IBM Mainframe Disk Capacity Table
The following tables contain the IBM mainframe disk capacities for
all disks since dinosaurs roamed the Earth. If you know of any disks
that should be added to this table, please send an e-mail to support@sdisw.com.
If you have disk conversion issues, VM
Magic will allow you to simulate one disk type on another disk
type eliminating the need for a disk conversion. Contact sales@sdisw.com
for more information.
