    I have a local disc drive "Q" on my brand new T4220.
    And it is somehow strange, becaus it isn't accessible. It appears in the Windows Explorer, but not in the disk manager. :confused:
    Any ideas what it is for and how to hide it on my system?

    Hi TabTom,

    NVCACHE means non-volatile cache, which utilizes either a hybrid hard drive, or Intel TurboMemory. I think the model of the T4220 you have (the T4220-02DE) comes with 1GB of TurboMemory installed onboard. There's two technologies at play here: Windows Vista ReadyDrive and ReadyBoost. ReadyDrive utilizes half of the 1GB TurboMemory (so that's 512MB) during boot up; the remaining 512MB of TurboMemory is used for ReadyBoost (similar to superfetch, used for the OS to boost performance).

    I don't know any easier way of doing it with Vista, since TweakUI PowerToys is for Windows XP only; other than doing a registry tweak to hide Drive Q from view. This is partially difficult, but make sure you read the directions fully before even attempting to modify your registry, check them out here. If you know how to count in 32-bit binary, great, this will greatly benefit you! :)

    In any case, this is the decimal you need to hide Drive Q: 4194304 - at least I hope so! :eek:

    Actually, if I'm not mistaken...You would want to use 65536, or 0x10000 (decimal, and hexadecimal, respectively). 4194304 would hide W. :)

    Thank you for the answers!

    Now I learned, that my machine is equiped with TurboMemory. I didn't know that before...

    Haha, disc Q.

    My T2010 came with a random 1GB partition named Disc D, is this the same thing?

    Hi all,

    Could you go into (maybe one could provide a screenshot) Disk Management and see if the D drive (or rather, it is known as Disk 1; C:/ is Disk 0) is titled as NVCACHE or not.

    Start -> Run -> compmgmt.msc -> OK -> Disk Management (or similar)

    --

    Are you able to access it directly, or is it similar to TabTom's situation, where it does not allow access into it?

    It could be possible that you have Intel TurboMemory, or some sort of a hybrid hard drive or storage device somewhere there.

    Hi,

    I am posting the image. Tell me if you need any more images...

    it is normally accessible but I haven't tried to save a file there.

    now I found that it has 35MB used, i think yesterday it was free but not sure. there are no files visible / can't say for hidden ones bc i don't know how to make them appear in new vista gui.

    thanks for help.
