how to recover formatted truecrypt partition

Hi, recently I did a factory recovery on my lenovo laptop and I did in an unusual way, I did the recovery from the Windows XP rescue and recovery dvd (originaly there was a Windows 7 OS on my laptop) and I was kinda suprised that the recovery process formated the entire physical drive instead of just C:\ (system volume).

Thing is that there was one small truecrypt partition (E:\) with a valuable data on it and now I want to get it back! I am looking at the drive in some recovery software, I can see all the data from my data volume (D:\) and they are just ok but I do not want to touch the drive in any way till I get the idea how to recover the truecrypt partition.

I was already checking this site and found this https://www.experts-exchange.com/Storage/Hard_Drives/Q_23780932.html but it was of no use to me. The Norton Disk Doctor is really hard to find and it's functionability is, I guess, outdated. I also found out that from functional point of view programs such as GetDataBack and TestDisk are not for me at this point. Besides the question on that link is concerned on truecrypt volume that spanned the entire drive, which is not my case here.

The biggest problem here is that during the factory recovery process the drive was not only formatted but it also installed a new copy of windows XP, so, some files may have been overwrtitten (looking at the drive through, for example, GetDataBack, shows that the majority of files is still rescuable) and there is a new NTFS volume that span the entire disk.

So, my question here is how do I recover that truecrypt partition ? I am not concerned about anything else what was on this drive. Thanks.
