Chkdsk fails to run (silently); common remedies don't work

[Guest]

Chkdsk will not run on a Thinkpad T60, and it generates no error message. It
just ignores the dirty bit and an active /F request on startup. I know there
is file system corruption. I've tried every remedy I can find on the net. I
can't use recovery console because Lenovo doesn't supply a Windows CD, the
generic windows CD I have doesn't support serial ATA so it can't see the HDD,
and if I install Recovery Console via the copy of winnt32.exe on the hard
drive I get a BSOD, perhaps from a conflict with Lenovo's "Hidden Protected
Area." Here are things that DON'T solve my chkdsk problem:
/x,
/d and then /x,
safe mode and /x,
manually verifying the registry entry that triggers Autochk (the keys are
correct),
deactivating all antivirus and spyware,
The machine shipped with Diskkeeper, but I un-installed it and cleared temp
folders,
I don't have (and never had) Spyware Doctor, ZoneAlarm, Hitman Pro, etc...

I know something must be locking the disk at boot, but I can't find it.
There is no error message or event log entry - the chkdsk failure is silent,
which I guess you would say is a non-standard failure.

Ideas?

Thanks for the idea -- I tried BartPE - it created and booted from the PE CD
fine, but running chkdsk via BartPE still failed - it reported that it could
not lock the hard drive. Given that I booted from and was running chkdsk
from from the PE CD, that doesn't make any sense... but there it was. When I
take the PE CD out I can boot from the HDD normally, and the hard drive is
not encrypted. Any other suggestions?

Sorry, if there a more powerful tool than chkdsk from a pre-installed
environment, I don't know of it.
