Unable to restore any images

Hi,
I'm evaluating the Acronis Snap Deploy 3 for Workstation.

I have booted from a USB-key and I have made some image of the entire local disk C, with the Master Image Creator, to an external USB hard disk, formatted in NTFS. The image creations was fine and the program report no error.

But, when we try to restore the image, booting with the same usb key on the same computer, with the Stand Alone Utility, I got the 'poor media quality' error and the deploy do not start:
I can access and browse the the USB disk from the Stand Alone Utility and I can select the Image from the disk, I can add users or change the tcp settings and other things, but when I start the restore, the program fails.

The computer is a DELL XPS M1330.
The USB disk is a Western Digital WDME5000TE 500GB
both the hardware is NEW.

If I try to access the images from another computer, copy the images or mount it with Microsoft Vista or XP, I have no problem, so it seems that is only the linux environment of the Stand Alone Utility that have the trouble.

Any Ideas?
