my laptop's internal harddrive is a bit slow. I looked at the drive properties and there are two options:

[X] Enable write caching on the device
[ ] Turn off windows write-cache buffer flushing on the device

As you can see, the first option is checked already, but the second option isn't. I've heard the second option can really speed things up, but it also sounds very risky. Is it safe to do on a laptop that rarely is off of AC power? (but still has battery as well)
