Item too big

I just used my passport model wd2500 to copy data from an old computer and transfer it to a new one.  It copied the old file fine, but when i tried to synch to the new machine, i got multiple "item too big to copy’ messages.  I don’t understand how it coudl have sucessfully copied the files from the old computer, and then failed to move them to the new computer.  I didn’t copy down the error number either.   can someone tell me why this happens? also, is there a log file anywhere of the files that were affected? thanks

The internal hard drive in your computer, do you have it formatted in FAT32?
