I have bought my S10 a week ago, and having the same problem. While copying a whole album from a hard drive, system transfers several files, and then hangs up for a while, then continues again, than again hangs. Sometimes device even disappear as disk drive and this produces copying error of course.
This happens regardless of copying method ether by Explorer/Total Commander or by iriver plus 3. Upgrading firmware to 1.05AU didn’t helped.

This is really annoying thing. Please Help!

Actually I don't want to play with USB settings in the BIOS, since I have many other USB devices, and all of them are working perfectly.

Another strange moment, that S10 doesn’t detected as a disk drive when connected through a straight USB extension cable. But charging still appears on the screen.
Again all my other USB devices (transcend flash, IrDa, Sony N1 Camera) are working correctly through this cable.
