- As usual, I'm not sure that this is the right newsgroup, but it seemed
- to be the closest match in the active file with nonzero numbers, so
- ...
-
- What I'm trying to do is write some stuff to DOS-readable diskettes on
- this Esix S5R4 machine. I even have a diskette here that was just
- stuck in a real DOS machine, files copied to it, dir run on it, and
- such nice things, which convinces me that it has a valid DOS
- filesystem on it. But when I stick it in the drive on this S5R4
- system and try the "m*" commands, I get things like:
-
- % mdir a:
- Unknown physical format or not a DOS disk
- % mcopy *.* a:
- Unknown physical format or not a DOS disk
-
- There's also the "dos*" series of commands:
-
- % dosdir a:
- read_sector(): Read error got 14 vs 30
- % dosformat a:
- Insert new diskette for /dev/rdsk/f0t
- and press <RETURN> when ready
- Formatting...dosformat: open("/dev/rdsk/f0t", O_RDWR | O_EXCL) failed
-
- It appears that there is something very badly wrong here, but none of
- the above seems to contain a clue. In fact, most of the error messages
- are outright lies. Thus, the diskette quite definitely is a DOS disk;
- a real DOS system just accepted it without complaint. As for being
- able to open the device, well, ls -l says:
-
- crw-rw-rw- 2 root sys 1,128 Nov 23 07:36 /dev/rdsk/f0t
-
- So. Does anyone know how I might find out what the @^&^%@$% is wrong
- here? TFM sure isn't much help.

- Unix trivia question of the day: What does the following command do:
