How to recover data, damaged external disk (not physically) encrypted Bitlocker ?

    Question

  • Hi,

    please help

    how can I recover data from a damaged disk (not physically) of an external encrypted Bitlocer.

    Description of the situation:

    • After connecting the drive - I can decipher it by typing the password - but when you try to open the contents of the report the message "format disk" - the disk probably has some volume damaged - it has been disconnected from the computer (without being turned off)

    What I have done so far:

    • Using the "Lazesoft" program - I managed to copy (of course after entering the password on the damaged disk) the content to another external disk (full - looking after size) but - this data is encrypted (mainly ending with .ER)

    I am asking for a hint:

    • whether the data that is on the new disk can somehow read (on this disk I can try) [or/and]
    • how to create a damaged disk image to try on another disk [or/and]
    • how to repair a damaged disk (as a last resort) - I am afraid of total data loss [or/and]
    • what other program to use to copy data from a damaged disk
      but decrypted

    Thank you in advance for your help

    Best Regards

    Sławek

  • Hi,

    Can you enter the drive and copy and past files from there to another drive?

    To answer your questions:

    1. Since I don't know much about the  Lazesoft, I don't know why the data is encrypted. As I know, if you copy the files to another drive or a different pc, they will automatically decrypted by default(not using third-party software as a prerequisite). However, your hard drive is corrupted, it is suggested that you disable the bitlocker firstly.

    If you can't not disable bitlocker from Control Panel, you can follow the below steps:

    STEP1: Boot into windows recovery environment.

    STEP2: Open the command line as administrator and type

    manage-bde -status x:

    manage-bde -unlock x: -rp <48 digit recovery password>

    manage-bde -protectors -disable c:

    Then exist and reboot. Use Control Panel to resume Bitlocker protection.

    2.You can choose to back up your damaged disk image and restore it to another disk. reference

    However, since it is corrupted, even if you restore it to another disk, it can't help to fix the problem.

    3.Run chkdsk command as administrator. You can type chkdsk /? to view more option.

  • There is no inherent capability in Windows to recover data from a defective HDD.

    You will have to have you HDD checked by an independent HDD recovery specialist if you need data from your HDD.
