The only things that are positively, definitely done in powers of two are things that *must* be in powers of two because of the the way they are addressed. This applies to computer memory. It does *not* apply to disk, since the number of cylinders, tracks, and sectors are not usually divisible by two. Disk manufacturers may use 2^20 as a megabyte for convenience in comparison with memory size, or they may use 10^6 which is actually more correct. They may use "formatted megabytes with 512-byte sectors" for convenience to users, or they may use "unformatted megabytes", which is the only really true measure of hardware storage capacity which doesn't change with sector size. It doesn't matter what you think the conventions ought to be. Various conventions, all of them logically justifiable, are in use regardless of what you want. Why not learn them and deal with the variations. This isn't complicated math, here. Dave
