WD Essentials - possible data recovery after a fall?

[robusco]

Hello everyone, I wanted to ask a help: I have an external WD Essential (in the box there is WD15EADS 1.5 TB) 4 months old that I use for storage and then almost turned off. It fells down from a height of 50 cm (but was turned off and unplugged from the PC), now Windows XP does not detect it neither when I connect it with his box or if directly connected to the mobo, if I restart the computer it's detected at boot after a while, then after a minute gives an error message:
"4th master hard disk error
Press F1 to Resume"
But if I press F1 nothing happens. Pressing F2 the bios screen appears but the HDD is not detected. I realized that the disc spins because when I holding it in hand it swinging well, however when connected to the mobo I don't ear "strange" sounds and neither metal "ticks". I decided to try replacing the PCB with another identical, but a friend of mine told me that I should not resolve because I must at first extract the hdd firmware and program the new PCB. Can you help me?

Il firmware non c'entra nulla con le testine che si sono rotte. Fattene una ragione, c'e' da "operare" e non e' roba "fai da te"

Firmware has nothing to do with broken heads. Live with it as professional intervention is needed and is not a DIY.

ciao Black, ma come fai a dire con sicurezza che le testine sono rotte? anche se non si sente alcun rumore strano, nè ticchetii?

Trust him he is right. Alignment, head, motor all can be the problem in this one after a fall. He knows what he is telling your. Not a DYI job on this one.
