WD2500JD-22HBC0 after pcb swap shows as WD2000 08.02D08

I had determined that i had a burnt hard drive that made the clicking sound.

I read the internet a especially these forums. I found this topic western-digital-pcb-swap-rule-t8951-20.html and decided to buy another hard drive with a similiar PCB. As it appears, the disk ain't working. There's still the clicking sound, but it's different. And the hard drive is even recognized by BIOS as WD2000 08.02D08(donor HD identified properly as WD2500JD-22HBC0), compared to the burnt PCB which was not recognized by BIOS.

After trying to swap the PCB with no luck, I came across the info of switching the ROM. Is this really necessary?


Sorry for the noobines.

yes necessary .

Absoloutely.

The orginal problem, was it constant clicking or click-click-click.....spin down?

So the ROM is the Samsung made chip(similiar here, although it's RAM: http://media.photobucket.com/image/sams ... re/ram.jpg)? The orginal problem was click-click-click and no recognition, now it's a click and then a longer pause then click again. The old PCB has several burnt chips, mainly the "smooth" -chip. CPU is not necessarily burnt, but it does have a mark of melted foam. All the chips have definitely been running hot once. The smooth chip has burnet quite heavily. Lastly there are two smaller chips(resistor size) on the edge, that have burned quite seriously. Other chips look fine.

What and where is the ROM chip located?
