But as I understand it, this data loss would only occur if you were writing to the disk during an installation lets say and the power failed.
I ask because I thankfully haven't gotten the BSOD yet on my new vista install, but I did have it hang at shutdown twice and had to manually shutdown the computer (when I did this it had hung for at least 15 and there was no disk access light flashing) - do you think any harm was done if it was turned off during this period of inactivity?
Thanks for the help and it was your high recommendation of this drive that I got it in the first place - thanks!

Glad it worked out for you.
I have been running over a week and mine is working great.
No I have not tried enhanced performance.
Do you have a link to the WD site where it talks about the performance increase and risks?
You say no cash will be used, but from what I understand, less cache used means less risk. More means more risk.
Here is the example:
100 story building = 100 cylinders (each floor is a cylinder) (requires physical movement of the elevator.
Elevator = The Hard Disk Heads
People = Data be Read or Written
Maximum capacity of the Elevator = cache
Then say:
Person A gets on at Floor 1 and pushed the button to go to Floor 100.
While in route, at the 10th Floor, 50 People push the button, wanting to go back down to the first .
Without enhanced performance, the 50 people would wait for the elevator to go to the 100th floor then back down to the first floor.
With "enhanced performance" the elevator operator would make a judgment call and decide it would be more efficient to take the 50 people to the first floor
because it is closer to the elevators current location and because
"The Needs of the Many outweigh the needs of the Few or the One"
In this "enhanced performance" mode, the original person who got on at the first floor with desire to go to 100th floor, since he is buy himself, might end up riding in the elevator for quite a while before finally making it to his destination. If he was a real person he would be quite upset. But since we already said he is Data and we know that Data is an android and does not have emotions, he will understand and wait patiently.
However if Power is lost, the elevator crashes with zero survivors.
So Data runs a greater risk of being lost. Eventually when the building closes and everyone goes home for the night, Data will finally make it to his desired floor 100.
Bottom line, if there is no disk activity then there should be no more risk of g a file corrupt with enhanced performance than without.
hmmm
