OK, my drive is: Barracuda ES.2, 500GB ST3500320NS PN:9CA154-783 HP Model: GB0500C8046 Firmware: HPG1 now is having HPG6 1. I followed the steps that johnmar presented in his post here execept that my drive did not showed the message LED: 000000CC... every few seconds it just showed it once and after that the terminal locked and I can't write anything in it. 2. After LED: 000000CC... message I had to short all 4 points usig tweezers (2 by 2 not all 4 together) from the picture that johnmar posted (the two ones surrounded with red and the two ones surrounded with green) 3. Keep that 4 pins shorted for 30 seconds or more, hard drive motor stopped and the terminal was unlocked and responded to CTRL+Z command 4. Followed standard instructions that johnmar posted 5. Checked the drive to see if everithing is OK, connected to the computer in normal way and made a backup with everything from it 6. Downloaded the file that jaclaz recomended from here, tried a lot of other possibilities from HP but nothing worked because I did not had the proper hardware to run or even to install them. 7. Downloaded HP USB Key Utility version 1.7 from here, I have tried also version 1.1 if i remember correctly but it did'nt worked since I'm on Windows 7. 8. I have set the controller to emulate IDE in my motherboard BIOS 9. Booted from the USB stick, updated the hard drive firmware to HPG6 without problems. If anyone needs more support I'll try to answer as soon as I can.
