Hi, this post is on behalf of my father and his PC. His specs are: AMD Athlon X2 7750, Gigabyte MA770-UD3, 4GB G. Skill DDR2, ASUS GeForce 9600GSO, and a bunch of hard drives--both INTERNAL and external (C: DRIVE is a 250GB Western Digital). The computer runs XP Home SP3.

The problem is that we can't transfer large files from the computer to his 16GB Kingston DataTraveller. The problem seems to be limited to his computer, because he took both the 16GB as well as ANOTHER 4GB flash drive to Futureshop, where they let him test the USB keys there. He had put the large files on the 4GB at home, and was able to connect both USB keys on a computer at Futureshop, and transfer the large files from the 4GB to the 16GB there. He can't recall whether he transferred the files from the 4GB to the hard drive and from the hard drive to the 16GB, or from the 4GB directly to the 16GB, but regardless he is unable to do either on his computer.

We don't know the exact limits, though we were able to transfer a folder of ~24MB onto the 16GB, but individual files of ~55MB and up did not transfer. On the other hand, I was able to copy 3 folders consisting of a total of ~90MB from the 16GB to the DESKTOP without any problems.

** all of the transfers we attempted were copy+paste
When we attempted the copies, the dialogue box would pop up saying that the transfer was in progress, and the progress bar with the green blocks would show one or two blocks, and it would give a time estimate. However, the progress bar never progressed and the time estimate would either freeze or increase indefinitely.

I've tried searching for answers, and have come back empty handed. Any suggestions as to what the problem and solution might be would be greatly appreciated.

Thanks so much for your timeCan he transfer those bigger files within his computer?
Also, see, if Teracopy will work: http://www.codesector.com/teracopy.phpUSB 1.0 or 2.0?
