has anyone tried readyboost with a flash drive with that u3 junk on it? I've installled vista on a slow box but it generally works great.. ( although i do get spikes of cpu usage @ 100% and i can't seem to figure out why -- even when i'm doing something cpu non-intensive )

in any case, when i put in the drive(2GB sandisk cruzer) my cpu goes up and somtimes it'll stay at 100%. If i'm not doing anything it's around %30 for the system process. once i take it out, goes back down.


My boss gave me this drive a few days ago so i haven't had time to play with it yet.  I'm going to try killing everything on the drive but i was wondering if anyone faced something like this before
