STM3320614AS remains busy after partiial recovery

[hddr49]

Hi there

I work on a Seagate/Maxtor STM3320614AS
PC3K recognise it at STM3320613AS

At the beginning, I save Hdd resources (indicates error on heads 4-5-6-7 but drive had only 0-1-2-3 heads)
I access the data in DE, begin to save it (with many abr, low speed access)

suddenly after 86 GB saved, disk turn off

since, disk remains busy.
I try the method to unlock in terminal, but I had nothing in terminal :
pcb only, terminal connector, in terminal, CTRL+Z = nothing happens, don't see F3>

May I swap pcb ? no need for chip unsoldering, because I have hdd resources...

What should I look for PCB compatibility ? P/N ? Firmware ? Site code ? other ?

thanks.

Check terminal output and post here before you try anything else. It is important to get the diagnosis right to prevent further problems

like i said, there is nothing in the terminal output.

During data recover, I have something like

"file.... recovered"
"switch off power"
"switch on power"
"timeout 2500 ms"

and nothing more.

This is not F3, you need use old utility with baud rate at 9600

Thanks for help.

Are you sure this is not F3?
On labels I see
DiamondMax 22
3.5 series 7200.11

F3 series begin with 7200.11 in PC3K...

I try old utility, but I don't see this model. I try with approching one, but terminal output is always empty.

[AJ2008]

You are right, it is F3.

You need to check terminal tab on power on, in previous post you wrote log, I need to see terminal

[hddr49]

Unfortunatly, there is no terminal output.

Really, nothing.

I plug another disk (Seagate 7200.12) to see if it works well, and it does
terminal output for the other disk :

Code: Select all

Rst 0x08M
Servo Processor Is Reset
RW: Disc Ctlr Initialization Completed

ExecuteSpinRequest

(P) SATA Reset

I come back to this case, with new facts.

So, I try to swap PCB (100504364 REV B).
I take same PCB (I found one from STM3320614AS and one from ST332063AS)

Unsoldering with temperature-controlled desodlering / Reworking station
I use Hot Air Gun at 300°C


I put the rom on the STM PCB.
When I plug the disk and power on, I have DWF & CRR on red.
And, nothing on terminal either.
Only with PCB, no disk, I have DRD + DSC green, no terminal output.

What do you think of this ?
- Is rom out of order ?
- May I try the rom on the ST PCB ?
- Is my soldering bad ?

I for sure continue to try by myself, but if you have any idea, it would be great.

Thanks !

Precisions :

with donnor from ST, PCB only, DRD + DSC ok, Model ST_M13FQBL Serial QNR_BFW Firmware 1117F38D Capa 3.86 GB, no terminal output

With PCB on disk, DRD + DSC, copying data right now.
