Thanks for your reply ThunderZ, but I think that my original post wasn't lucid enough so I'll try again. When I compare the two external drives' properties, folder by folder, they are identical down to the byte. When I un-hide hidden files, folders, and drives and un-hide protected operating system files then compare the two external drives' properties folder by folder they are, for all intents and purposes, identical down to the byte. And yet, one of the drives has 710,903,738,368 bytes used space and the other has 712,107,253,760 used space. To answer your question, I've never directly compared the two drives' properties-size prior to formatting, but in all the time I've owned them and kept them synchronized I've never seen this 1+ GB discrepancy in used space, and the end result of my syncing has always produced two drives with the same amount of "'x' GB free of 930 GB" according to the information available upon opening "My Computer." I think that I understand the gist of your reply, that "x" GB aren't necessarily "x" GB (due to the 1000 byte vs. 1024 byte issue), but I'm not sure how that effects used space since I've always thought that a byte was a byte.
