I'm curious why that icon is appearing for USB thumb-drives under XP anyways? If the drive's "write cache policy" is set for "optimize for quick removal" (in other words, write-caching is disabled for the device), then it should be no problem (in terms of device data-integrity) if it is removed, as long as nothing is actively writing to it. (Many USB flash drives have write-activity LEDs on them.) OTOH, any applications that may have the file open (for read), may crash if you yank it out without closing the file. Most apps aren't that brain-dead though.
