Vista mis-reading USB Flash Drive

[mavalpha]

This is a 1GB Sandisk Cruzer Micro (U3 Edition), from which I've removed the U3 feature. I wanted to use it for ReadyBoost, but Vista says:
"This drive is only 120MB, you need 256MB for ReadyBoost to be available." (Or something to that effect.)

Any thoughts, or just feel like laughing?

Back up the G: drive, delete that partition and create a new one taking up the whole disk. That should fix it just fine.
