Good day

im new on the forum and need some help and suggestions....

few days ago my hp sas hard drive just died, night ago i used my pc normaly and a day later i couldnt boot from the drive....

as i found out the circuit board died, my hard drive is a 300 GB 15k SAS from HP (DF300ABAAA)
i found a similar hard drive, hp 73 gb 15k SAS (ST373455SS),

i changed the circuit board from the 73 gb hard drive and mine started to work again, the pc tries to access it at the boot screen.i hear how the drive gets more and more rpm's till its click few times and beeps few times, after that it just dont do anything. in the windows disk managment it shows him up as "Disk 1" with a red exclamation mark... as i compared the circuit boards they seems to be same, but i dont know does the capacity means anything to it???

i got very important stuff on the old drive... can anyone give me an advice or something, is there a help for it?

sorry for bad eng,
thanks

Wow, first DIY on SAS

my dear the case is more complicated than you think if your drive is not working
and changing pcb`s will never ever work

better to seek Pro. help the more you do it yourself the more damage will get = more $$$ extra cost

good luck

What kind of tests did you perform to determine the PCB died?

Hi
Even assuming pcb issue you must ensure both pcb's are identical. From your post patient is 300gb sas & donor pcb is 73gb .

labtech:

hmmm there wasnt any signal of the disk that its alive, couldnt hear any sound of rotations inside, and a green led (on the pcb) wasnt working, after i changed the pcb from another disk the led started to work again and the disk started to rotate....

taskmanager:
as i compared the chips on both pcb's, they where all the same, the prob is if there are diferent datas stored in his memory

hmmm ok, when i look closer at the chips, there are some differences between them...

but dunno what can i do now, its very hard to find a similar disk :/

It's easier than it seems. It's only NOT CHEAP. Anyway, all this 'experimenting' won't help.
