unmounting a floppy (moronic newbie question)
Boy, learning Linux is fun. Today I used (copied from) a floppy for the second time! Took me all of ten minutes with CP/M, but with Linux. . . . mount tells me (inter alia): /dev/fd0 on /media/floppy type vfat (rw,noexec,nosuid,nodev,sync,user=peter) Having copied from it, I no longer want it. I'm not using it (as far as I know, and I've thought about this for some time). peter@linux:~> umount /dev/fd0 brings me the message umount: /media/floppy: device is busy Can I just ignore this and take the silly thing out before it fries? (I'd like to return it to its owner.) (Yes, I have attempted to look in the user guide, the unofficial FAQ, and one O'Reilly book about Linux to see how a diskette can be busy when it appears not to be in use -- no results.)

You have the directory /media/floppy open in konqueror or, perhaps, an xterm window, something is using /media/floppy. Close that app or leave /media/floppy directory and it should no longer be busy. and the command is: umount /media/floppy -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org

No, I'd thought of that before I posted. But just for good measure I closed down everything (even Mozilla, which I've now reopened for this message) other than the konsole, and tried again, this time using umount /media/floppy This gives me the same bull about the device being busy. As for an xterm window, my Linux book doesn't describe what it is in sufficient detail for me to understand. (Funny, I always thought my IQ was over 60 until I started to use Linux three weeks or so ago.)
xterm is like a windows command prompt window in your window manager, except that it is running a unix/linux shell. make sure you do cd / or something to make sure you are not in /media/floppy

This is the same problem with CD drives too I think. You're using 8.2 correct? If so, open kdesysguard, and kill all non-root instances of kio and/or konqueror, and you should then be able to umount your floppy. Then in control center, you might want to uncheck that konqueror has 1 instance of it 'ready' (it won't be any noticeably slower to open, YMMV).

Rohit tempts me:
I always just take out my floppies...
But why do something so simple when instead I can follow John, who correctly surmises that I'm using 8.2 and
pen kdesysguard, and kill all non-root instances of kio and/or konqueror, and you should then be able to umount your floppy.
Done. Man, that was fun. I don't know what kio was, but I had a great time zapping all of its instances.
Then in control center, you might want to uncheck that konqueror has 1 instance of it 'ready' (it won't be any noticeably slower to open, YMMV).
MM (my mileage) is all over the place as it is. My Control Centre is in Japanese, but the likeliest thing is [what I back-translate as] "Internet & network | Web browser". But I can't see anything promising under that.
I needed fresh bugs for my SuSE gecko, and Linux penguin. So I went out and caught this huge ugly blue and red and green and yellow butterfly.
Hmm, I could make some slightly different observation about the apparent relative bugginess of 8.2 and Win2k -- but that would merely exhibit my ignorance, so I'll desist.

You can kill them all in one go by using the command:
fuser -k

Dont worry. Two bit [actually free] but reputed internet tests tell me that my IQ is 148 [showing off] but then I am so dumb that even this question did not occur to me. I always just take out my floppies...

lsof /media/floppy should show what is using the device. Ken

I often get that message, cannot unmount floppy, device is busy. When in an X-terminal, I close the terminal, open a new one, then I can unmount the floppy. When in a text console, I log off and back in again, then I can unmount the floppy. So, the device being busy appears to be the terminal...? SH

Only *if* sometime after mounting the floppy, you cd'ed into the floppy and did not leave. The terminal would be ?focused? in the floppy and would not allow you to umount. If you are riding a horse, do not kill the horse. You would no longer be riding. You would get off and onto another horse *first*. Not a good analogy but you get the idea <grin>. -- Patrick Shanahan Registered Linux User #207535 http://wahoo.no-ip.org @ http://counter.li.org

Try this "lsof /dev/fd0". This should tell you what is keeping the disk from being unmounted. Give it a try -- Marshall "Nothing is impossible, we just do not have all the anwsers to make the impossible, possible."

Hey, at least: cp original destination make more sense than pip destination=original ;-) Charles -- lp1 on fire (One of the more obfuscated kernel messages)
