FUJITSU MHV2100BH - removing password by TTL

July 20th, 2024, 6:18

Hi

While back I got an old FUJITSU MHV2100BH from an old toshiba laptop, which is locked by high ATA password. ZU seems to support this drive, but it doesn't seem to find it. I have an 5v TTL adaptor, but I/O pads on the PCB are 3.3v. Couldn't find any info about unlocking them by TTL adaptor, preferably with perament data loss since I don't need it. Does anybody know if its possible to remove the password by TTL?

So connect the HDD to the IDE MB. Then the ZU will find it.

Tried on an IDE board which had SATA set as IDE detection. It has kinda worked since it did find it but after 1 sec it said UNLOCK NOT DONE. No idea where to go now. Any ideas?

Soo any ways I can unlock it without paying for pc3k/MRT or for unlocking service?

First of all, I would like to see a picture of the passport in the PIO mode in the Victoria program...
I still don't understand where and how the HDD is connected. :?

Will post the picture later today since my XP rig is acting up... The HDD is connected to the SATA (I think its port 1 or 0) ports on mainboard. The BIOS is detecting SATA ports as IDE ports. I think that is understandable.

It seems like this board (gigabyte) doesn't like password locked HDD's when booting into XP, but has no problem booting into DOS. Tried a different mainboard (this time, an ASUS which detects SATA as SATA). In PIO mode, I get 170h on BASE, 376h on ALT, same as on the gigabyte (without the fujitsu HDD). I'm also getting Port 0170h - drive disconnected!

As far as I remember, the ZU works only with ports 1F0/3F6 (ZU.exe /p) and 170/376 (ZU.exe /s).
For this, you need an old motherboard, on which you need to disable the IDE controller and turn on the SATA controller in IDE mode.
Then the SATA ports will be at the addresses 1F0/3F6 and 170/376.
If you can read the passport of your disk at one of these addresses (the password does not prevent this), then the ZU will work.
Victoria for DOS is also available, as is MHDD. Last version ZU: http://www.hddoracle.com/download/file.php?id=385
If this is difficult for you, buy a beer for a specialist who will help...

Disabled IDE controller and made SATA work as IDE. ZU (version 050911) detected the drive, but the unlock was unsuccessful. It detected the firmware and model, then it power cycled it (POWER OFF/ON) and then unlock not done.... Ill try the latest release and see what happens.

It seems like it unlocked the drive even with that error. Thanks for help
