I had to connect the drive as a second drive on a another computer. The original computer, all of the sudden, showed a I/O error. I tried to boot with the drive on the new computer thinking it might be a hardware issue with the MB or cables, but it still shows a atapi.sys corrupted message. I do have access to all the files on the drive once I boot up with the new computer's own drive. (win 7) but, when I run FRST it gives me the log from the c drive of the new computer not my drive in question.
