Is there any programs you'd recommend for creating and modifying disk images, and writing them to disks with a USB floppy drive? In an attempt to fix this, I was hoping to find some advice on how to properly modify floppy disks using a modern computer. The convertible won't boot at all with the start up disk in now. I later tried using the Convertible's Start-Up disk in the USB floppy drive and it inexplicably added all the files that were on the DOS disk originally to this disk as soon as the drive was plugged in. I tried it in the convertible and DOS still boots but most features are missing as they were taken off the disk, making it essentially useless. Unfortunately, when trying to open the disk to copy files back onto it, I got an error, saying it wasn't formatted. It seemed to work fine, so figured I would move the entire contents of the DOS disk onto my desktop, to save a copy of the disk, and then putting them back onto the disk. I tested it by moving a mortgage calculator program (that was on the DOS disk when I got it) from the disk to my desktop just using file explorer, and then putting it back on and testing it in the convertible. I wanted to try to add/remove programs to these disks instead of having to find and buy them online. Not long ago I got a PC Convertible that only came with two disks, PC DOS 3.3 and the PC Convertible Start-Up diskette (the one with the diagnostics, intro to the PC convertible, and that you could install the app selector from. Earlier today I got a USB floppy drive for use with a modern computer.
