Hello,

I use Rsync successully to sync, for example, a NTFS formatted WinXP PC
(where Cygwin's Rsync runs) with a Linux PC, and to sync the Win-PC with
a <n> GByte USB memory stick.

When the memory stick is formatted to NTFS all works fine (exact command see
below please).
But since I formatted the memory stick to FAT32 because it's more usuable on
Linux PCs, suddenly the very same Rsync command shows different results! It
copies many files from the Win-PC to the USB stick which already are up to
date...
I couldn't figure out what these files have in common... or why Rsync would
get wrong information from the FAT32 filesystem...

In the end I tried the Rsync parameter "--checksum" which solved the problem,
but slows down the whole thing a lot.
Then I found the "--update" parameter which does the trick, too. OK, so it
prints many directories which "--checksum" did not print, but ... it's rather
optical.

The command is :
* rsync --delete --update --relative --recursive --times --progress
Sourcefolder/ /cygdrive/u/Destinationfolder

Using parameters like "--owner" or "-permission" didn't help.

Does anybody know what is the problem with FAT32 (and Rsync using it) ? Thanks.

-Richard
