Hi Guys,

Do you have any idea how can I remove an ATA password from
a HITACHI HTS424040M9AT00. I have PC3K, ISA and PCI versions but either
supports this model for password removal.

I appreciate Any hint or advise.

You need to connect just the PCB in Safe Mode, read NVRAM, make a change to it, and write back. Then re-write a module from another drive/library.

I'm not gonna give full details here, as the procedure can easily go wrong and mess your drive up.

If you wanna chat, msn me

Sean

Hot swap won't work.
This drive also won't let you read any modules when locked unless you make some modifications to NVRAM in safe mode.

Yep, Starling is correct, as usual.

you can also attack password without mod to NVRAM,
and using pci version for this HTS424xxxxM9 model.

How can I attack password by PC3K PCI? It supports
HTS548 and HTS726 series only. I could not find any suitable
place on the PCB to put the jumper pins. Would you please
explain more about your method.

Regards

Last version of PC3000-PCI supports HTS424 family.
Maybe your version not from ACE

I have bought it directly from ACE Russia. I beleive it is the latest version.
Here is the version info:
Product:PC-3000 (PC-3000 PCI(Kernel))
Version: 2.27
Build: 2.2.7.2290

May be you are talking about UDMA version which I don't Have

I have PC3000-PCI from ace Russia and it supports HTS424xxxM9 family.

I don't have the rip off UDMA version because it only adds HTS 541xxxG9 family.

I have UDMA which does support HTS424 family, I also have PCI which does not.

Maybe you mix up HTS421xxxxH9 and HTS424xxxM9 ?

I have version : 2.27.060704 (July 2006)

HTS 424 is supported in 2.27, but not for password unlocking. AFAIK

At least I don't know of probe points, if any exist.

Yes, I have the same problem. Don't know where to put the probes

ace did give points for HTS424, but their probe don't work
because their probe works on about 10-12 ohm.
you need more resistance, but not as much as 20 ohm.

Hi Coffeebean,

Would you please let me know where are that POINTS ?
I have the original PCI manual from Ace. There are no references to HTS424
password removal points in the manual .Perhaps you have the newer version.
If it helps, I can send you the image of the PCB. Then you kindly mark the
points on it.

Hi Pninja,

anyone can figure out these points with a little electronics and HDD knowledge... just need a little time...
The principle of working with these probes is described enough to find out the points for any drive. However Mr. Coffebean has some point, he just have'nt told us wether he's talking about AC or DC resistance and if AC, what frequency....
(I would vote for AC, but not sure)

It's not that I don't want to share knowledge, I never dealt with pwd protected HTS424, so i never had to do it.

regards,
pepe

Hi Pepe,

Thank you for the comment. I always find something new reading your posts.
Indeed, I have that "a little electronics and HDD knowledge",
but problem is, I am deadly in lack of time for this special case.
That is why I asked our knowledgeable friends here for help.
I thought if I rush for a try and error solution without enough
research I may destroy the PCB.
Thanks to Starling, Pcimage, Coffeebean and many others for their help.
I think I received enough advise to solve the problem

Here's a picture I got from Acelab for HTS424.
But it didn't work in my case, so I went with NVRAM method.

Hi Starling,

Nice pic you got from ace.
You know where they got it from ?

You know now why ace so reluctant to publish help and
provide assistance, cause you take some valuable information
you got from ace and you publish it here.

Now you know ace won't get much help (cause they did not discover
IBM solution) so you shoot three shots into each of your own feet
for the future - your own future and many others.

I think you just little boy trying to find beanies for your ego....

Hi Starling,

Thank you for the PCB image.
As you have mentioned NV-RAM method works great.
I could unlock the drive easily following the instructions which
I received from you and PCimage
