- I've installed Linux about 20-30 times, and every single time the filesystem
- ends up corrupted when I use some floppy-related command like tar(with /dev/fd0
- as file, pax and GNU tar alike), dd, fdformat...
-
- This is the diagnostics of recent dd session(under 0.97 patchlevel 4):
-
- # dd if=/dev/fd0 of=foo bs=8192
- floppy: Drive 0 is write protected
- floppy I/O error
- dev 0200, sector 848

- 180 + 0 records out
- /lib/libc.2.2.2
- linux login:
- <Ctrl-Alt-Del-reboot>
- #fsck -a /dev/hda1 # My root(and only) partition
- Block nr. X marked not in use
- .
- . # I guess as many times as blocks in 'foo'
- .
- Zone x: not in use, counted = 1

- Could it be my hardware that is stabbing my back? 386BSD and MINIX works
- fine though.
- I will be infinitely grateful if someone can help me with this.
-
-
- I must emphasize, though, that in every other aspect Linux works great.
