Kingston DTI/2GBFE

I can offer a suggestion or two. In order to tell if the problem is the flash drive or the computer, try attaching it to a different computer, and test it with similar file transfers.

If it behaves the same, then it is probably faulty. There's only a slight chance that running a Check Disk on it will improve things. (in My Computer, Right-Click on the flash drive, then click on Properties, then the Tools tab, then the Check Now button).

If it seems fine on a different computer, then try attaching it to your own computer on different USB ports. In particular, do not attach to a USB hub, but directly to a front or back port. If you are successful in finding a good port, then consider the previously used USB port to be faulty.
