Hi guys,
first thanks for this great forum! :good:

Maybe someone has experienced similar symptoms and has any idea for that:
My dead MQ01ABD100H (Hybrid) at serial TTL interface reports
SIGNATURE SCAN FAILED
P90 FATAL
HDD FATAL ERROR

Does anyone know what "P90" means?

I think there is a failure in the controller - maybe firmware or internal MCU ROM corrupted. That's because there were no symptoms of upcoming failures like read errors or so. No suspicious noise - drive is spinning, heads are moving - just suddenly no access to any cylinder. :( :(

Btw - does someone have a description of toshiba terminal commands? I find everything for seagate, but nothing toshiba related.

Thanks to everyone who might can help!

Cheers!
Karsten

Hi again,
meanwhile I found some usefull information for terminaling into the 88i9317-RAI2 - might be helpful for some of you guys:
    BSxxxx - set segment for memory access
    CR - ROM checksum MPU
    DB - output Buffer RAM dump at the current segment.
    DM - Output microprocessor unit (MPU) RAM dump at current segment.
    DRx - display peripheral register (H,B,C,D,M,S)
    HP - Output short list of terminal commands.
    LP - Start the flash programming mode. Mode entry will require a key
    LM - translate drive programming mode ROM, wait sync symbols and retrieve ROM data in batch mode
    RS - Factory reset, exit from the terminal.
    SC - Output information about coordinates of the reading/writing heads.
    SD - Output information about physical HDD parameters.
    SF - output information about the status of HDD features.
    SI - Increase by 1 the index of the output buffer.
    SL - Output information about HDD Security parameters.
    SMhh - switch overhead storage mode
    SO - Output extended information about HDD SMART parameters.
    SP - Switch ARRE mode. (Enable/disable)
    SR - output information about HDD SMART parameters
    STxxxx - Set a memory block address for read/write, xxxx - address.
    SW - Output information about HDD power parameters.
    VKhh - set output block size at terminal (00-FF)
    VR - Output microprogram version.
    VM - Output microprogram version
    VVxx - set segment for DB read
    WBxxxx - Write xxxx word to the address in buffer RAM defined by the ST and BS commands
    WMxxxx - Write xxxx word to the address in MPU RAM defined by the ST and BS commands
    WRxxxx - write pripheral registers
    TM - show current time
    TR - show HIC & Temp
    WSxxyy - write to RIC (xx=adress, yy=data)

My goal is to copy internal ROM of the MCU to a healthy board of same type because I need adaptive data to be transferred. BUT big prob is: I am a real novice in this kind of stuff :? ! So maybe someone might help me out of pity :beer: ...

As far as I know, ROM can be read at FFFF0000. But what is the size and how to flash it to the new board? Seems very complicated. I can write a program to read and save everything via BS, ST and DM but have no idea how to deal with LP,LM or whatevere I need to rewrite it to the new board.

I will go on researching but I'm sure some of you know what to do...

Thanks for any advise!
Karsten

Hi drdoc. You did not say if/how you fixed it.

What were the steps if recovered?

Thanks,
-DP
