Windows 7 - Help with Seagate 1.5 TB 7200.11 not found on BIOS

It wasn't until my 1.5 TB Seagate 7200.11 storage HDD died last week that I found this enormous info on the web about a possible malfunction that rendered these 7200.11 drives useless. Also read about a firmware update released by seagate to fix this problem.

Now going back to last week, I was working with my pc and the drive worked as well as always, then I took it out from the case because I wanted to place it in a new build but the silly me somehow pushed the drive with my elbow while it was on the table and it fell down, performed a couple of spins and finally rested on the carpeted floor. It isn't recognized in 3 pcs so far, not even in the BIOS.

I've read in some forums that you can recover the stuff on the drive by making a usb or serial cable, connecting it to the little pins on the drive and running some commands on a terminal (i.e. Hyperterminal or Putty). This procedure is for 7200.11 malfunctioning drives.

I will try the method described above knowing my drive probably died from the fell and not from a bad factory firmware, but at this point I'm trying anything.

Do you guys could recommend me something else to get the stuff I had on this drive?

Thanks for your time.
