comment How to mount/recover data on a disk that was part of a mdadm raid 1 on another machine?
I tried 63*512 without any luck. I tried a variety of other offsets as well. 4096 gave the best results. I used fsck and it told me that it had reverted the disk to a ext2 system since the ext3/4 was corrupted. It then went on to attempt to convert the entire disk to ext2 (I believe so) since it was saying inode # has illegal blocks.... I aborted and switched over to foremost after that. I may have lot some of the data at the start of the disk - I'll find out soon. >.<

@Gilles Seems like I'm stuck for the moment. I've posted a hexdump if it may help anyone. I'll continue looking into this on my own as well to see if anything comes up. I'm still open to suggestions too!

@Gilles I'm currently trying to mount the disk on Ubuntu 12.04. It is a fresh install as of 2 weeks ago and I only use it for coding. I think it is more likely that the disk is messed up somehow. I can vouch that the disk is not encrypted since I had originally setup the software raid. Is it possible to force mdadm to pick up this disk and rebuild a RAID array? Or does it seem that it is too much trouble at this point?

I cannot be completely sure the disk wasn't written to since it last worked - it was in the hands of someone else and I'm taking their word. See the update in the original question for the output of the commands.

The deep scan turned up the same results as the quick scan: No partitions found. I can't see anything to go on as far as testdisk is concerned. Not sure what to do at this point. All suggestions so far have led to a giant wall >.<

After running an analysis on the full disk, it turned up no partitions. Currently running a deep scan now. If this doesn't turn up anything, I'm not sure where to go from here.

testdisk is completely new territory for me. A basic run (Analyse) show No ext2, JFS, Reiser.. marker. Bad relative sector. No partition is bootable. It also provides the following: 1 P Linux 0 1 1 121600 254 63 1953520002 How can I make sense of that in order to help the situation?

Running e2fsck /dev/sdc1?offset=2048 (I also ran offset=1985) outputs Bad magic number..Superblock invalid... as well as suggesting that the superblock is corrupt and trying to run e2fsck with an alternative superblock. Seems like I should provide it an alternative superblock to move forward.

@Gilles A mdadm -E /dev/sdc returns the following for me: /dev/sdc: MBR Magic : aa55 Partition[0] : 1953520002 sectors at 63 (type 83) but no information for /dev/sdc1 though

mdadm -A /dev/sdc1 outputs mdadm: device /dev/sdc1 exists but is not an md array. I've gone a bit further to use mdadm and see if there is any additional info... mdadm --misc --examine /dev/sdc1 outputs mdadm: No md superblock detected on /dev/sdc1.. Is there a way that I can re-write the superblocks on this disk to mark it as an available disk for RAID assembly?

The force mount doesn't give any errors, but the mount point is blank. Either the data is gone, or the mount didn't work as expected. Doing a df shows me that the newly mounted disk is 2% in use which is significantly lower than expected.
