Replacing Burned-out Electronics in Seagate 40GB ST340016A: Compatibility with Other Models?

Hello.
I will start with what happened to the disc: namely, a slightly higher voltage than it should have gone, and the electronics probably burned out because something else.
I am only looking everywhere: on auction (Allegro), commission etc.
And I can not find the same hiss with good electronics. does it have to be the same models the same capacity and the same company?
Because on Allegro I can get rid of disks with good electronics that would come to me, Drive: Seagate 40GB 7200r. model: ST340016A, there are other models and differ eg in ST340014A or other capacity, which electronics would come from me (from which disk).

Greetings.
I am asking for advice

You must look for electronics exactly to the model of the disk you have, or
ST340016A. It would also be good if the version of the electronics board would be compatible with yours.

Version - IMPORTANT!
I tried to swap places in ST340016A versions 3.05 and 3.75 and none of this
In contrast, 3.05 and 3.10 in the order of

Hello in these models must only agree the firmver capacity can
to be even bigger, if you have efficient electronics and other firmver it is enough to sell a flash from the broken unless it also fell.
I am looking for a flash since 3.05 I can change it to another.W-wa 608 795 989

Hello,

I had a similar problem. I was the owner of the Seagate U4 8GB drive, with inefficient electronics (the disk hung the computer). My colleague had a 6GB Seagate U4, with the disc having some physical bugs, and he could not do anything about it, so the disc gave me. After swapping the electronics, the disk is flashing, it is detected as 8GB (this is the capacity of the disks).
Thus, as satgal wrote, disk capacity is not critical.
Disks also differ in firmware: initially 8-gig had versions 8.01, while 6-gig versions - 6.01. Now the 8-gig disc works with 6-gig electronics, which means it has older firmware, but it is still detected correctly. In addition, both disks differ in CHS factors. Despite all these differences, the folder is detected correctly, and works very steadily.
I drew the conclusion that firmware compatibility is not necessary, but it is necessary to have a firmware version that will automatically configure the disk as soon as the computer is started, based on the information read from the hard disk itself (flash systems).

And I have a few pins from the cable connection ideally broken. Is it possible to exchange all the electronics or give advice only to solder the connector itself (all this rear rail with connection to voltage, cable and jumpers)

Hello.

piotrek power - you can see - here it is: http://www.hadek.pl/dyski.html

If not the 8O prices yet

Greetings.

Ps.
Of course, they do not sell electronics here, but in an out of the ordinary situation (it's about making a diagnosis - disk or electronics), the offer can be a good alternative.

you can easily crush. I did it many times with different disks and there were no problems. You only have to get the same pins.

as for moving the electronics itself, the seagate is different: in older discs up to 20gb (medalist), of course, it can be from a disc with different capacity and does not necessarily have to be the same firmware, one of these newer disks (baracuda) are more demanding and it is necessary to find electronics with the same firmware, and even the same p / n
I've fought the 120gb for the last time, it's the same and it did not start, it was only the third electronics that was all right.
whereas when it comes to soldering pins, it's only for the steel nerves and very precise hands, and of course the equipment because the rest of the pins fall out 8O
