Replace a hard drive in a locked computer firmware

One of my users put a firmware password on their Macbook Pro.

This user has died, and the password is now lost.

We really need to get into the hard drive and I was wondering before going through all that trouble, I would be able to exchange this drive to an another Macbook and put it into target disk mode?

  • have you tried that already:
  • Restart your computer, hold down the command and R during startup. This will start you in the recovery system.
  • If you are prompted, select the language from the recovery Partition to use.
  • Click on utility in the menu and then on the menu, click firmware password utility
  • In the dialog box, click the button disable Firmware Password .
  • Enter the password used.
  • Click on disable the Firmward password and restart your computer.

    If you use a perpetual Photoshop and formatted your disc version of starting without disabling your activation of Photoshop, you also Adobe supports help you activate Photoshop once you retrieve your serial number.  The startup disk formatting would destroy that credential of Activation Photoshop machine which is registered in the database of the Adobe activation server. Which reduces the activation numbers you have to use.  If you have Photoshop installed on a second computer that means that you have no free activation available as well, even with your key you can't activated the machine.

    Hello

    I replaced the second hard drive on my HP Pavilion m8120, Vista Home Premium OS due to the imminent failure.  Before that, I called HP Tech Support and I was told that I had to replace the 360 GB HD.  I bought a 1 TB HD that I was told would work in my system.  Following the instructions, I backed up all the files, installed 1 TB HD and down the system recovery.  Now I don't see the disk newly installed in the computer; However, I see it in the disk as ONLINE - not ALLOCATED management.  What must I do to see it in my computer so I can use the new drive?

    Recovery of DNG issue: I have photos stored on an external hard drive which have previously been imported into Lightroom and converted to DNG.  The laptop on which I was running Lightroom died and I had to replace the hard drive and rebuild the computer.  In the process of my Lightroom program and catalog related to these images have been lost.  When I re-associate these photos with my new installation of Lightroom and a new catalogue is there a way to retrieve the keywords or other changes or metadata catalogue Mountaga?  Is any of this information embedded with the imge DNG file or was it only in the cataloght lost on my failing hard drive? I re-import just as if it were new images with no prior treatment of Lightroom?

    By default, LR saves all changes in the catalog, and that applies to any type of file.

    Optionally, you can save changes to the file as well, for raw files owners, this will create a xmp file - for DNG that changes are going to be cooked in the file, without additional xmp file.

    But it does not default. Go to the catalog and parameters under the control of metadata automatically save changes to XMP.

    Unless you do this, the changes are saved only in the catalog.

    Hope this makes things clearer.

  • Recovery disk failure after replacing hard drive of a laptop computer DV7 series

    I have a HP Pavilion dv7-4270us with Windows 7 64 bit and recently received a message on start-up indicating that the intelligent of my hard drive failed. I bought a hybrid Momentus XT drive. I bought the recovery discs, since I neglected to follow my own advice and did not have a game. Replaced the hard drive, and begun the process of recovery, after the disc of the Application, the system was declared finished, clicks the button, the system shuts down. Activated power, recovery took over for a few minutes, declaring that he was copying files, a few minutes later, he said it was over asking me to click done. After that I did it, the system has rebooted hung on the screen of the HP logo with the statement in the lower left corner indicating "press ESC for the Start Menu. My only recourse was to power down the machine. When I restart the computer, I get the message 'Bootmgr' missing

    I have already paid through the forums and tried to download the Windows 7 Home Premium 64 bit DVD of digital life. As it starts installing, it indicates that a driver is missing, I poured by drivers for this computer and see nothing for SATA, and none of the others would be required to start. I succeeded in my Windows 7 Professional on the loading system, but since I don't have an extra code to hang out professional, it's not helping right now.

    I also tried to partition the new disk manually using a device that allows me to see the drive using a USB port and my office, but he's not right. The good news is that the old drive still works to a point. I can read it via USB, and I can back up the drive, with the exception of the recovery partition. But when I put the new disk and set up similar scores for the original drive, it still does not start.

    I have tried many other things all pronounce the failure, I'm not used to failure when it comes to computers, so be gentle.

    Hello:

    The missing pilot is due either to a bad burn or use another brand of DVD. You must burn the ISO at the slowest speed possible file that you can.

    In addition, check the size of the ISO file that you downloaded. Sometimes you do not get the full 3. XX GB even if the download says completed.

    If you have 4 GB or more large USB flash drive, you can install W7 as it.

    Just follow these instructions...

    Download the MS of W7 USB installation tool and read the instructions on the page to use.

    http://www.microsoftstore.com/store/msstore/HTML/p bPage.Help_Win7_usbdvd_dwnTool

    You may also make this mod as I did if the flash tool-error.

    Download the bootsect file form http://www.everettsporting.com/bootsect.zip

    You will need to go into Control Panel, select display large icons, go to the icon of folder options, view tab, and select the hidden files and folders option.

    Once downloaded, copy the BootSect.exe file in the same folder that contains the file of Windows7-USB-DVD-Download - Tool.exe installed. This file in Windows 7's default installation directory is C:\Users\USERNAME\AppData\Local\Apps\Windows 7 USB DVD Download Tool\

    Run the application from the Windows 7 USB/DVD download tool as described on the Microsoft Store website. The end result will give you a boot USB flash drive that contains everything you need to install the 64 bit version of Windows 7.

  • Had to replace my hard drive, computer blocked in 2006

    I recently had to replace the hard drive of my laptop. It's a HP Envy 14 Beats Edition Audio t-1200. I confess that I'm not too knowledgeable about computers, so I don't really know how it works, but here's the gist:

    With the new hard drive, I noticed that several drivers are several years old, and I can't update. For example, the mouse driver is dated 2006, so I can't do the scroll with 2 fingers, and I was able to with the original hard drive. In addition, I have most any bluetooth application, but I know that my phone is bluetooth capable, because I've used it before. Audio also works differently. Whenever I try to update a driver, he says that everything is up to date. Is it possible that I can get my laptop to be as it was when I bought it? Basically, right now, it's like a computer that would have produced 8 years ago.

    I know that these problems are not a huge deal, but I would like to have the computer I originally paid. Help, please!

    Ethan

    All I can think is to make sure that you have turned on Bluetooth switch.

    I see others with other computers of brand having this problem and can't find a solution yet.

    I found this Microsoft, but I don't know if the adapter must be seen first or not for the fix to work.
