Re: Trying to access my hard drive
Sounds like the hard drive has been damaged beyond repair. The write head has probably been damaged. There are moving parts within the hard drives that if damaged, can only be recovered by completely dismantling the drive and reading the platters with special equipment.
Depending on the amount you are willing to spend, I would chalk this up as a lesson learned in backing up your files on a regular basis and move on. Professional file recovery can cost upwards of 600 dollars.
One of the many examples of why you should backup files at least once a week on removable media. File corruption, destruction, virus's, etc can destroy all of your files within seconds.
