Hello house, with due respest and in response to the complain i got from a client as a computer/networking engineer, i decided to post this piece of information to the house.
The client complained of important files on his crashed hard disk that has no back up elsewhere and if there is any possible way(s) of him getting back the files.
Yes vividly i reply to him, outlined below are the necessary steps to follow;
Firstly get another hard disk, installed it. NB:The version of the operating system on it should not be lower than the one on the crashed one.
secondly pair the two hard drive together on the same system setting the jumper of the new disk to primary master and the jumper of the crashed disk to slave.
Boot the system, by default the system boot to the new disk drive, from my computer environment navigate to the crashed drive, open it and copy the necessary files needed.

Man, I was the one that sent the post you are referred to. Thanks for your suggestion. But wait, you seem not to have understood me. I have already tried what you suggested before I sent my post. The problem is that the Hard disk was disassembled and fixed back after which the hard disk could nolonger be dictated by my operating system even when it is slaved. That is why I wrote that I feel that the hard disk platter is still ok. What I want to know is, is there any external device on which I can mount the platter from the damaged disk to read it. I have tried buying another disk of the same make so that I can disassemble that one and swap the platters, but I have not seen any to buy.

Thank you for your efforts.

the closest company i know that can handle that kind of task/retrieval is in south africa and there are lots of security measure u will undergo.
