Truecrypt and Invalid Partiion Table... ug.

Hello all,

I have a truecrypt drive. I lost a mobo and had to swap it out. Upon reinstalling my two drives, I installed them reversed from the previous setup. Then I tried to reinstall xp. Well, xp likes to install it on the first drive. That was my encrypted drive. I did NOT format but I believe the xp setup decided to overwrite the partition table. Hang on, it's gonna be a bumpy ride.

I first went into the Computer Management and the drive is listed as dynamic and foreign.

In Computer Management, this is what I see....
(Besides Disk 0)

Disk 1 (with the warning exclamation point)
Dynamic
Foreign

If I right click on it, I get three options:
Convert to basic disk
Properties
Help

If I click on Properties, I get the properties info dialog box with four tabs. The "volumes" tab has the following information.
Disk: Disk 1
Type: Dynamic
Status: Foreign
Partition style: Master Boot Record (MBR)
Capacity: 0 MB
Unallocated Space: 0 MB
Reserved Space: 0 MB

Does this help?

I used winhex to examine the drive. I saw a couple text error msg at the beginning with "Invalid Partition Table" "Error Loading operating system" and "Missing operating system".

Also, at the end of the drive it has a bunch of very specific 00's. It has a few bits of data but most are 00's.

Lastly, there is a huge section of 00's at the beginning and eventually goes to actual data. Not sure how to see if it is at 32000 (or whatever) though. I have the offset view. I clicked on it to see the decimal but that didn't do anything. I used xp's scientific calc and found that 7e00 (where the data begins) is the 32256 in dec, exactly what I were looking for.

Does this mean that the xp setup rewrote the partition table and my data is still there? I have seen users use testdisk to recreate the partition. Would that work? Anyone have instructions on how to do this?

I used testdisk to get some info on the drive. Does this help?

Anyone have any info please? This is a lot of data and no I don't have a backup. It is a tb of info and I don't have the space to back it up.

Anything can help.

Thanks!
