Fedroa 10 Wedges File System under heavy I/O Load



From time to time I back up data from /u, /y, and /var onto
an external IDE HD attached with a USB interface as /dev/sde1.
The command used is:  cd /; find u y var -print | cpio -pmd /b
This has worked well until recently.

Now Fedora "wedges" the /u file system at some time during this
backup process, which takes about three hours.  If /u doesn't
wedge before the backup finished with /u, the backup runs
to completion.

Strangely enough, even when /u is wedged, other file systems
on the same drive typically work normally.  Commands such
as sync and ps -ef wedge, but df does not.

Any ideas what to look for??
