It is a different chemistry at the write layer. John W.

Are they just fooling us by not freezing the file allocation table, deleting what we wrote last time but not recovering the space? And if not that, how do they manage to rewrite locations that have already been written to? IOW, if I almost completely fill a disk, then delete everything, then change the date of the source files and recopy them to the disk, will there be room? If so, how do they do it?
