When it is attached to your desktop machine, can you feel if it is spinning? When you say that the desktop does not detect the hard drive, is that in the bios or when you open my computer? If the drive is recognized in the bios, you can purchase software like getback ntfs that will try to reconstruct the fat table so you can copy items over to the desktop's hard drive. You can download a trial version that will let you know if it will work but you would have to buy it to actually transfer the software to the desktop's drive. You can also try to download the manufacturer's drive certification test that will fix bad sectors and some minor problems. Spinrite will try to recover data for each sector that may have weak bits set (not completely up or down). If the desktop does not see the drive in the bios, the circuit board on the hard drive is bad or the drive is not spinning. If you carefully hold the drive in your hand and slightly twist the drive you should feel a gyro effect from the spinning drive. If you do not feel the drive spinning, the motor is probably bad or the motor circuitry on the bottom circuit board of the hard drive is bad. Sometimes (maybe 50%) you can try to replace the circuit board with the exact same model circuit board (even if you buy the same drive model, they can have different circuit boards). The problem is the newer drives have a flash chip that stores tweaks to each specific drive for accurate access and speed. If the exact same circuit board spins the drive but can not read well, you will have unsolder the flash chip and move it over to the new circuit board. Then the chances get better for recovery. If the new circuit board will not spin the motor, then the motor is bad. You would have to send the drive to the manufacturer or some recovery company that can remove the platters and mount them on their equipment, calibrate it and read it (probably $1000+ with no guarantee). There are some people that post how to smash out the old motor and replace it with a new one but I think it would be a mistake to try.

I would try to do the install over again but enter the HP utilities by tapping F10 until the HP utilities come up and run the hard drive test and the memory test. I am thinking you have a memory problem.
