I currently discovered a problem when using the floppy drive /dev/fd0: I can't use it. I can mount /dev/fd0 as normal, can create/write a file, but it is not written to the floppy disk. Instead of that the current program (eg vim) hangs (or is "uninterruptable") until I remove the floppy disk from the drive. Because of the removal I get several errors in /var/log/messages. What I'm doing:
== snip ==
mount /dev/fd0 /mnt
echo "TEST" > /mnt/test
sync [--> HANG until I remove the floppy disk]
[sync "completes"/terminates, insert floppy disk]
umount /mnt
== snap ==
(In this example I used echo instead of vim, because it behaves the same in this situation) The errors I get are as follows:

so i have a limited user (my dad) on Jaunty who has no write access to his floppy disks. Nautilus gives a permission denied error, and i discovered that root owns the floppy drive, thus allowing his read-only. (that write tab on the floppy in on btw). However, when i login as a admin, nautilus says that user has write access. ??? I check the user's user privliges and everything exept "administer the system" is checked. I can copy files on it by logging in as root.

OS: Windows XP
Virtual Machine: Bochs-2.4.5
I want to learn some details about linux booting, so I begin writing a small boot program myself. Yesterday, I was writing a small boot program and planned to use it boot a Bochs virtual machine. The boot program is written in assembly language and compiled with nasm.I use bxiamge.exe in Bochs and create an floppy image called boot.img and configure the Bochs virtual host to boot from this floppy image. My question is how to write the compiled boot.bin program into the floppy image(boot.img)?

I have a computer with no floppy drive (x64 ubuntu lucid installed) I have a program (wine windows xp) that will only save data and export data from/to a floppy drive. I found information on setting up an emulated floppy drive. i.e.
sudo dd bs=512 count=2880 if=/dev/zero of=imagefile.img
sudo mkfs.msdos imagefile.img
sudo mount imagefile.img /media/floppy -o loop
I modified the winecfg to include under the drive section A: /media/floppy. Problem is I cannot write to the drive as a normal user. I have tried everything I know but only root can read write to the drive. Is there someway to set up this emulated floppy to allow me as a user to write and read contents.

Is there something weird about the FLOPPY DRIVE on F12? Nothing associated with it works & I can't get an icon for it. Also the FLOPPY FORMATTER no longer works. (mine is an internal drive)- I had some really miner quirks with it in 10 but it worked. I had some workaround launchers that I used until an upgrade semi-fixed it. (It would give a false error that it couldn't run but did. I just ignored it.)
I tried to edit FSTAB to cure a problem of my BACKUP drive showing up twice*** so while I was in there I added the stuff for the floppy & it still doesn't work. If I try to mount it manually, I get the error that /dev/fd0 doesn't exist.I tried to find some info on it & it SEEMS that there MAY be a bug but I'm not sure as the info is a bit confusing as to just what version & such they are talking about. And there was also the problem that all the stuff seemed to be OLD or not related to my problem.I why I quite hacking at my system, is that all my workaround launchers & the formatter say that there are GNOME things missing & they can't run. So I figure that there is something missing or screwy already & that I'd better ask BEFORE I make things worse or actually break something.With the fact that floppies are about gone, it's getting to be not that big of a deal but I still find myself having to use them for repair purposes (albeit, not as much) & it gets to be a bit of a pain to fire up M$ just to do something like this.
*** It appears that the one in FSTAB was the one I needed, so where would the OTHER one be so I can get rid of it? Or at least make it auto mount.

I am having a Promise TX4650 RAID controller & trying to create a driver floppy for installing the drivers. Also am using RHEL 5, I can create the driver floppy, but when I type "mount /dev/fd0 /media/floppy" I get error: "mount: mount point /media/floppy does not exist".Can I get the files in a format other than the ext2 floppy image, so that we do not need to use a floppy drive?There is a readme file inside the driver archive & you can use that as a reference.

I have a laptop with a floppy drive, and it works fine in Windows, but I'm not sure how to use it under Linux. It does not show up in PCmanFM, like my USB-harddrive, but I do have a /dev/fd0, so I tried:sudo mount /dev/fd0 /mntand then it complains about the file system not being specified, so I dosudo mount -t vfat /dev/fd0 /mntbut to no avail.

I have an external usb connected floppy drive that I cannot mount.#fdisk -1 does not show the drive, in my ignorance I thought that it being a usb it would be recognized the same as flash drives and my external usb ide hdd are recognized.The drive does work, I have tested it in windows computers.Does the floppy need special settings?This may be related or it may be another issue totally:The floppy is recognized in gparted although I cannot format the disc to fat16 or fat 32 as they are greyed out.

