how to resolve copying problem across network

[Ext User(shapeshifter)]

I recently installed a Western Digital Netcenter backup device drive to my
Linksys WRT54GX Network Router. However, Ive had difficulty copying around
200+ GB of data (external drive connected directly via USB to my desktop
machine) to the new network attached drive. After 15 or 20 minutes the
copying aborts with a message. Though I neglected to write down the exact
message it stated that the network drive was no longer available.

A quick visual check of the router and the drive showed that both were still
connected and operational. I've come to believe that the issue relates to
the desktop screensaver on the machine which initated the copy.

I've turned off the screen saver and the copying seems to have progressed
beyond the prior abort point. Does this make sense? What exactly is or is
not available, in terms of machine resources and in partcular network
resources, when the screensaver is invoked? Shouldn't all resources remain
available even thought the machine display is locked?


My system is WinXP SP2 with all the latest patches, PIV 2.53GHZ, 512MB Ram.
