Flash drives have a limited write lifetime. The amount differs from
10 000 to 100 000. Every time you write access time to a sector it
shortens the lifetime of this sector and thus of the flash drive.
With an mp3 player for more than 200 Euro and a 1GB xd card for my
digicam my preference focuses on lifetime :-).

Do you really need access times on a flash drive especially under
those circumstances?

Thanks! I found the corresponding .fdi file and hope to find time in
the next days to understand configuration.
