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
