>From your description, it would appear that the disk device has an invalid MSDOS partition table.
A work-around to this problem is to: 1) Copy any data you have on this disk device to another disk device 2) Erase the invalid MSDOS partition table. The Master Boot Record exists on the first sector of the disk device and also contains the partition table. To erase the MBR (and all data on the disk device), use a command such as: sudo dd if=/dev/zero of=/path-to-disk-device bs=512 count=1 Where: /path-to-disk-device is something like /dev/sde CAUTION: Be sure to type in the above command correctly since it will completely erase the partition table!!! 3) Write a new MSDOS partition table to the disk device using gparted, parted, fdisk, or another partition editor. 4) Proceed to create partitions on the disk device and restore your data. Hope that helps. :-) This bug has also been reported previously: [Bug 545911] Re: Cannot use gparted -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/717795 Title: Installation fails, gparted crashes. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
