Power to 2.5 inch hard disk
Posted on 2016-11-08
A few years ago I paid someone to upgrade the 100MB 5400 rpm hard disk in my Sony laptop with a 7200 rpm 250GB drive. The old drive was working so I kept it. A week ago I noticed a portable disk case on EBay for $10 so I thought I would buy it and try to make some use of my old drive. Got it today but its not working and before I blame the old disc or new case I thought I would ask a question.
The old disc has four pins at one end that don't have anywhere to slide into in the new case. Has the design of hard discs changed such that those pins are non-existent on new drives but needed on old ones?
