Fijitsu MJA2250BH firmware issue

[sosrecup]

Hello,

I have an apple 2.5" drive :

Fijitsu MJA2250BH
Date: 24-08-2009
Capacity: 320G
Country: Thailand

When I connect it to PC3000, it is recognized and reaches readiness but when I choose Fijitsu 2.5 family utility, the drive is not present in the list and when I choose other SATA drive, the ID is not read.

the drive doesn't produce any strange sound. it spin well.

Is this drive recognized by PC3000? if no, is there a solution for such a case?

Kind regards,

Hi, that drive could not be 320GB. it's a 250Gb
Do you use Pc3000 pci or Udma?
Fujitsu drives has not often firmware issues.

It's heads issue. High chance of media damage.

I'm using PC3000 UDMA.

the drive spin well and there is no strange sound. it reaches readiness. could this be a Head problem?

[labtech]

Have you opened the drive in a cleanroom environment already? If so, did you notice anything suspicious?

[sosrecup]

Sorry but the model is MJA2320BH and not MJA2250BH. I did a mistake when typing.

this model is recognized by PC3000 but unfortunately, it can't read the drive ID. the drive spin fine.

Do the heads attempt to read SA? Do you hear any activity?

[sosrecup]

No I don't hear any activity and any strange sound.

Do you hear the heads sweep out from the ramp?

If not, it could be either PCB or preamp. Have seen both of these cause this on this series.

it could be either PCB or preamp.

Measure the voltages at the HDA connector with the PCB on and off the drive. This should help to determine whether the preamp is at least partially functional. For example, the write channel pins will probably sit at 0V when the PCB is off the drive, and at around 1V or more when the PCB is on the HDA.

[sosrecup]

fzabkar, could you please show where can I find the write channel?

[fzabkar]

I think the differential pair with the visible terminators is the read channel. The pair on the left would then be the write channel.

BTW, you need to measure the voltages between each pin and ground, not between each pin in the pair.
