  1. Insert the USB memory into the computer

Hard disk related

  • Parted Magic
    Operations such as partition operations and data recovery/deletion are possible.

    Since it uses a lot of memory, please use 512MB with plenty of room.
  • HDAT2
    Hard disk diagnostic tool.
    You can also diagnose and repair bad sectors.
    There are many other things you can do, but if you want to diagnose your hard disk, select the "Device tests menu".
    If the audio is too loud, you can toggle the settings by pressing the "Ctrl" and "S" keys.
  • Drive Fitness Test
    This is a tool that allows you to check if there are any errors on your hard disk.
    There is a quick test, which is a simple diagnosis that takes just a few minutes, and an advanced test, which is a detailed diagnosis. You should expect the advanced test to take about 30 minutes.
    Drive Fitness Test can place a large burden on your hard disk, so we recommend that you back up your data just in case when using this software.

disk copy

  • ddrescue
    A tool for data copying.
    Start Parted Magic and select the computer icon displayed on the taskbar to start ddrescue.

Partition related

  • Test disk
    A tool for recovering partitions.

file recovery

  • Photorec
    This is file recovery software.
    However, file names are not restored.
    The "File Opt" option allows you to select and switch the extensions of the data to be restored, so it is better to prioritize and set the extensions to be restored. Setting this setting will also change the time it takes to restore.

    You can completely erase data on your hard disk.

    Therefore, we recommend that you make a backup.

BIOS password release

  • CmosPwd
    This is a tool to remove the BIOS password.
    The BIOS password can be cleared by clearing the CMOS, but in the case of laptops, the BIOS password may not be stored in the CMOS but in the EEPROM. In that case, you cannot remove the BIOS password even if you use this tool.
    It is also possible to dump CMOS information.
    In some cases, you may even be able to find the password string.
    CmosPwd is a tool that may cause your PC to not start in the worst case scenario, so please be careful when using it.

    "boot.ini" is a Windows system file, and if there is a problem with it, Windows may not be able to start.

    If you start "EditBINI" and select the partition containing "boot.ini", you can edit it like a text editor. (If the selected partition does not have "boot.ini", EditBINI will exit)
    Once you have finished editing the content, press the F10 key to exit.
