Vista - ReadyBoost - Cache Exists

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.

multiple USB devices which all worked on a previous Vista
installation.

looking at the thread for this problem, it seems no one has an answer
just unrelated / unhelpful comments. Is any one outthere who can provide
an answer to the problem of an existing cache being used for readyboost
but a user not able to find out what is bveing used ?

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.

I didnt realise. So I can take it you also don't know the answer to the
issue of "a cache exists on another device in the system"
5 hours of attempting many suggestions from various blogs have got me
nowhere - windows life nightmare continues - joy to bill.

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.
