hi to all, I have a hard disk maxtor diamondmax plus 9 pata 80gb with this model: yar41bw0 n, m, g, a serial y20spvvc and code 6y080l0422611 with the engine chip exploded and the chip 22pfs20v exploded. the pcb model is as follows: 301862101 calypso / koi_p7therm. I bought a pcb with the same abbreviation when I feed it the hard disk starts regularly but emits irregular clicks. What can I do ? Thank you all for your help

do you mean the chip on the head? I have also changed the head group, with one of another equal model but has the same defect. I had thought about a mistake in choosing the pcb but I really do not know what to think. Advice?

Yes ... Stop messing with the drive and send it to a real data recovery firm if you need the data.
Some questions :
1 - Did you open the drive and replace the head stack yourself outside a hepa 100 clean room ? Did you at leat use a laminar flow workbench ?
2 - When you did replace the PCB what criteria did you use to chose the new PCB ?
3 - For Head stack what did you match to chose the donor ?
4 - Do you have ANY MAXTOR firmware tool ? Do you even have MRT tool ?
5 - Why did you ask for firmware for your drive on the other thread ?
6 - Are you willing to pay to get the data recovered if possible to recover at all ?

To chose a PCB for your drive you have to match :
1. Full Model Number.
3. Controller version.
To chose a new set of heads (head stack) you do need :
1. Full Model Number.
3. Four characters.
Meaning that the drive that you will use as donnor for heads must be :
n, m, g, a
Match country where the drive was made and try to get a drive as close as possible to yours (date that the drive was made).
Of course that you might have made a big mess right now ....
Are the platters ok ? Did you scratch something ? Did you manage to do a good head swap without leaving dust particles on the platters ?
Also do you have "something" that you can use to load the drive from external loader ?

The drive that i do have for sale will not work as a donnor for your drive but i do have many old maxtor drives from that family that i can check if you need to.
If you do have firmware tools please do let me know.
Also are you willing to pay something like at least 400€ to get the data recovered from your drive ?

Hello, the hard disk is not my property but a client of mine, of course I have mrt and I have everything necessary to change the heads without problems, I do not know why you speak so, do you think you are the only one to have these tools? I asked these questions because I've never worked on such old hdd and frankly thought I could recover data, but this hard drive had a very strong electric shock and many components exploded. The pcb is identical to the old as part number and differs slightly from the original ardent chip, but when it's connected to the power, it's clicks and on mrt is in recovery mode. I'm looking for the firmware notfor this hard drive but for another identical one that has a different problem. Thank you for the information

I did assume that you were a new user as you Joined: 14/9/2018, 17:41
I don't have a cristal ball to tell me that you are on the data recovery field. Majority of people who register here look for D-I-Y- sollutions and are end users not data recovery professionals and people who ask for firmware and have few posts normaly don't have tools to use that same firmware that they seek.
Also make sure that you use a compatible drive for head stack replacement. Can you post both pictures of both drives ? Donor and patient ? It would be "nice" to see the label to check if they are compatible....
Did you inspect platter for damage ? Could you see magnetic substract on the air filter ? Are the new heads ok ? If you move them again to donor drive do they still work ?
