Vista Tutorial - Can only access one partition of hard drive using enclosure

I purchased a Rockfish Hard Drive Enclosure in order to recover files from a hard drive that crashed in a Gateway laptop (OS Vista 32). I am able to only reload Windows Vista and can not repair. Drive is corrupt. I took the 120G PATA drive out of my gatway and instaled it in the enclosure and connected via the USB to anthother laptop (Dell) running Windows Visa (32). The computer assigns a letter to both partitions but I can only access the recovery partition and cannot access/explore the primary partion. Error comes up drive not accessable, parameter is incorrect. When I run the computer manager, it shows the both partitions as healthy and primary. Not sure how to get to the files I need.

Open an elevated (Run it as administrator) command prompt and type the command: CHKDSK E: /F /R /X
Hope this helps

Thanks for the reply. First ran CHKDSK without the fix, repair or dismount. Then ran CHKDSK with the F/R/X. Here is the result.

Not sure if this disk is repairable or I will have to resort to formating and then using a recovery program to try and locate files.
