[Solved] Partition Table Messed Up?

My secondary partition on my Windows 7 laptop recently disappeared. I ran Norton Partition Manager to see if I could format a messed up external harddrive, and when NPM started it reported errors and asked if I'd like to fix them. I did, and since then my D drive has been "missing" from My Computer.

Computer Management's Disk Management console sees the partition, albiet with out an assigned drive letter, and when I try and assign one DMC reports that it is "out of date" and needs to be refreshed.

I've used gpart in ubuntu 9.04, to no avail, although Ubuntu has 0 problems reading the D drive. It shows up with 0 problems and copying to/from the partition is no problem.

I tried to run spinrite on the drive, however after the screen where you choose to run either mode 2 or 4 the program 'searches for drives' forever, which is weird. When I run gparted in Ubuntu, it reports that "partitions cannot run outside drive size" or something along those lines.

Anyone have any suggestions? I know I could just recover the data from the D drive via Ubuntu and then recreate the partition, but I'd rather not spend the time copying data since it is obviously all there still.

Thanks
