I have two small USB flash drives, 64 MB and 128 MB, normally used
for temporarily storing a few small files. Today I copied a dozen
files totaling 42 Megabytes to the 64 MB drive on my Fedora Core 3
box and was astounded to find it took around 45 Minutes. I tried
it with the 128 MB drive and the same job took 15 Minutes.

By comparison, the same copy job to the 128 MB drive under either
Windows XP or my old, slow Red Hat 9 box takes about 15-20 Seconds.

What could be wrong on the FC3 box to make it so slow? It's a
3 GHz Pentium 4 system with USB 2 ports. The Red Hat 9 box is only
a 450 MHz Pentium 2 system with USB 1 ports.

On the FC3 system, the flash drive automatically mounts when plugged
in and the entry: /dev/sda1 /media/usbdisk vfat
pamconsole,exec,noauto,iocharset=utf8,noatime,sync,managed 0 0

appears in /etc/fstab.

Try removing 'sync' from the fstab line.


I would also update to FC5, as FC3 and 4 are both EOL'd and are only now
supported via the Fedora Legacy folks for security and bug fixes.

There have been notable improvements in HAL and udev since FC3 was released.

BTW, RH9 will be without any support beyond the end of the year, with
final bug reports accepted until October 1 via the Fedora Legacy folks.

HTH,

Yeah, I realize that. But newer is not always better. I've kept
RH 9 because I have a few apps which haven't been updated and don't
work on later releases. I probably will update my FC3 system to FC5
in the near future - I have never gotten FC3 working to my
satisfaction (or at all) in several areas where FC2 worked fine.
(And FC3 worked in other areas where FC2 didn't.)
