Similarly, floppy1 is backed by floppy_b.flp created in the same way. IBM used this format on their PS/2 series introduced in 1987. Option 1: Use a New USB Floppy Drive If you browse Amazon, Newegg, or even eBay, you’ll find many inexpensive (anywhere from 10 to 30) modern USB 3.5-inch floppy drives. Some Microsoft DMF floppy disks contain information to make them write-protected under Windows 95/98 or Windows NT 3.5x. These sticky paper tabs are folded over the notch in the side of a 5-inch disk to prevent the computer from writing data to. I have floppy0 configured to be backed by a simple file floppy_a.flp, created for me by WS using the "Create." button in the WS Floppy Drive UI. These HD disks had an extra hole in the case on the opposite side of the write-protect notch. I can power-cycle the VM and the data are still intact on their respective disks afterwards (verified again using "dir a:" and "dir b:" and examining the volume label). With the aforementioned MS-DOS 6.22 VM (and with the second FDD configured in BIOS setup), I can successfully "format a:" and give it a label (FLOPPY_A), then "format b:", give it a different label (FLOPPY_B), and "dir a:" will show the contents of the first floppy and "dir b:" will show the contents of the second floppy. Floppy drives are very much non-plug-and-play like that. I've tested an MS-DOS 6.22 VM with Workstation 9.0.1 (build 894247) on both a Debian 6.0 amd64 host and a Windows XP Pro SP3 host, and could not reproduce your findings.ĭid you go into the VM's BIOS and configure the second floppy drive? If you don't do that, MS-DOS goes into its crusty old "pretend we have two floppy drives when there's really only one" mode, you'll get occasional prompts to "Insert diskette for drive B: and press any key when ready", and all reads/writes will go to the first virtual floppy disk device. Open Windows File Explorer, locate and right-click on the files or folder which is write-protected in your USB drive, and select 'Property'.
