    Readyboost lost other drives

    I installed Readyboost from a 4 gig USB "Cruzer Micro" Sandisk USB flash drive. This drive is now set to use 3 gigs of the four for improving the Ram on my 4 gig Dell, Vista computer. The Readyboost installed fine but now I don't see the drives that are used for camera's flash cards. None of the slots for Compact Disk, SD, mini, XD and MMC work. When I look at Explore, I see drives C, D, E, J and K. Drives F - I, which were used for the camera's cards, are missing.

    Thanks.

    Re: Readyboost lost other drives

    And....... ???

    I assume you want to know how to get your missing drives back, yes ?? Have you tried uninstalling Readyboost just to see if the drives come back ???

    One other consideration from here.... "Windows uses different drivers to connect to Plays For Sure devices, so they canít be used with ReadyBoost."

    Re: Readyboost lost other drives

    I tried uninstalling Readyboost and I removed the flash drive. Now all I can see is C, D, and E. C is the main drive. D is the recovery drive and E is the DVD drive.

    Sounds like you are not going to be able to use Readyboost. <img src=/S/frown.gif border=0 alt=frown width=15 height=15>

    Re: Readyboost lost other drives

    Have you tried a system restore to a time before you messed with Readyboot?

    If I'm reading your configuration correctly that you have 4GB RAM, Readyboost will almost assuredly not help you. See ReadyBoost - Wikipedia, the free encyclopedia for a definition of Readyboost. Also, see AnandTech: Windows Vista Performance Guide for performance analysis.

    Re: Readyboost lost other drives

    There is a useful site for ReadyBoost information at GrantGibson. It is worth remembering that an SD chip can also act as a ReadyBoost device for any computer that has a slot for one, so long as the SD is suitable. It took a long time before there were many genuinely compatible ReadyBoost drives available. Because you are using a U3 drive, you end up with two drive letters for the device. ReadyBoost devices have a learning curve: so long as you are using it on a given computer, it will learn your boot sequence with repeated use, and become increasingly effective up to its limit.

    I am using the same kind as yours, and interestingly I have the same problem with having a lost drive letter for a slot, but until your post I had no idea how I might have got it, so I shall follow this with interest.

    Yes. I did a system restore to the day before I ran Readyboast and it was no help.

    Re: Readyboost lost other drives

    Do any unknown devices show in device manager? Anything with a yellow question mark?

    Re: Readyboost lost other drives

    Yes. Under "Other Devices" there is something called "Logitech BT Mini-Receiver DFU." I don't have any such device. I tried uninstalling but when I rebooted, I got the message that this device needed a driver. When I checked the Device manager again, the Logitech device appeared again. I tried to download a driver but Windows could not find one.

    So now, I guess I have to find a way to get rid of this?

    Thanks.

    Re: Readyboost lost other drives

    I am happy to report that I have fixed my own longstanding problem with a missing drive letter for one of the four slots I have, and it might help with whatever went wrong with yours. In my case it appears that a virtual drive had taken over the drive letter that the slot previously occupied. Getting it back was a lot of work, at least in terms of time consumed, but for all the hassle I am happy to have it back.

    Something that is seldom mentioned in forums is that software no longer comes with a wheelbarrow full of fat books because it is far more efficient to store the books on the hard drive, and help needs are more efficiently dealt with because they are searchable. Microsoft's online tutorials are very useful, and the links are there. In other words, the first place to go for help should be Help And Support from the Start menu. (No kidding. A lot of users don't even know it's there, or don't think to look, and it is constantly being improved.)

    If you go there and type 'Drive Letter' the first of the first thirty results (Change, add, or remove a drive letter) will take you to Computer Management and the directions for that may help solve your problem. They definitely solved mine.

    Re: Readyboost lost other drives

    Do you have a Logitech BlueTooth Keyboard or Mouse ??

    Other forums have threads indicating that it might be a faulty bluetooth dongle. <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15>

    No. It's all Dell. I shouldn't have this Logitech device. Nothing "Logitech" is attached to the computer.

    Re: Readyboost lost other drives

    Very strange. I'm afraid I have no idea. You might take a lokk at this thread on another forum. It suggests a couple different possibilities to remove the unwanted or non-existant device.
