Hard-drive corruption question

I have a hard drive that stopped functioning when other hardware was added
to the system. I ran diagnostics from the manufacturer website which said
nothing was wrong. I have added that drive to three other computers as a
primary or slave, or in an external USB case. Each time the computer will
not boot past the intial windows flag screen, and BSOD shows errors in
ntfs.sys. If I boot to any non-ntfs boot disk (like the diagnostics) the
computer does not crash, but any ntfs disk (including the Windows CD)
crashes with the BSOD. I downloaded an ntfs reader which in a crude
DOS-like format shows that the files are still intact, but I don't know how
to view the file system and replace ntfs.sys without booting to ntfs which
crashes the system.

Is there a utility out there to replace ntfs.sys without booting to ntfs?
The ntfs reader will only copy from NTFS to a FAT partition, so I can't copy
from one ntfs drive to the other in a 2 drive system.
