Hi
Friends
My WD400BB is making clicking and is detected as SABRE , i know it has lost firmware and is taking sabre alias from ROM.
I get techno key error 51/04 , Surprsingly i did not find much information elsewhere. Does anyone know how to come out of this problem?
Thanks in advance

Did you tried to rewrite ROM with good source?

Hi wawalab and hddlab
Thanks for your help,
I tried 2/3 pcbs of exactly same model but i got same error for all attempts , while other pcbs are working with no rom problem , i feel that rom must be ok. I dont have desoldering tools right now to replace patient rom.
Thanks

Is the clicking continuous, does it click for a while and spin down?

Hi
Friends

Thanks for your help. yes I need to recover data , at power on it starts clicking but spins normally. I swapped PCB with identical model but i get same error. Unless utility gives access to firmware we cant manipulate it. I tried ISA but no use.
I think this limitation is overcome in UDMA , those lucky guys now its your turn.
Thanks

I think may be SA head's weak, that why it's clicking. Go to kenel mode and check ROM.
