Guest Graaben Posted October 25, 2008 Posted October 25, 2008 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

(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
Guest R. McCarty Posted October 25, 2008 Posted October 25, 2008 Re: External USB drive looses connection during transfer 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.

I mean; why does it happen here and not to everyone connecting a USB drive?
Guest Twayne Posted October 26, 2008 Posted October 26, 2008 Re: External USB drive looses connection during transfer 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. > I have win XP SP3 and a Verbatim external hard disk (1TB).

"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.
