it depends on what you're using to copy the files. Any decent backup software will give you the option of doing a read-after-write check, which means the software reads each block back after it has written it, comparing them to make sure the write was successful. It should also give a choice about what to do if the raw check fails - e.g. retry, continue, ignore - and send you a message about it, on the screen, in an email or maybe a series of cryptic beeps. You should check your copy operation thoroughly before you decide to just continue with it. I run xcopy as a scheduled task rather than backup or some other specialised software because it's simple and puts an exact copy on the backup drive rather than some humungous file in a non-obvious format, and is easy to restore.
