I upgraded to 8.04 and had problems during the upgrade. Since I had my home directory copied off I figured I could put anything I need back and did a fresh install.
Somewhere along the lines, I may have told it my data drive (pics, mp3s, kid's first steps video) was the install drive but don't think I did. Heron is installed on the correct drive now but still can't mount that old drive which I believe was originally a fat32 drive.
Is there any way I can pull the data off this drive and move it somewhere else? I tried mounting this in a USB drive enclosure in a windows host and it is unreadable, I also tried mounting it as is in Ubuntu without success. Since the stuff below is so messed, I am guessing there is no data written to the drive yet so I may be able to save it. Something along the lines of rewriting the superblock or something.
The drive I am concerned with is sdb which I believe was one large fat32 partition before.
Here is the info:
fdisk -l output
Disk /dev/sdb: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders

brad@connery:~$ sudo mount -t ext3 /dev/sdb1 /testmount/
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesg says:

brad@connery:~$ sudo dumpe2fs /dev/sdb1 |grep -i superblock

dumpe2fs: Bad magic number in super-block while trying to open /dev/sdb1
Couldn't find valid filesystem superblock.
Thanks for the help, Brad
