[pikus_09]

Hi, i have Toshiba Hard Drive MQ01ABD100 1TB, Disk have changed Master password, and add user password.
Disk is not DVR blocked.
How can I restore master password, and remove user password?
Trying ZU program, and i wait ok 30 min and zero change, and program not work, how can enter safe mode?
Data is not important, and i Use Sediv latest ver 5333.

No i dont know user password, and Master password.
I can't read everything, Terminal is not access, and i cant read ROM.

Try it,
I dont think that this disk Is self encrypted like DVR locked, only have 2 passwords, one is Master and two is User password.

Rom is W25Q80(1MB file), not is W25X40
Now reading Rom via external programmer

I have ABD series but trhis is 500Gig, and FW AX001U, and this disk have other PCB, but have the same CPU.

[pikus_09]

well, i find strange enties in my rom copy, first entrie PQ at offsets 0x F0000-F0094 and E0000-E0099. So maybe prepare ROM to 512KB and write to disk? Hmm?

Ok, But Cps are propably invalid, because program not support 1Mb Roms only 512Kb, and maybe adress are invalid, and Cp are invalid?
So i must prepare rom to 512KB, to be able to extract rom modules. and compare with other rom from ABD, and only different is in Cps.

[pikus_09]

This anywhere not cant fing ABD100 with Rom code 1MB file only 512Kb, and main rom code is everywhere the same.

You probably didn't choose the right channel.

or your drive is defective.
(for example, works BGMs)


Here's an example of how to work with ABD

Code:

4DOS EMS swapping initialized (240K)
4DOS running under Windows 98

4DOS 7,50   (Win98) DOS 7,10
Copyright 1988-2004  Rex Conn & JP Software Inc.  All Rights Reserved


c:\_dumps\#zu.betta_fix_020813>zu /a

AX001C  TOSHIBA MQ01ABD075    <------------------
POWER OFF/ON
UNLOCK DONE
c:\_dumps\#zu.betta_fix_020813>


[pikus_09]

Program work, I run my Pc on Ms DOS, and program detect Disk, but Program say UNLOCK NOT DONE, and exit.
and my Disk is Newest ABD series 2016year, and FW id not AX001C only AX1P5E.

And the hdd is not read only ?

30 minutes to work to only pull one line, that's not much?

@Moltke,

Is it possible to download that new version of zu ?

Thanks

No, Hdd is not read only, and still victoria say that HDD is locked by ata password.

@Moltke,

Is it possible to download that new version of zu ?

Thanks

There was no new version.
I dropped the project

[Moltke]

No, Hdd is not read only

How did you check?

[pikus_09]

Because, i cant read everything, Cps tracks, and ROM, terminal not access,
And Active Flag I have PWD.

[Moltke]

When the disk is in the read-only state, it cannot write.
And therefore cannot reset the password.
