Bypass ATA Password

Recommended Posts

Hey everybody,

 

A friend of mine asked me to look @ his kidz laptops. He told me that windows would let them logon.

 

Yeah, well when I booted them they halt. Asking for a password. Says that the HDDs are password protected.

 

I asked my friend & he said that the kids didn't set this. I told him that if they didn't then the drive would be failing. But for it to happening on both laptops is odd & less likly the drives on both fail at the same time. So I told thim they must have set it. The kids swear that they didnt. So here I am just about ready to format the drives & do a fresh install. But I dont want to do all of that work I would rather obtain the passwords.

 

I now that it can be circumvented just don't know how.

 

Any help on this would be appreciated.

 

dirty, ;p

Yup I tried that last week. [Hirens15.2] Maybe I just didn't find the right solution yet.

There are a lot of threads on the net about that, the most hilarious is one on a Texas campus site

Then, a bit more serious

Last I will help you and for free to get rid of that password !!!!


First just to grab a copy of MHDD prior to the latest version.
Download MHDD 4.5 from here :
http://hddguru.com/content/en/software/2005.10.02-MHDD/
You will need it because it contain the ATA terminal that you will need for our little experience. Also use the floppy version, if you use the CD ISO you will end up with a "virtual ram drive" when you boot the MHDD and not the real a: assigned to the floppy.

Then open your notepad and past the following script :
; rm modul id 42
reset
waitnbsy
regs = $57 $44 $43 $00 $00 $a0 $8a
waitnbsy
regs = $00 $02 $00 $00 $0F $E0 $21
waitnbsy
checkdrq
sectorsto = 42.bin
; End. 

save the file with a simple name, like "wdpwd" and remove the .txt extension to the file. You should end up with a filename without extension. Save that file to the "Scripts" folder of your MHDD 4.5

Now boot your MHDD copy and detect the locked drive. Mhdd will tell you the drive is locked. Don't worry and issue a .wdpwd or whatever you named the file.

You should end up with a file named 42.bin on the disk you used to boot MHDD.
If you have booted from cd you will have to copy the file out of it to a floppy, etc ...
Post the content here, if you can't figure out where the password is icon_wink.gif

Happy unlocking for free !
Without expensive tools.
That experience will also give you an idea about the true importance of vendor-specific ata commands, and in any case will teach you a bit about HDD

 

Have fun! Cheers :D
