    Re: USB HD is there but not mounting

    ok i think we might be getting somewhere,

    i have been been changing some of the syntax and come up with this

    Code:
    paddy@paddy-laptop:~$ sudo mount -t vfat /dev/sdb /media/Myfiles
    mount: /dev/sdb: can't read superblock
    i tried to mount it with sdb1 but it doesn't exist

    my guess is its not being recognized or is not reporting itself to the os. Have you tried rebooting with the drive plugged in? Also, look in your log files under /var/log/ for any reference to the hard drive. The dmesg, syslog, kernel.log could be worth a look.

    Beyond that, I really have no other suggestions other that trying it on another computer to see if its even working. If it fails to mount on another computer, then I'm afraid you may have a dead hard drive. Sorry.

    well seeing how its an external disk, try removing it from the enclosure and installing it in a desktop computer. If its fairly new, less than year, it might have a sata interface. Therefore, you need a pc that has a sata power as well as a sata power plug for it.

    Check this out if you don't know what it is: http://en.wikipedia.org/wiki/Serial_ATA and an older disk may have a ide conector, that just looks like a long bar with a bunch of pins (about 40), it takes a standard 40pin connector but you will need to set the junper to master or slave.

    So, if that fails. Then, you truly have a dead disk. Sorry for your loss.

    shame it was a good disk storing everything until the end.

    Re: USB HD is there but not mounting

    I'm having a very similar problem, and have reproduced it with two separate disks on two separate computers.

    Both disks worked fine with ubuntu until they were not "safely removed" under windows XP. After being unsafely removed, neither would mount under ubuntu.

    fdisk -l indicates that the disk contains a valid vfat partition at /dev/sdb1, dmesg indicates that the disk was configured and set up as sdb1, however the device /dev/sdb1 does not exist.
    /dev/sdb exists, so ubuntu is detecting the disk, but failing to detect the partition.

    I've replicated this on jaunty with both a WD Passport and a patriot 8GB thumb drive.

    Both disks still mount fine under windows XP. Cleanly removing them under XP does not change their behavior under ubuntu.

    I have not been able to find any other reference to this bug besides this thread...perhaps its time for a bug report?

    Godspeed
