 Write I/O error on dosformat / doscp Hello - I'm doing some support at work for a client who's running our application on SCO 5.x Open Server. What I'm trying to do is to do a 'dosformat /dev/fd0:' or a 'dosformat /dev/rdsk/f03ht:' so I can copy a file to a floppy diskette (via doscp, of course). What I get is a Write I/O error... I've tried the following devices: /dev/fd0 /dev/rdsk/f03ht The client (they are in a different state - I don't have access to the hardware) tells me that a new floppy diskette is in the drive and that it's not write protected. I've tried my commands on a SCO box here in house and my commands work. What should I look at? I don't do much SCO stuff, so I don't really know what to look at. If this were Linux, I'd be looking at /var/log/boot.msg to make sure I had the right device and that it was detected by the OS correctly. I have tried to do just a straight 'format /dev/rdsk/f03ht:', but I get Write I/O errors on that command also. Thanks for any information or hints - I've done some Google searches, but haven't found any relevant information. I've primarily found man pages online. Best - Brian Durham      |

I've primarily found man > pages online. The man page for doscmd(C) on the SCO box should give you all the info you need. First, rule out any simple hardware problems by trying to read a DOS formatted floppy in the drive with: dosdir A: If that works, try formatting a floppy with the Unix format command: format /dev/rfd0135ds18 This assumes that you're using a 3.5" floppy drive with a 1.44MB floppy disk (two holes, one in each corner; one must be closed to write-enable the disk). If this fails, your floppy drive/cable has a hardware problem, or the floppy drive is write-protected from within the system's BIOS setup (although this shouldn't affect Unix since it doesn't use BIOS routines to write to the floppy).
