    Floppy USB drive failure.

    I am having problems mounting the floppy USB drive. "Places -> Computer" sees an icon labelled "Floppy Drive", but it cannot see any files on the disk. "System -> Administration -> Disk Utility" sees "Floppy Drive" with "Connection: USB at 12mb/sec". The thing that is different is that the last screen mentioned also sees "Device: /dev/sdb" with "Capacity: No media detected". I am new at this and cannot figure out how capture a screen shot of the Drive Utility page. While back at "Paces -> Computer -> Floppy Drive -> Properties" there is a entry:"Location: Computer:///" which do not agree. What should I do?

    Press Print Screen and you should see KSnapshot, or something similar pop up, you can then save the image.

    Having a vague stab in the dark here... When you plug the USB in, do you end up with a notification? Does it ask you to install any drivers? (Have you got a diskette in there? )

    If not, try looking through this thread: http://ubuntuforums.org/showthread.php?t=1066686

    There is no notification. And, no, it does not ask me to install any drivers. Of course I have the disk in the thing.

    I have looked at the above listing. I have over 35 years of computer experience in general and would like to keep the professionalism of this inquire a little higher than you give me credit. The problem is that I have been bereft of all my coding capabilities ever since DOS became obsolete. No, I am not published, just retired like many others.

    Waiting for someone to truly help me with this problem. I need access to my disks.

    Hopefully, when I install Ubuntu 11.04 (beta) this problem will be solved.

    When we see an initial posting, especially in this forum, we have no way of knowing the poster's experience level, and so we tend to start out at the lowest common denominator. Since you have extensive experience with MS-DOS, it'll be easier to help you!

    Linux, unlike MS-DOS, has a clear distinction between the data physically stored on the disk, and that same data as it exists in RAM where the system can deal with it. In MS-DOS, it would have been like differentiating between the disk data and the buffer in which it's stored. MS-DOS hid the distinction, but Linux requires that explicit action be taken to move the data between the two areas. That's done by the "mount" and "umount" commands. At boot time, some drives are mounted automatically in defined directories (mount points) but others can be added later.

    My initial guess, since your listing from lspci shows the drive's attributes, is that the device is being detected properly but is not being mounted. To confirm this you can issue the "mount" command by itself to get a list of all mounted devices. First, though, use the command "sudo fdisk -l" (that's lower-case L, not the numeral 1) to get a listing of all detected devices. One of those listed should be the floppy, with a name similar to either "/dev/fd?" or "/dev/usb?" where the "?" is a numeral, probably 0. Then look for that same name in the results from "mount" -- it probably will not be there.

    Post the results of both commands and we'll be able to tell you how to add the device to the automount listing. And don't be too disappointed if the move to 11.04 makes no difference at all. Use of floppies is so rare these days that many of the newer kids on the block don't even seem to know that they exist!

    BTW, if you remember a book from the early 90s called "Undocumented DOS," you may recognize my name. It's good to see another veteran of those days and before!

    Re: Floppy USB drive failure.

    Great! Your floppy is /deb/sdb and since floppies do not have partition tables, the error message and partition information for it are meaningless; they don't indicate any serious problem.

    However, it's a puzzlement as to why the system is detecting the floppy as a SCSI drive (the "sd" prefix in the assigned device name) and this is probably why it's not mounting.

    Try unplugging the USB cable and rebooting, to make sure that the system doesn't detect any "/dev/sdb" device, then plug in the USB cable and see whether the drive shows up within a minute or so. I've had to do this with some devices; the auto-detection code that runs at boot time is a bit different from the hot-swap USB code that runs when a new device gets plugged in, and that sometimes makes a world of difference.

    If it doesn't, try these commands in a terminal window, with the USB cable plugged in:
    Code:
    sudo mkdir /media/floppy
    sudo mount -t msdos /dev/sdb /media/floppy
    Once the /media/floppy directory gets created you don't need to run mkdir again, of course. Hopefully this should make the floppy's files available in the /media/floppy directory, although you probably won't be able to write to them because of permissions conflicts. We can handle that with automounting code, if this works to give you access, but first let's find out which approach works best...

    Hopefully a few others will pitch in here with ideas as to why the floppy is being detected as SCSI (or at least as a hard disk, since recent releases of Ubuntu have treated all hard disks as SCSI). Once that is cleared up, the floppy details can be added to the /etc/fstab file and you should be in good shape.
