9YN164-500 (Donor but 2 disc and 4 head in it)

This article is out of date (your drive is not discussed), but it provides useful insight:

The first character in Seagate serial numbers reflects the place of manufacture, while the third character reflects the number of heads.

its too much difficult to find for 7 years HDD. There is another way c'mon.

don't make it so hard
we DR guys doing it -all the time - for much older drives
just bought yesterday a match for a ST manufactured in 2008 - much older then yours
there is a lot of sources out there to buy those stuff

and yes sometimes (rare) its really hard to find a match, but this is part of the job

getting back to your Q

There is another way c'mon.

yes there is
but for that you'll need much more experience

[hyuce]

this is definitely not compatible for donor.

[pcimage]

this is definitely not compatible for donor.

Really?

[data-medics]

It might be compatible, but wouldn't be my first choice of drives to try.

[hyuce]

this is definitely not compatible for donor.

Really?

SN of the patient drive : Z2F

I do not think that the models in the picture are compatible. Donor drive SN start as S2F

I do not think it will be the right choice for me.

am i wrong?

[ubr7]

i dont know i am just newby. Pro can tell me if its compatible or not.

[drHDD]

preamp vendor is different.

[cheadledatarecovery]

I've just worked on one of these. There was decent compatibility between S2F0 and Z2F0 drives. A good recovery was made. It was not necessary to import the head-adaptives into the the ROM.

The physical head map on these disks are 1,2,3,4,5.

For reference, the patient HDD was:

ST2000DM001
SN: S2F0....
9YN164-500
CC4B
SU


Donor was:

ST2000DM001
SN: Z2F0....
9YN164-302
CC4C
TK

I hope this helps.
