ReadyBoost - Cache Exists

[Guest]

I just bought a new USB drive (4GB) and am trying to use the ReadyBoost
feature. When I go to properties and select ReadyBoost it say "A cache exist
on another device in the system". How do I find out what device? I don't
have any other USB drive hooked up. I am using Vista Ultimate.

I'm having the same problem. I received an IBM T61 and went to enable
this feature immediately and this is the message I get. I've tried
multiple USB devices which all worked on a previous Vista
installation.

When you reply to a message that is 6 months old, you need to re-state the
problem you are having. There are many ways to access these newsgroups and
not everyone can see the original message where the problem was described.

This message indicates that there is another device that has either a
ReadyBoost cache present or that it has an option to be used as a ReadyBoost
drive that is enabled.

This can difficult to find. Look in the Device Manager for any memory/drive
that is designated as 'turbo memory' or 'Ready Drive'. Look in the
properties of the device for an option to use the drive for ReadyBoost.

In the registry, you could try deleting the subkeys of:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt]

That seems to be where readyboost cache info is kept.

I have the same problem and have searched various forums for a solution
without success. How do I find out which system device another cache exists
on so that I can remove it to enable my USB flashdrive to be used to boost
the performance of my vista laptop. It used to work fine when Vista was first
installed but now I keep getting the same error message and Microsoft support
for this error message is non-existent.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt]

Also tried your solution below but there was no EMDMgmt file listed under
currentVersion

OK, after several hours of being frustrated with this same problem I finally
figured out what to do.
First, open up Disk Management (control Panel>System and
Maintenance>Administrative Tools> Create and format hard disk partitions)
Now, if your disk manager looks anything like mine, there will be 4 or 5
disks showing, one of which is called "NVCACHE." The NVCACHE is the "cache
that already exists on the system." You must delete this disk in order to
enable ReadyBoost on your other device.
To delete it you may have to assign it a letter (right click NVCAHCE>change
drive letter and name) Just give it any letter that isn't already in use.
Click OK. You will notice that If you look under Computer the NVCACHE drive
is now visible but it will not allow you to delete it from there. You must
delete it from the disk manager. To do that simply right click NVCACHE from
the Disk Manager and choose "delete volume" a confirmation/warning message
will pop up, just click OK. (Note: you may have to have Administrative Rights
to delete the volume, I'm not too sure because I was signed in as
Administrator when I tried this.)
You should now be able to pop in your USB Drive, SD card, or whatever and
enjoy the benefits of ReadyBoost.
I hope this works out for you as well as it did for me, Good Luck.

I just have to say that I've looked all over the internet for a solution to
this problem even contacted Microsoft support for an answer which they could
not provide me with, and I think it's kind of funny that I, a 16 year old
kid, figured this out when no one else could.
Sorry, just kind of a pride thing.
