External USB drive looses connection during transfer

I have win XP SP3 and a Verbatim external hard disk (1TB). During backup to
the drive or transfering of many files it "hangs" and say "Can't find the
file...". I can then still see the drive in explorer but the volume name is
gone and the size reporting 0 Byte. And it is unaccessible. When I restart it
it works again. Single file transfers is generally ok, but not many.

....and...it works quite alright in a Vista laptop so the drive itself is ok.

Solutions?

If you also used the same USB cable when you tested it on the laptop,
try a different USB port

It was the same cable and I have tested it in (2 out of 4) ports.
(Motherboard Abit AV8 with Via KT800 Pro chipset)

Driver issue (delayed write?????) or VIA issue?

I should say that I originally had SP 2 but upgraded in hope of better luck
 
USB drives generally have a throughput cap of just under 30 Meg
per second. If the drive is USB 2.0 and the computer only has a
single enhanced ( USB2 controller ) then it's likely the transfer is
saturating the USB bus ( Bandwidth ). With a single USB 2.0
controller moving to different USB sockets won't make a difference.

What do you mean by saturating the bus? I mean; why does it happen here and
not to everyone connecting a USB drive?
 
Well, if it has a loose connection, that's the first thing to look at.
All connections need to be tight and reliable so they cannot become
accidentally disconnected.

Fix the loose connection.

"Looses connection" doesn't refer to the physical cable but windows stops
being able to write to the disk.

I've tried 2 different cables and even tried to "move" the connectors while
transfering a single file but there is no connectivity problem then.

As in LOSES Connection, not LOOSES (LOOSENS) connection, huh?
