    USB HD bricked?

    I just used ubuntu's Disk Utility to format a multi partitioned hard drive.

    The "format" seemed to go "well" ... except I didn't see any lights flashing to indicate any disk activity. Nonetheless I seemed to have ended up with an empty disk.

    HOWEVER, it will NOT mount with ubuntu.

    The log stops at "Attached SCSI disk".

    I seemed to read that such not-mounting problems are not uncommon and the best (easiest?) way to fix 'em is by mounting the drive on a microsoft machine and doing chkdsk. Fair enough. A Windows machine (MS7 if it matters) gave a friendly beep when the HD was plugged in and, in a pop up, told me that the "new hardware" had been installed ... but it is nowhere to be found.

    Anyone know how I can get over this? I'd like my drive back.

    TIA

    I would try gparted, which from a Ubuntu install, needs to be installed to look at the HD, gparted can also be downloaded as a bootable disc as well, and is on the live Ubuntu cd.

    There are a number of partitioners that run in windows as well you can look on the web for them. Perfect disc the free download is one I often use to move all data to the front of the disc when doing windows partition size changes, it runs in windows and has some nice tools.

    Thanks for taking the time to respond,

    As far as I know I cannot use gparted if I can't mount the disk. If gparted is usable with an unmounted disk please tell me how.

    As for partitioning, in fact I do NOT want the disk to be partitioned. Sorry for mentioning that it was before and, I guess, throwing you off track.

    I suggested gparted and other partitioner’s as they may give you a clue as to why you are having problems.

    ... but ... how do I get gparted (or any other utility) to access the drive?

    Sorry, our messages sort of passed in the night there.

    fdisk gives:

    Disk /dev/sdc doesn't contain a valid partition table


    Presumably my "problem" is /dev/sdc. Sure hope you know what to do about it ...

    Re: USB HD bricked?

    To clarify, disks aren't "mounted" - only partitions are. Gparted works with partitions on a disk, and it can simply be used to view the existing partition structure not change partitions. It doesn't matter if there are any partitions on a disk or not - Gparted can still "see" it if registers as a drive. If a partition is already mounted it will flag an error if you try to manipulate it.

    Gparted is a useful, helpful tool to have on hand.

    But instead of Gparted, try fdisk. Open a terminal and type this:

    Code:
    sudo fdisk -l
    and post the output of that here.
