Exactly as I said:
An alternative would be to remove the drive from the computer it's in and install as a slave in another computer then copy the data to a flash drive or hard drive.
Power down both computers then open their cases.
Disconnect the hard drive from the problem computer and connect it to the other computer, both SATA and power cables. Make sure the original drive in the computer it's being connected to is on the lowest SATA port number, 0 or 1, depending on how they are numbered.
Connect the drive from the problem computer to a higher port number.
Boot up the computer.
Open My Computer, navigate to the just installed drive and copy off any data you want. You may have Access Denied problems in which case you will have to Take Ownership of the folders you want to get data from.
Honestly, I think doing this from the Windows 7 boot DVD is a better option with less risk of accidentally screwing things up.
