HDD not recognizing in Win7 or Vista

Specs: Windows 7
I have a Pexagon Store-it that is currently not recognized by Win7 or Vista, and I am afraid I have lost my important (to me) family photos and less important iTunes. I have been scouring the web all day for a solution, and want to explore options before attempting a recovery with a disk recovery company.

Troubleshooting I have done:
Rebooted both machines I have tried to recognize this on.
Went into Device manager and disabled each USB hub controller to make sure each was fresh, and rebooted.
Rescanned for HW changes several times
looked for this device in each of the device manager tabs, including hard drives, usb controllers, and all other sections where something changed between rescans.
Power works fine on the device, it looks like some send/receive function must be working because the front of the machine does blink occassionally.
Tried every port on every laptop in my home (3 different laptops, with Vista, or 7).
Been to Hitachi HDD tech support site.
Been to PexagonTech support site.
Read all the FAQ pages on each of these sites.
Searched for similar problems, most people can at least see the USB holder.

What I have not tried (yet):
Opening the case and removing the actual HDD from the enclosure to try a different enclosure.
Called one of the main data recovery companies.

Any advice on utilities that could help me recognize whether it is my laptops not recognizing it, or if there might be some sort of circuitry short between the actual HDD and the USB enclosure?

Any other suggestions on what to try to get this recognizing?

Again, lights on, can hear the HDD spinning, can see the HDD drive light blinking every 5 seconds or so... but no sign of life at all on any of the laptops...

Thanks in advance!!

USB devices may not work correctly when they're connected to certain USB ports. Instructions for how to re-load your USB stack in 2000 or XP - similar applies to Vista and Windows 7.

In addition, all external drives connected by USB require that the port (or ports) they connect to can actually supply 500ma of current.

USB external hard drive requirements.

Another common problem is that the drive may have a corrupt FAT table. An easy way to determine this is through Disk Management....

Right click on my computer and choose Mange
Click on Disk Management on the left hand side

If the drive is being recognized at all by the computer it will appear in the lower right hand window pane. It may show as Disk 1 or Disk 2. The key is to see how it is showing up, if it says anything other than Healthy this means that the drive is not appearing with a drive letter because the FAT table is corrupt.

What to do next....

Since the content appears to be important to recover you should be able to find a simple inexpensive software to perform the recovery (Flashfixers.com or Mediarecover.com for example).

If the data is not important and the drive can be formatted you can right click on the drive listing and choose to either Delete Partition (Then Create Partition) or Format, depending on the condition of the corruption. Hope this helps.
