Locked WD1200BEVS need help

[kricker]

I have a friends Dell Inspiron that has suddenly started showing the Dell white screen "drive is locked, enter password" before it boots. She has no idea what the password would be and no idea how to even set one up on it. It just "started happening" I was told. I know for sure she doesn't even know how to get into the BIOS to set it. I've tried using mhdd, but the drive never shows up. I've ran mhdd with /enableprimary (seeing as how the drive should be the primary in the laptop), but the drive still doesn't show up. I'm not sure how to use "zu". Can anyone help me out?

For starters you probably need to change the setting from AHCI to IDE in the BIOS. Probably this is what is preventing you from seeing the drive in MHDD. Alternatively you could just hook the drive up to a separate computer.

[kricker]

I've hooked it up to another laptop with a sata to usb adapter. Maybe I can finally make some progress. I'll post back a bit later.

[drc]

That will still not allow you to access it with MHDD or anything else that does low level operations

[Cleanroom]

Without the password you will need special tools to remove the lock from the hard drive. You will not have any access to the data while it is locked no matter what you hook it up to.

[kricker]

I understand I can not access the files on the drive until it is unlocked. I was hoping to try to use mhdd to find out the password using the various scripts I have seen. The biggest issue I've had is getting the drive to even show up in mhdd. Seeing that it is a sata drive I had a SATA to usb adapter and so far that lets mhdd see it. I'm using the magic boot disk that emulates the usb as scsi. But the unlock command says it only works for IDE.

Now that I can at least see the drive in mhdd, I'll switch to using my desktop PC and see if I can hook it up directly and proceed from there.

[kricker]

Now I may finally be getting somewhere. I have the drive hooked up directly to my desktop pc. In the BIOS I have set SATA as IDE in compatible mode. I am booting off a usb thumbstick, and running MHDD 4.5. The drive is found properly and reports as Security: high, on. I've executed the following script:

Code:

; 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.

I get an error on line 7

Code:

ERROR: No DRQ

... and I do not get the 42.bin file.

[Cleanroom]

I am pretty sure MHDD will not show you the password nor will it unlock for you. The drive will work and ID correctly, just the sectors are locked from reading.

You need to get access to the service area of the drive to unlock the drive and MHDD will most likely not be able to do that for you.

[drc]

That script is intended for drives of an older architecture than the one you have

[r3712]

To unlock drive you got to deal with security module in System Track. Not a lot of data recovery companies can do that.

[drc]

I can think of a lot of things more difficult than getting a password off of a Western Digital. But maybe thats just me.

Also, "security module in system track"? Are you sure you're thinking about the right kind of drive here?

[kricker]

Okay, how about this script:

Code:

;
; MHDD TERMINAL: Sample scripting batch and documentation
; Please also look at "STEST" for SCSI commands
; and "IDESCAN" for an advanced example
reset
waitnbsy

regs = $45 $0b $00 $44 $57 $a0 $80
waitnbsy

regs = $d6 $01 $be $4f $c2 $a0 $b0
waitnbsy
checkdrq
sectorsfrom = cs.bin

regs = $d5 $01 $bf $4f $c2 $a0 $b0
waitnbsy
checkdrq
sectorsto = 21.bin

regs = $d5 $01 $bf $4f $c2 $a0 $b0
waitnbsy
checkdrq
sectorsto = 22.bin

; end

It completes and the 22.bin file I get reads;

The just looks like the ID sector to me, not the security module


Where in the US are you located? You can PM me if you would like me to unlock, it will cost though (not an arm and a leg)

[kricker]

Drive is now UNLOCKED! Master password was in the .bin file. Thanks to posts in other threads I figured out where to look and how to translate it for entering into mhdd. Crisis adverted! The filesystem had some issues and it looks like the drive is going south. Maybe the locking came upon as a symptom of a failing drive (not that I've ever heard of such a thing). Now I'll just backup the data and recommend replacing the drive. Can a forum moderator edit the thread title to reflect it is has been fixed?

[drc]

Good job working it out.

Congratulations! I have )))

[r3712]

I forgot to point to one thing - if HDD will lock itself there is no way to find a password. So based of information given I was talking about this very case.

[kricker]

I think it did lock itself, but using the "Master" password I was able to unlock it. The user password was a bunch of strange characters, but it worked.

When I ran the command. DUMP in MHDD occurred "ERROR: NO DRQ. Please help me how did you solve this error?'m In Brazil and I'm using the Google translation, I can not speak English. Thanks
