Thanks for all of the comments on this. I guess I should trust flash... However, if I continue to use Vista it may be irrelevant. I might have trouble living longer than it takes to actually save to a usb device with it... Now erasing half of that 3.5GB I wrote and it looks like 2 hours to completion (and manual observation and calculation agree with that). -Skip PS I remember the days, not so long ago (before Christmas last year...), when I could copy a few hundred GB from a USB drive to a network server in a few hours. That actually takes weeks now on Vista. ARG! -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
