Why won't readyboost work on my flash drive?

Question

ive got a Patriot Xporter XT Extreme 4Gb which are listed as one of the best drives for vistas readyboost

but the option is not showing up.

do i have to format it?

if so what type fat32 or ntfs?

Answer 1

you should check if it's ready boost compatible by clicking right open properties and there should be ready boost check field ( I have AData and it's FAT32 format ) . I know it will sound stupid bur are you using Windows Vista ?

Answer 2

I've got a Sandisk Cruzer which had to formatted in NTFS before it was recognised as Readyboost capable.
