Lost my NTFS partition
Today while in the process of burning some downloaded TV shows to DVD, my second computer's D: drive somehow got "lost". It's a 160GB with a single NTFS partition on it. Now Windows XP insists the partition is "raw". Chkdsk will not run on it because XP believes it's unformatted. Ubuntu (dual boot machine) says "read_ntfs_boot_sector(): Primary boot sector is invalid."
This drive has nothing completely irreplaceable, but a lot of stuff I would really really like to keep. Is there any way that you guys know of that would let me recover the drive? Like, rebuild the file tables in any way?
