HD Failure in LVM - What can I recover?

When setting up Fedora Core 6, I mistakenly decided to continue to use this extra 30GB drive I had.

Well, the system randomly shutdown a couple of times and then I was getting the SMART error for the drive at bootup. This is my dev/hdb drive.

My hda drive has a boot partition (hda1) and a second partition (hda2) that was dedicated to the LVM Volume.

So, I went out and bought a new Seagate drive today and partitioned it as hdc1 (bootable and ultimately to replace my primary drive as well since it is getting old, too) and a second very large hdc2 partition. I then ran the commands to add it to the LVM volume. Up until this point everything was going fine.

I then used the LVM gui to try and move the data off of hdb1 and the system suddenly froze and ultimately had to be rebooted.

Now when I boot up I'm getting the following at the LVM initialization phase:
"...error creating dirty log..."
"...reload ioctl failed: Invalid Argument..."
Then a message saying that two logical volumes in "VolGroup00" active.
"...hash received Sigsegv Backtrace..."
Then some HEX codes
Then, "Kernel Panic - not syncing: Attempted to kill init"

So....My question is...Is my installation toast and should I just pull out the two old drive, leave the new Seagate 300GB in there and start from scratch? I'm just not sure how much I can get from the drives as it is.

I'm not totally familiar with data recovery in Linux... but your chances of recovering might be pretty good depending on the recovery programs available for Linux. Try not to use the drive until you have a backup program. I would take it out of the case and put it in an anti-ESD. You don't want any additional wear and tear. As long as the drive has not been formatted over and written to again, your chances of recovery are pretty good. You have to copy the contents to a separate drive, not the failing one. Alternately, contact a professional and let them take care of it.
