Picture transfer problems to/from USB attached devices

I too am having similar problems. I have an Acer Aspire E380 with AMDAthlon 64 x 2 Dual Core Processor 4200+ 2.20 GHz. It happens when i try to import pictures from my Sony DSC-V1 camera (read action). it also happens if I try to save a picture from Internet Explorer onto a USB extermal drive (write action). The files immediately corrupt when I try to save. The common denominator appears to be transferring to/from external disks attached via USB. Not sure whether it's an Acer driver issue or Vista.
