So I have performed a complete wipe of the laptop, formatted it, did a clean install of Vista Business. Installed all the drivers, added all the hotfixes, Windows Updates, etc.
I then stopped all non-essential startup items, so that only these startup:
AD Monitor [fingeprint related service]
AuthenTec Fingerprint Service [fingeprint related service]
Data Transfer Service [fingeprint related service]
ThinkPad PM Services
InstallDriver Table Manager
On Screen Display
Why is it, my hard drive accessing light constantly blinks. I've left my computer on for a few hours, come back, and it still blinks once a second. Why is the hard drive being accessed so much? Is it a specific driver? I could only assume that's got to be some wear on the ball bearings, I never had this problem with my T60.

Most hard drives have now switched to fluid bearings for the disk spindle. I don't know what sort of bearing the actuator head pivot has, I assume simple sleeve bearing? In any case, the hard drive activity is unlikely to prematurely wear out your drive. Unless you're noticing user interface slowness or battery drain or bothersome noise caused by the hard drive activity, you can safely ignore it.
On the other hand, if you want to track down what's causing the hard drive accesses, some of the tools from Sysinternals may help. In particular:

Hmm.. I'm more or less just curious what's causing it? I've already disabled the indexing service.
I checked Process Explorer, but how can you tell what's accessing the hard drive? It shows 99% idle services for CPU.

Was your optical drive shut down from the lenovo powermanager?
I have the same problem with OCZ Vertex.
If the powermanager shuts down my optical drive, the HDD-led is permanently on.

Have you tried turning down the level on the Think Vantage Active Protection Software?
We had problems with this software when it is set to High, the hard disc light was on constantly making the laptops (T400's imaged with XP) very unresponsive.
Once we turned down the level to Medium they were fine.
