All HP** Firmwares have disabled terminal access. To reach terminal on these drives you have to download another firmware update from Seagate website and update the drive.
To make the drive reach readinnes you must unscrew the logic board, connect cables, switch on power supply and wait for hard drive readinnes. Then, put the logic board back to drive and launch firmware update.
To make the process safer, you could also unsolder the ROM chip and read its dump from a programmer device, then solder it back to logic board.
