Capacity: Capacity is the amount of data that the drive can store, after formatting. Most disc drive companies, including Seagate, calculate disc capacity based on the assumption that 1 megabyte = 1000 kilobytes and 1 gigabyte=1000 megabytes.
Disks have a natural measurement of capacity based on an integral number of 512byte blocks. So kilobytes (1024) makes sense for them.
The only marketing wizardry is to use the smaller of:
1 megabyte = 1000 kilobytes
instead of:
1 megabyte = 1024 kilobytes
There are valid arguements for both interpretations.
