Connect both host ends of the cable to different USB ports so that the drive gets plenty of power, and use a tool with built-in reliability such as rsync to actually perform the copy.

If you are copying from between drives on the the same system or to a file share try teracopy -- http://www.codesector.com/teracopy.php

If you're using Windows 7, Vista, or XP, Microsoft has a fairly full-featured free utility called SyncToy which could probably do the job.

It's a "smart" file copier in that only copies files which don't exist on the destination or are older than the versions on the source, so if the transfer is ever interrupted for some reason, it can be restarted and will resume where it left off.

There are a number of other, similar file "syncing" programs available, both free and not, for Windows as well as most other Operating Systems. One well-know free ones for *nix system's is called rsync.
