I have a floppy disk that is formatted in an unknown format. I have tried to mount it with all the options i can think of,without any luck. The disk is readable by the original machine. The original machine is a cnc mill with a boston digital controller. They no longer support this control and would not elaborate as to the file system or the format. I'tried to just dd the disk to the hard drive, but get an input/output error.
Any help would be appreciated.
