well, in the last few years, i've upgraded my hard drive a few times, and i'm wondering about something.
all the files started on a 20gig drive, moved to a 100 gig, then to a 500 gig, then to a 750 gig, back to the 500 gig, eventually to a 1 Tb and in the next few years it will probably move some more.
so i'm worried, when i move the file, does it slowly corrupt the files? and eventually it'll be unreadable? or does the computer usually do a perfect copy and i have nothing to worry about?
