Not sure what they're all for, but the 3rd digit is the one too watch out for when doing head swaps.

I opened several old Maxtor drives, all the ones with one type of 3rd digit had the same type of Preamp chip.

open module 83# use pc3000

Ok, thats some good stuff.
But what matches up with what is printed on the lable?

I looked at 2 drives with the code K, G, B, A and nothing in #83 had a "K"

??

First letter "K" is the Preamp type second letter "M" is the head type .

Rameez..

How sure are you about that?

I opened up several 5409U4 drives looking for a donor, and ones with same 1st two digits had completely different preamp chips.

I think we should open such a topic. Outstanding people often stand out. Spildit,pcimage,starling, come on!

Anybody else shed some more light on this?

THis letters wich said´s need for matching MHA to match letters its not always true

I had a Maxtor 2F04L0xxxx patient and search for donnor , bought the hdd donnor, same model, same CODE, SAME LETTERS and when arrive and check lift up the sitcker, the preamplifier was different

that is strange .

yes its true check it




Same Model 2F04L0 Same letters code but preamplifier was different

Do you know anything about Fujitsu laptop drives?

Specifically, I have a few that will not move out of park onto the platters. There is no mechanical impairment and the PCB is not the cause.

Any ideas?

Thanks!

Hi,

As far as I remember I have seen this with 2 different causes:
1. the line that goes to the VCM in the flexible PCB was burnt ->check the resistance from outside.
2. this is not that sure, just a faint memory that a preamp failure caused such thing.

regards,
