Yep, the old seagate drive is kaput. Having removed it from the enclosure I had an idea. After a bit of a rummage I dug out a spare 2.5″ drive I had left over from a MacBook drive upgrade. Both that and the dud drive had the same SATA interface so I thought, why not?
10 minutes later I had a perfectly serviceable network drive ready to go. It’s nowhere near as big as the old one, either in capacity or physical dimensions, but it will come in handy as a shared drive for odd storage jobs.
Now all I have to do is take the dud one apart before it goes to the Council tip for recycling.
