Readyboost and USB Flash memory

[Schooner]

I'm using Vista and have just plugged in a USB Flash mem (Toshiba 1GB
preformatted) for the first time. I was transferring pics to the flash mem ok
until I got to around 200mb and then I received error 0x80070052 and was
unable to transfer any more pics, despite there still being close to 800mb
free on the stick.
I also noticed that Readyboost wanted to reserve 796mb for system speed but
I'd checked 'do not use this device'. (Note 200mb+796mb equates to capacity
of memory stick)

After searching on google I reformatted the flash mem as FAT and tried
transferring pics but again, at around 200mb I received the same error.

Today I've reformatted again but can now only transfer 150mb and Readyboost
now wants to reserve 850mb (though I've still chosen not to use it).

Given the flash mem is 1GB is it just a coincidence that the error message
is generated when the storage capacity of pics I've transferred + the amount
of mem Readyboost wants to reserve for system speed add up to around 1GB,
even though I'm choosing not to use Readyboost?

Any suggestions would be greatly appreciated.
Thanks heaps

After further searching on google I found someone who had a similar problem.
He fixed it by deleting everything from root on the memory stick, then
creating a folder and placing everything in the folder. I've tried the same
thing and it works ok.

Must have something to do with maximum root capacity, even though I did use
the memory stick on an older pc running Win 2000 and had no problems with
root capacity so maybe it's a Vista thing?

Since ReadyBoost is a Vista feature, then it's a pretty good guess that's
why it didn't do this on W2K.

By the way, this is a .Net programming group. These kinds of questions are
better posted to a group with "Windows" in the description. Just so you
know, for future reference.
