Infinite sized hard drives (or partitons anyway)

Hi,

I'm confused. ZFS can supposedly restore any partition to any previous state... So if I have an 80GB drive, fill it with stuff, delete it all, and then fill it again, I can easily get the old 80GB worth of stuff back... So why don't they just make a format that has infinite space?

I may be wrong, but these hard drive restoration methods are designed to restore the hard drive after a file has been deleted and not written over, so although you may be able to restore an 80 gig hard drive after it has been deleted, I highly doubt that you can restore it after you have refilled with 80gigs worth of data, however, someone can correct me

I believe that's correct, although using really precise magnetic scanners or something to that effect, I believe you can still reconstruct data after it's been erased and rewritten over. Hence the 15-way zero option when you're reformatting.
