Problems with copying from Server 2003 to USB drives : hanging / crashing?

Hi

I'm having trouble copying from one of my servers (an HPDL185 running Windows Storage Server 2003) to USB drives.  What I am trying to do is set up some replication copies of my backup folders (I'm using ShadowProtect) but the problem is not related to SP itself, nor it's 'ImageManager' but to the actual speed of getting to the USB.

If I use the software (ShadowProtect OR dos OR robocopy or Explorer drag/drop the symptoms are the same - trying to copy large files to USB (my example is a 17gb file) is at best painfully slow and at worst, impossible.

the symptoms are :
(using robocopy as an example, but the symptoms are the same with other apps)
the initial speed is okay, the first 10-20% of the file seems to go quite smoothly, but then it drags on at about 0.1% every few seconds until it eventually grinds to a halt - or sometimes it stops for about 5 MINUTES before starting again.
Sometimes this will 'hang' explorer and effectively the whole server - until I pull the USB cable, I cannot click on or run any other apps as they do not respond to mouse clicks.

When using Shadowprotect’s own ImageManager to replicate, the symptoms are similar (starts quick, stops) but occasionally I get a ‘buffer timeout.’ Message.

This makes using USB almost impossible.

For the record, I have tried 4 different USB drives of various sizes (1TB, 2TB, 3TB etc) and different manufacturers, some powered, some not and some without any manufacturer firmware. the symptoms are always the same.

So… what’s at fault here…. Server Hardware / Windows  or what?

Removed the "Outlook" Zone and replaced it with the " M$ OS", "M$ Server", and "Hard Drives & Storage" Zones.

Copying >2 GigaBytes at once is not reliable with Win2003 explorer.
Give a try to a replacement sw like SuperCopier

I understand that but I highlighted an example of trying dos, robocopy etc as well as the original software (ImageManager) which is intended for just this purpose.  I'm guessng there could be a hardware issue somewhere, but I need some clues to help reule out Storage server 2003 as the problem, and then whether I'm talking about an actual hardware fault (Usb ports) or inability to push through data, some sort of buffering issue or something.
