Macbook Pro Data Recovery

Apple Macbook ProI have a 2011 Apple MacBook Pro (model no. A1286)
For a few months the base of the laptop had been overheating. Then the fan started to make loud whirring noises. Last week when I switched on the laptop all I received was the Apple chime noise and a blank white screen.
I made an appointment at an Apple store Genius Bar where they told me that both the logic board and hard drive are damaged. They can replace these components but are unable to retrieve the data from the damaged hard drive and have advised me to contact data retrieval specialists with regards to this.
I wonder if there is any chance that that data can be retrieved and how much is it likely to cost?

With these questions I initiated an internet search. For those of you who have never searched for anything like this before, I can tell you that there is a lot of information out there. Some sites I visited were rubbish but there were some gems in the search results. One the best was the Johnny Foreigner blog at http://johnnyforeigner.jimdo.com/ which taught me what I need to know about recovery of data from MacBooks. I must also give an honourable mention to http://thursdaynightblues.com/ web site which accurately and understandably explained to me what data recovery actually is and how it worked.

I’ve recently built up rather a mistrust of the information given at the Genius Bars. I think Apple used to try and make sure the staff who were part of these bars at least received some training in troubleshooting Mac problems, now it just seems these are populated by spotty kids fresh out of high school who know practically nothing about fixing Macs – I wouldn’t trust anything they said about data recovery.

A few enquiries to UK data recovery companies Recover Deleted Data (http://www.recover-deleted-data.co.uk/) and Computer Science Labs (http://computersciencelabs.com/) gave me a cost of between £350 and £600 for a Macbook Pro data recovery service. But don’t take my work for it, shop around and see what prices you come up with.
