Description Alberto Passalacqua 2005-10-16 20:16:03 UTC 
Data transfer from and to USB keys is very slow. It takes about 2 hours to
transfer 130 MB on a USB 2 key. It works a lot quicker in SuSE 9.3.

when you access the disk, look into /proc/mounts for the sync option:

grep -w sync /proc/mounts
Comment 2 Sebastien ROHAUT 2005-10-17 14:03:51 UTC 
this is related to bug #105871 

http://bugzilla.novell.com/show_bug.cgi?id=105871

We are all waiting for a patch to the Sync option for VFAT...

What kind of patch are you expecting?

A patch to resolve this sync problem, of course ! The hack explained in bug #105871 (for hal) works, but doesn't really corrects the problem : sync option was very fast in Suse 9.3, and extremely, very extremly slow on Suse 10.0 ...
Comment 5 Greg Kroah-Hartman 2005-10-19 22:26:06 UTC 
There is not going to be a kernel patch, this is an upstream kernel change 
to actually add support for sync to this filesystem.  The reason it was
so fast is that it wasn't doing anything :)
