and some people even said they used this exact drive to format 720K.
Here is where I bought it:
The company is Chuanganzhuo.
On Stephen Kitt's suggestion, I tried a standard "format a:" but it didn't work.
Insert new disk for drive A: and press ENTER when ready... The type of the file system is RAW. The new file system is FAT. Verifying 1.44M Invalid media or Track 0 bad - disk unusable. Format failed.
