Does the drive have ROM?

[TerraNova]

no, ROM is embedded in microprocesssor " i think", maybe someone can confirm

[coffeebean]

you will be amazed at how compatible MHV pcb can be.

Just try some..

coffeebean...you mean any mhv pcb with same firmware will work?

[dmarques]

I got the same oppinion as coffeebean.
I've managed to recover some this way.

i have exact same firmware and i swapped over, not working still clicking.....could it be hda bad?

[TerraNova]

Hi Jose

I tried with same fw still clicking, i think the Head preamp is faulty too...

[coffeebean]

MHV - heads very sensitive.
be cautious when transplanting new heads not to "stretch" spring arms
when opening heads for insert to "ramp".

Also, these heads pick up tiny particles very, very easy and then collect
more from media.

Just check heads with microscope, if some "dirt" almost can forget it for success.
Also check profile of head surface and you can see why these heads are good at
scratching media surface.

thanks for the tips coffeebean

Is this flash ROM?

No, thats a diode. If the processor failed i am afraid it's gone, firmware on MHV cannot be matched just from the label itself. sometimes it does not work.

any other ideas gurus?
