I got the three RedHat Linux 2.1 floppies written using #RawWrite #rawrite on #WindowsNT4 on the 1996 #IBM #Thinkpad, but the first ramdisk floppy was bad. I'm using a stock of floppies individually sealed in plastic since 1998. Taking a fresh one, I formatted it to (waves hands) refresh the magnetic material and was able to write a valid image and confirm it was correct using an md5sum binary I found at https://www.pc-tools.net/win32/md5sums/
