Having had 2 trial external hd cadies fail, both were silent, one started and shut down as soon as the dc power plug was inserted, then as the data matters to you. My advice is buy a reasonable caddy with lots of good refs from amazon. Also check how many bad reviews it had.
Unlike the above advice - and I am not saying either is right or wrong.
My experience with a pro hp laptop was when first booting up, it just clicked.
There were 3.brilliant techies, all 3 said it was us. I think they said the hard disc controller was finished.
As there were contracts worth over £8M on there, they swapped the disc to 2 other laptops - no sucess.
The sort of good news was the data was recoverable from a specialist company. Think they said these people " mount" the disc on a universal controller. It was a straight drive so no caddy to confuse the issue.
BTW the companys auto backup system, had actually got everything. So it was never proved but the specialist company charged a small fee, to determine if it could be recovered, and then if you went ahead guarranteed the rest of the fee plus the investigative fee if they could not "materially recover the majority of the data" So they were not con men. And one of our chaps said one of the clients had a fire and thry got back 90% of the data.
The bad news is if I remember the trial fee was £200 and the actual recovery was another £500 and that was a few years ago.
My bet is its the caddy. So maybe £20 will do it.
My bad experience was with ones that cost about £9 - imo too cheap.
