    One of the first things I do on my new installs, is head over to the Device Manager and enable disk caching and enable advanced performance - however for some reason on the 1420's 7200RPM HDD it says "This device is does not allow its write cache setting to be modified"

    Does anyone know why this is the case? I was able to do this on my E1505 and all other Windows machines like, ever...

    I experienced the same with my D630. Settings were either greyed-out or wouldn't keep. In either case, a fresh install "fixed" it. After some reading, it may have had something to do with Intel RAID(?) controllers, or some HDD driver related to the Restore feature on factory-fresh Dells.

    I wasn't adventurous enough to mess with HDD controllers on a functioning system, so I waited until my new hard drive which warranted a reinstall. I now have write caching (and agressive write caching) features available, and running it on all drives.

    Good luck.

    Ya, but both systems have two different kinds of HDD's (same driver though) and tons of installs on each...but I just want it to work! In my experience, it does give a performance boost...so why wouldn't I want it to work?

    Is this for Vista only? I also have the 160gig 7200rpm drive in my 1420.. But i'm now using XP on the machine, if I can help by checking under XP, let me know.
