hi to all
i have the above drive that was mounted in an external casing. Drive will power up and spin but not be detected in bios.
Looking at the external drive casing it came from there appears to be a burn mark right where the 2 protection diodes are on the board. the diodes measure ok and i can see no pysical marking to indicate an burns on pcb.

i want to begin by swapping boards to test and see what happens but am not sure if the rom is built in the main chip or not, there is a small 8 pin ic which i think may be the rom but an not sure.

can anyone please clarify if this is the case

picture included.

thank you

Nope, that looks like a transistor / driver array, definitely NOT EEPROM.

I suspect the ROM info is masked in the CPU.

[crecomp]

just swapped boards and the patient board works fine on the donor drive, will look at heads now as there is a clicking sound from drive

thx for reply

[BlackST]

ROM is inside the Marvell CPU. Look at heads...

[crecomp]

finally opened the drive to start testnig it, pc3000 i believe does not have this family in it for support.
there appears to be fine dust particles on the top platter, the filter also looks a bit black from the dust but still looks quite clean.
the top platter looks to be fine, but cant say about the others platters.
when the drive is powered up it spins up normally, all sounds good, heads move ot outer end of platterand then start clicking and moving bakc and forth just around the outer edge of the platter.

so i suspect there may be some scratches around this part of the platter.

any ideas with which i can further try and diagnose this drive, i can replace heads but this may just be a waste if there are scratches there.

thank you

the filter also looks a bit black from the dust but still looks quite clean.

I am sure I don't need to explain why this does not make any sense.

[crecomp]

I see your point , I could say it was a test to see if anyone pays attention to posts when they are written so you pass.
I meant it was a bit discoloured but more clean than dirty

[BlackST]

I skipped this thread...

@crecomp : the ROM is inside the big Marvell BGA chip. If clicking with known good PCB same microcode, 99,999999% you have also head problem / preamp. If recal and spin down, the problem is another.
It is important : you have forever BSY, RDY, nothing at all in MHDD ? AND the terminal log what does it show ?

[N.C.]

the filter also looks a bit black from the dust but still looks quite clean.

If you can see anything in the filter, the drive is already done.
This case needs special techniques to recover only partially..
At this point a really skilled pro can recover about 90-95%.
But if you play more, the chance falls fast to 0.

no no no no... wait... an "impression" can make things appear worse : do a PRECISE analysis of the surface(s) and of the filter before judging the drive.

[crecomp]

thank you for the answers
BlackSt
i checked the log and it is posted as below.
as for indicator lights i am only getting BSY

hi all
i obtained a donor and tried the head swap, i seem to be getting the same noise and log below,

is there any one who can point me in the direction of trying to analyse the above logs in order to try and mabye solve the issue,
ths log was taken from the original drive with original bord and donro heads.

thank you

When I go to turn the computer on, the mainboard powers it up, it makes a clicking sound, like a relay activating every few seconds, it eventually gives up trying to work, and never shows up on windows as a hard drive. What is happening I have all my important data on this disk?
