Cannot Query State of drive problem. How to Unlock Drive

I have a HP Touchsmart TX2 laptop that starts to boot then fails.
I've tried to use the restore console, both from the recovery partition and the distribution disk, but the only thing showing on the screen is the mouse pointer.

I tried to add the hard drive to another system (VISTA 32-bit) as a slave with marginal success.
The recovery partition (drive M:) shows 1.47 GB free of 12.4 GB.
The other partition (drive K:) doesn't show any statisitics of usage or availability in either Computer or the Disk Management within the Computer Management.  (in fact the Disk Management takes a long time to load with this hard drive connected.  (connected through a SATA to USB 2.0 adapter, standard practice for me adding an additional drive to this PC)
The disk management eventually finds drive K: and shows 453 GB RAW as the file system format.
I see on the Internet that there are utilities for recovering RAW partitions, BUT..

This drive was originally formatted under Vista, then upgraded to Win 7 using a "Qualifying upgrade" DVD from HP.

What do you recommend I do ?  

Which utility do you think would get the RAW system file converted back to NTFS based on this upgrade path?  (Hopefully a FREE utility)

As long as you don't save using TestDisk you'll be OK.  Use TestDisk to check your partition tables.  See if there is a partition table for K:

That'll give you an idea of what is on the disk or if you should try and restore the missing partition table.  TestDisk may be able to see any files on K: as well.

The disk may also be failing.  Check the manufacturer's web site for diagnostic utils and run over this drive.

Sounds like a good tool and I have downloaded it to try it in the future
