Capacity of a hard drive

[dougevans]

How do you calculate the capacity of a multi zoned recorded hard drive from the cylinder allocation table (Zones, Physical Cylinders, Sectors/Track and Heads). The cyliners * heads * sectors/track * 512 method used with non zoned drives does not work.

Thanks

Sorry about the last message. The old formula of cylinder * heads * sectors per track * 512 still works if you apply it to each zone and then total up the capacites. The problem was not the formula I employed, it was that I actually beleived the data I read in one of the widely known hardware reference books. The next time I shall double check any data with the manufacturer.

Thanks anyway.
