Restore partition table or recover data


I was putting the cover back on my Antec p180b, and I guess it got stuck and gave it a hard bump (pretty much broke the cover). As a result, one of my hard drives, a Seagate Barracuda ST3750640AS, got messed up or something. All the other hard drives are fine. It's in an LVM with another hard drive, so now I can't boot up into my computer. So I booted into the installation CD:

Code:
# find /dev/sd[a-c][1-3]
/dev/sda1
/dev/sda2
/dev/sda3
/dev/sdb1
# find /dev/sdc*
/dev/sdc
This led me to believe the partition was messed up. So I ran cfdisk, and it said something about a missing partition table or something. Additionally, instead of showing the single partition on it, it displays, from my recollection, Pri*Log. To my knowledge, this is the only problem with the hard drive.

So now I need to either somehow create or restore the partition table without overwriting the data. Or get a new hard drive, and some how recover the data (LVM, partitions, and all).

Partition recover usually means testdisk to me - certainly a good starting point. Even handles LVM these days.
I presume you are aware that an entire device can be defined as a single LVM extent - in which case there will not be a partition at all. Depends how you defined it.

Well you still need to create a partition, but it would be an LVM type partition. At least that's how it would be stored in the partition table. I'm checking out testdisk now.

I stand corrected. Didn't know you could do it that way.
