USB3 with Shadow Protect getting error trying to write to drive

I was wanting to use USB3 in my VM's to run Shadow Protect.  I have been able to get a sucessful backup on a physical machine running XP Pro, but on the same PC booting to shadow protect it fails with the error 31, to write to disk.  It is the NEC USB3 CHIP. In the VM I am able to move data across the drives, so the from my guest 2008 to a USB3 drive, and get transfer rates of around 50-60Mb/Sec, but when running shadow inside the system it fails again when writing to disk.

What permissions or registry settings would I possibly be looking for.....Shadow Protect boots from CD and loads the OS, the USB drive is physically attached so not shared....so not sure what you think I should look at!

If I understand correctly, you are booting with the Shadow Protect Boot CD and trying to take an image of the physical drive which ultimately fails because of the NEC USB3 Chip.
You are running Windows XP Host OS and which a Windows Server 2008 VM is running.
Please correct me if I am wrong.

OK I have a physical XP Pro machine, that I can do a shadow protect IT edition(SP) from when I am within the OS.  If I boot to SP, load the NEC driver, I get a failure.  However i can browse to the USB drive, copy data both directions and it is fine.

I also have an ESXi4 server with a Server2008 inside, that can see the USB3 and i can copy data to and from(avg speed 50MB/Sec)...however as soon as I try to use SP it fails.  I have yet to try and do this with the server shutdown, and use the SP Boot load driver and run...though that is next.  I am also bringing the std USB2 controller on line to see if it is all OK.....it worked before when I did a SP restore.

Storage Craft have nothing to say on the issue..just they don't support USB3 yet...hmm thanks for that!

Well, if the application does not support writing to USB 3.0 Drives then I am sure it would not work.

OK it works like a charm in Server2008 x 64.  Get speeds of 150MB/S from usb3 drive to VM server, ans SP backs up at 60Mb/S
So i think it is a driver issue, that needs to be resolved
