    Thx LatinMcG


    My hdd is a new ssd, and it is an OCZ Vertex. So I have to get another way to recover the lock. Or maybe I can reset it back to factory default state... i hope it will clear the psw too

    I can't get the HDD's with 14 character serials to unlock.

    svctag 625PM21-595B
    HDD Serial# CLP429F4GPS18A

    I assume you put ***429F4GPS18A-595B into the program but it isn't working.
    When the HDD Serial is 14 characters you replace the first 3 characters from the left with stars and use the remaining 11 characters is how I understand it but I keep getting the error:
    - Invalid service tag in input string, allowed only -D35B and other registered

    I get the same with this hdd serial also:

    svctag CP3K1K1 from a Inspiron 1545
    hdd serial
    S1YMJ90SB20032

    any help would be greatly appreciated

    I could really use some help unlocking the HDD Password on my Dell Mini10v. Received it back from a diss hearted technician who decided to lock it down before he quit. I had to replace the Mainboard to get by the BIOS password. I tried using a dell key gen, but the passwords did not work. Now that I have the mainboard replaced I am being prompted for the HDD password. I have two service tags numbers. The original that came with the laptop, and the one for the mainboard I just installed. Original is:8HQ32L1 New Tag:7LW44L1

    Anyone help me with this one?

    First, you'll need to downgrade your BIOS to A15 to revert to the old master password scheme. Use the HDR recovery method link in my signature.

    Then once you do that, you should get prompted for a password for this: BNCFX3J-595B
    Use the password below for it.

    Code:
    My own utility. Copyright (C) 2007-2010 hpgl, Russia
    Short service tag should be right padded with '*' up to length 7 chars
    HDD serial number is right 11 chars from real HDDSerNum left padded with '*'
    Some BIOSes has left pad HDD serial number with spaces instead '*'
    Input: #BNCFX3J-595B
    15.09.2012 23:57 DELL service tag: BNCFX3J-595B password: zzje410i

    If the HDD password is incorrect (most of the time it's not right), then you'll need to install your SATA hard drive into a desktop computer and use MHDD to read the flash chip on the hard drive for the user or master password in plain text.

    You might not even need to go that route if you specify your hard drive make & model. Google for the default manufacturer master password.

    You can even use something like a Linux LiveCD with hdparm to unlock the drive.

    I have Ubunto LiveCD and just download hdparm (Now I need to google how to use it)... I give it a try once I get back home tonight... I haven't give it a try before because I was doubtful if Ubunto LiveCD will be able to detect the hard drive since it is asking for password before I even get able to boot from the CD.

    Anyway I'll give it a shot tonight. I pray it works.

    Which command should I use for hdparm?
    hdparm --security-erase-enhanced NULL /dev/sdX
    or
    1. Make sure you are logged into the system as root. You can use a boot disk.
    2 Issue the hdparm command as root and check the drive is not security frozen
    a. hdparm -I /dev/sda
    b. The result should contain the words "not frozen"
    3 Issue the command to
    a. hdparm --user-master u --security-set-pass Eins /dev/sda
    4 Confirm the process
    a. hdparm -I /dev/sda
    b. look for the word "enabled" in the output
    5 Issue the AT SE command
    a. hdparm --user-master u --security-erase Eins /dev/sda
    6 When the drive is erased, the output verification will return "not enabled", check using the command:
    a. hdparm -I /dev/sda

    If the hard drive is locked, then you must put the drive into a desktop PC. The Dell laptop BIOS will block any hard drive access and make it appear as there is no drive there.

    Use any method you can (MHDD or Linux LiveCD). Either should be fine if you know what the default master/manufacturer password is on the hard drive. If you need any further help, I suggest you post your hard drive make & model.

    I tried using Ubunto LiveCD but no luck detecting the HD. I think I may need to make it external. I removed the Hard Disk and brought to three nearby computer shop but they don't have an enclosure or cable to make it an external Hard Disk.
    Now, I'm thinking I might need to either buy a new HD or somehow crack the HD password.
    My Hard Disk is:
    Samsung
    Model: HS08XJC
    HDD P/N: HS08XJC/D
    lba 153,301,488 80gb n1c
    S/N: S18EJ16PB06838

    Any help extended is highly appreciated. I'm open for any suggestion
