We need to see if images on a hard drive that does not respond can be recovered. Search shows that there's a number of companies offering their services but would appreciate any vendor specific recommendations from others who may have had to go through this.
 
There are levels of "does not respond":
  1. Can't boot from it, but the computer otherwise does not report errors.
  2. The computer reports "no disk".
  3. The disk makes loud clacking noises.
  4. In addition to #3, there is visible smoke and/or sparks.
If the situation is #1 or #2, have you tried reading the disk with another computer? Putting in in a powered USB (or equivalent) enclosure and seeing if another computer can read it might work.

#3 is bad news, the drive might not be recoverable at all. #4 is very bad™

Assuming you can't read it on another computer, and there is no visible smoke, the only thing you can do is send it to a professional outfit that does forensic level recovery. Ontrack (now "Kroll Ontrack") has historically been the big gun in that industry. I have used them in the past, they are expensive but if the data is on the drive they can recover it. I have also heard of SalvageData and TTR Data Recovery, but I have never used them.
 
If the drive does not appear to have hardware problems, but shows no files or data, try SpinRite at grc.com. It does an OS-independent exhaustive set of reads and rewrites to recover the maximum possible amount of data if there are damaged areas or sectors on the disk.
 
Thanks for the input. Basically it justs died. No visible/audible clues before one day it just didn't show up (Win 7). I've tried different computers & docking devices with no luck. It does act like it's starting up when connected, but is not recognized by the OS. No "loud clacking noises" either.

Looks like the major recovery outfits offer a free estimate but the cynical side of me realizes I'm more or less at their mercy. Not unlike a mechanic giving an inflated estimate to that "little old lady" who doesn't even know how to open the hood. :)

But seriously, I assume outfits such as Ontrack are more reputable than that.

Some years ago I successfully recovered the contents of a 'seemingly dead' laptop hard drive by freezing it. Instructions can be found here http://lifehacker.com/5515337/save-a-failed-hard-drive-in-your-freezer-redux , or just google 'freeze hard drive'.
 
Quite a few years ago, in business, I used these these guys http://www.vogon-investigation.com/index.htm so they've been around a long time.

They are definitely at the heavy end if the market (they recovered the Kuwaiti royal families data after a raid on their archives!), but since you don't mention your location they do operate internationally.

If the drive does not appear to have hardware problems, but shows no files or data,
The problem is that it doesn't come up in the OS. Simply not recognized.
SpinRite works at the sector level, not the OS level, so not a problem if the hardware is functioning. It has it's own OS. In fact that's the type of situation where this program works the best. If the BIOS sees it, SpinRite will see it.

For $89 or so it's a lot cheaper to try than a full recovery service.
