OK...I like the term DASD better than hard drive,,..../dasd stands for Direct Access Storage Device....used in the early days of the main frame world when the Ramac appeared as the first DASD...to distinguish it from Tape Drives which were a NON Direct Access Storage Device...... Yeah, IBM still uses the term with mainframes and the AS-400.
It logically follows that tape would be LASD (Linear Access Storage Device) doesn't it? I don't know if that's the term they actually use.
