Copying large files to RD1000 very slow
This is on a brand new Dell Inspiron running Windows 7 Home Pro 64bit. I use Norton Ghost to make a computer backup to an external MyBook drive and then have set the Offsite Copy to a Dell RD1000. The backup itself doesn't take an enormous amount of time but when it makes the Offsite Copy (about 46gb) it gets extremely slow. I actually haven't let it complete since it said it was going to take 23 hours to complete. I then tried just copying it from the MyBook to the RD1000 and ran into the same situation. I left it on overnight and after ten hours, it reported it was about 10% done. On my previous computer, a Dell Optiplex GX260 using Windows XP Pro, I never had an issue with this so I just don't know if it's a Windows 7 problem (although looking up compatibility, the RD1000 is supposed to completely compatible with Win7 32/64) or an RD1000 problem or what.

You could try doing NIC Driver updates on both the RD1000 and the computer your sending from.

Sounds good but I'm novice enough to not know how one does that. Would this be in the Device Manager?

Ok. I'll check that when I get home from work and get back to you. Thanks.

I checked in Device Manager and had it check for driver updates for everything in the Network folder. It did find and install one update for a "Realtek PCIe Family Controller" but everything else was reported to have the latest drivers. I also had it check for other devices as long as I was there. This still didn't seem to make any difference in the speed. Then, just to get more information, I copied a large (40gb+) from MyBook to my computer's hard drive... this took about a half hour. Then I tried to copy the same file from the computer to the RD1000 and the stats said it was going to take about 10 hours. So that narrowed it down.
Then... a revelation... I checked the wiring and found MyBook was connected directly into the pc while the RD1000 was connected through a USB hub. "AHA!", I said. I swapped some devices around and found that connecting directly into a USB port on my pc increased the speed from 756kbs to 10mbs. So I obviously the hub was a bottleneck.
I couldn't find anything on the hub that would indicate whether it was a 1.0 or 2.0 hub but, because of the speed reduction, I'm assuming the 1.0. Would you know if there is such a thing as a hub that would not restrict the flow?
