Having actually done this at several points in the past, I can assure you 
that Darren is correct.  Caching removable devices tends to be *very* bad 
for data integrity.

That's why, for example, in Windows (and on Linux), you need to "safely 
remove" USB flash drives - they are cached for performance reasons.
