Hello, I have a maxtor diamondmax plus 9 who suddenly (after a restart) stoppet to be recongnized by the BIOS. The platters do not spin anymore and the Smooth chip in aprox 3-4 seconds become very very hot ..
I borrowed a maxtor diamond max plus 9 80 gb YAR41BW0, 6Y080L0422011 ,S.N. Y28J3DHE, F4FYA (Calypso III) and I put that pcb on my hdd (DiamomnMax Plus 9 120gb, YAR41BWO ,6Y120L0132611,S.N. Y3PYZD3E, M6FYA) .
The platters was this time spinning , but it also started clicking .
After I've read some post of this forum I discovered that the preamplifier connector has almost 0 ohms betwen +5 v -5v and GND pins . Because my hdd still have 6 months warranty, I had must consider my data lost and now that hdd is left in service for warranty .

But, when I put the "good" pcb back on the 80gb hdd, it also start clicking . His preamplifier don't have shortcircuit between +5v , -5v and GND pins, his Smooth chip heats up normaly, the platters spins . Is clicking about 15 seconds until the Bios recongnize him as Maxtor Calypso folowed by a firmware number which normaly would be YAR41BW0, but in reality is shown as YAR41KJZ or something like that (I don't remember very well) .

From the description of those two maxtor drive I can say that the pcbs are interchargeable (even de CPUs are the same - Agere Ardent C8-C1 ) .
So where do you think whoul be the problem ? What could I try in order to regain the 80gb hdd functionality ?

Thank you , and please excuse my english skills .

Hello Calypso,
Most probable case is The HD primary head is dead.
But there might have problem also on SA Zone.

Professional Can Identify exactly where the problem is after diagnosing.

I'm afraid that putting the good pcb on the drive with the bad preamplifier killed the good pcb also.
This is a common problem with calypso's.

Best reagerds,

I believe so too, but shahij, why did you think that the problem could be inside the platters room ?

And I don't even think about proffesionals because the data was saved before damaging the drive , and for me, instead asking for proffesional service it's more cheeper to buy a second hard disk drive (the same model) .

So any efforts for recovering this hdd will be done only by myself .

I hope I will find soon enough a compatible pcb for this drive .
I know that must no be any short circuit between +5v,-5v and GND pins of the preamplifier connector . What else must be checked to be sure that a new (eventually) compatible pcb will not be damaged ?
Is there any way to find out if the preamplifier or the heads are damaged ? I mean , checking some voltages, or listening possible strange sounds etc. ?

Calypso,

The preamplifier is in the platters room. If you measure a shortcircuit on the connector to the inner of the drive, this means the preamplifier is dead. Replacing this means replacing the whole headstack, which is a very precise work to be done with the proper tools. If you have never done it, but dont bother about the data, you can give it a try, but i would not like to make a bet on you succeeding


Best regards,

Dobre

dobrevjetser, in my last post I was not talking about the hdd witch have shortcircuit between +5 , -5 and GND pins on the preamplifier (it may be my fault ......I need more practice with English ) .
I was talking about the other hdd (80gb), from witch I taked the pcb for testing the 120gb hard disk drive .
As I already said, the 80gb hdd don't have any shortcircuit between preamplifiers +5,-5 and GND pins so (again) as I said, I doubt that the problem whould be in the platters room .

I don't care anymore about the 120gb hdd since it is left in service for waranty , and even if the data on it is lost or not, anyway it wil be repaired or changed for free .

I looked at the pcb and the +5v and -5v pins of the preamplifier connector are conected with the Smooth chip .
So I think is possible that only the smooth chip be damaged . Am I right ?

Hi Calypso,

Yep, sorry, I misunderstood.
Indeed the chances are high it is only limited to the smooth chip, altough it is much easier to find a replacement board (ebay). You need to match the number on the sticker on the connector of the pcb.

I presume thar you're talking about IDE-ATA connector .
Somewhere in this forum I found that F4FYA, can be changed with L6FYA,M6FYA,F8FYA,K2FYA,N2FYA,L8FYA,M8FYB,G6FYA .
Anyway I found in many places that to swap pcb's it's enough to match de processor model (IN my case AGERE ARDENT C8-C1) .

So, I must find exactly another pcb named F4FYA, or it may work with "replacements" named L6FYA,M6FYA,F8FYA,K2FYA,N2FYA,L8FYA,M8FYB or G6FYA ?

Till now i always had the exact board in stock, never tried with the "replacements".