Just installed 64 bit Squeeze on a new build system Athlon quad core 3 GHz and 4 GB of ddr3 in a Gygabyte GA-870A-UD3 rev 2.1 mobo and I can't mount the floppy disk. The onboard controller is an ITE IT8720 chip. The floppy is a generic internal drive - Sony I think.I know the hardware is ok as various versions of Puppy linux mount and unmount it ok and.When I saved I got the message "Unable to mount floppy dev/fd0 is not a valid block device" editing back and saving got "Unable to mount floppy0 dev/fd0 is not a valid block device".Can anyone point me in the right direction?

I scored a Dell poweredge 6300 from a local pawn shop. It has the capability to boot from cd-rom, but apparently not with isolinux, which is what the debian installer cd uses. I was able to boot to UBCD411 (Ultimate Boot CD, which uses syslinux), but didn't see any option to boot to a CD (maybe I'm missing something here?). I tried using the boot floppy from this site. I didn't expect it to work (it's from the Woody era), and it did not. I got a message that says SYSLINUX ver.XXXX CBIOS boot failed. I went to [URL].. and looked for a boot floppy image for Lenny, but apparently it doesn't exist. I did however find the boot floppy image for Etch.
To be honest, even if I did find the Lenny floppy boot image, I'm not sure how to use it to point the system to the installer CD. So, I have two questions:
1) Does anyone know of a boot floppy image for Lenny, or if I could use the Etch boot floppy image?
2) How would one boot from floppy, then point the system to the installer CD?
System info:
(4) Xeon Pentium 2 processors 500 Mhz
(6) UltraSCSI hard drives
(1) SCSI cd-rom drive
(1) SCSI dvd-rom drive
(1) Floppy drive
(1) 10/100 NIC
I'm open to any other suggestions as to how I could install Debian Lenny on this machine.

I am trying to configure my test Squeze install on an older PC with LXDE desktop, and I can't seem to find anything which would enable me to mount a floppy.Then I tried to use the konsole as root mount -w /dev/fd0 /media/floppy0
But although this device and this mount point exist, nothing is mounted. I double checked with various floppies which I know have data on them and none of them are being mounted. The umount command would I expect be umount /media/floppy0 /dev/fd0...I tried searching the web and this forum and didn't find anything helpful. Can anyone help?

The task is to create a TrueCrypt file on a buddy's USB HDD and copy a bunch of my stuff to the file. He runs Win7 so disk has NTFS. He has data on it that I don't want to compromise. Disk then goes back to him to run under Win7.The disk automounts just fine. Here's the mtab line:/dev/sdb1 /media/OneTouch440Plus ntfs rw,nosuid,nodev,uhelper=hal,uid=1000.Read (as user) is no problem. It looks like I should (as user) be able to write to it but I can't. Permissions show user as owner but read-only and can't be changed by owner. I've tried an fstab entry and mounting from CLI but no luck. I have not tried to manipulate the disk files with chown/chmod out of concern I might compromise other files on the drive.

I want to use dual Monitor on Debian Lenny amd64, I have the nVidia 8600 GTS. I googled several times, I have to change the xorg.conf (as it seems) but I can't - no rights.
And there's another thing... I have a dual boot system along with the openSUSE HDD but I can't open it. And using openSUSE I can't read or write on the Debian's HDD. How can I change that?

I have a Western Digital "My Book" on my network which I have mounted with cifs.
If I go into it and vi a file, all is fine. I can write and save and close. When I open the file and add to it and then try to write it again, I get the message:
"thefilename" E212: Can't open file for writing
The file is owned by me still and the permissions are -rw-rw-r--
I don't understand why it works the first time and not the second. Also this same effect is observable when I save from another program to there. The first save is fine, the second can not be saved.

I have a USB stick, formatted as FAT32 and I assumed that everybody would be able to read from and write to it. However, I find that if more than one person is logged on to the machine (logged on locally, with "Switch User"), then only one of the users is allowed to write to the stick, and the other users are only allowed to read from it. Is that normal?
Here's the scenario: person A logs into the machine, is in the middle of something but gets called away and the screensaver kicks in. The screen is now locked. Person B comes to the machine to quickly copy a file onto a USB stick, doesn't know person A's password so does a "Switch User" and logs in as themselves. They plug in the stick, can read from it, but can't write to the stick at all. Permission denied.
By doing a "ls -l /media", person B can see that the stick is mounted but is owned by personA with permissions drwxr-xr-x . So only person A can write to the stick. I haven't done extensive testing but it seems to be the person who logged on first who gets to own the stick. It's certainly repeatable as described above. And it's really annoying, because unless person B knows the root password, he can't write to the stick. As a real last resort person B could reboot the computer but he doesn't know whether person A has any important stuff open or not.
