In NORTON, there is this program that can change the hard disk's interleave factor. It should be for low-level formatting the hard disk. The way it works is to first read the data of the entire track, then low-level format that track, and then write the original data back. It's mainly to improve the data reading and writing speed of the hard disk. Who made us use 286, 386 back then? I think it's probably not feasible for current hard disks, and it's not necessary either!
