Simen,
Out of curiosity, that USB Hub you mentioned....is it a "powered"
hub? Have you attempted to directly connect the external USB HDD?
Thanks.

Hi all,
I'm running a pretty updated CentOS4 x86_64 server (Still on kernel
2.6.9-42.0.2, but appart from that fully up to date against the
official repos) with a USB-disk attached (the USB-disk is a 750G
Seagate disk in a Seagate enclosure) over a USB hub.
I've noticed several times that after longish periods of activity, the
disk drops out (log from last time, below). In this case, the disk
activity was generated by running two bittorrent-clients (ie random
access r/w patterns) fed by an 2Mbps connection (ie ~200kB/s
datarate). I've been able to use the drive for copying multi-GB
file-trees from the main disks (it's part of a backup project), so the
failure below seems strange, and not related to traffic.

(and multipler lines like this until the partition is unmounted).
After repowering the disk again, it seems happy, and fsck passes
without comments, and restarting the torrent-clients works well, so
the data on the disk is at least reasonably intact.
Does anyone here have similar experiences or does anyone use USB-disks
for any extended period of time?
Yours,
-S
