It sounds like the os is performing a check on the stick.
Whilst in Vista, with the stick plugged in, right click on the stick in My Computer. Go to properties, tools and then click 'Check now' in the error checking box. Ensure all options are ticked and run the scan. Then see if the problem persists on boot. If it does, copy everything from the stick to the PC and format the stick. If it still persists,you might look at not using the stick for readyboost as the performance differences aren't usually very dramatic.
