Totally second that opinion.
Option a)
Using a second mac (any mac with a working osx install) (or a working OSX install on
an external disk) use the target boot option at power up to select a disk to act as
the OS. ()
http://osxdaily.com/2010/04/07/how-to-boot-a-mac-in-target-disk-mode/
Once booted plug in a second new disk and use diskutility to clone (do not mount)
the broken local disk to the empty external disk.
http://superuser.com/questions/618999/osx-create-a-hdd-clone
if your local HD is removable (i.e. its not an integrated flash drive ), remove it.
and fit a replacement (usually any 7mm SATA will fit (slim 2.5'), some model will
accept a standard 2.4"(9.5mm) )
(you want to keep the original, because a clone may not pick up everything)
(if its not removable, do the clean install on an external disk)
Ps. update to SSD it makes a big difference with all OSX's >10.9. and Ext firewire
disks are solid as a remote boot option.
Install a fresh OS to the disk you are going to regularly boot from.
Use this procedure to download and copy OSX to a FLASH drive (on the other mac... )
http://osxdaily.com/2014/10/16/make-os-x-yosemite-boot-install-drive/
If you worked thought all this you should have
a) 2 working macs
1 with a clean install booting from a new disk
the spare with its original disk intact
b) a bootable USB OXS installer image.
c) your original disk + a clone (optional) which can be worked on with DR Tools to
recover files.
... now you can look into these options Or if truly valuable send the disk to a
forensics lab.
