Re: Repair / Recover Data hard drive
Before you try anything, decide how valuable the data is -- if it's worth enough to consider professional data recovery, realize that anything you do to the drive may make it that much harder (and more costly) to recover the data. Professional data recovery costs well over $1,000 to start.
If it's not worth that (and you're willing to take the risk), give Ontrack's Easy Recovery software a try - it will tell you whether you can recover anything, free of charge. If it looks like you can get the data back, you have to buy the program, but it's a small fraction of the cost of professional data recovery.
