I can access the drive using dislocker but I want to remove the encryption. I have migrated from Windows 10 to ubuntu 14.04 so I can't remove it using Windows.

  • Do you want to just overwrite everything, no file recovery or decryption? – Xen2050 Apr 28 '16 at 12:58
  • @Xen2050 - I want to remove the encryption. The files should not be removed. – Gibreel Abdullah Apr 28 '16 at 16:36

    Ok, so trying to decrypt BitLocker using only Ubuntu... this question has been asked before, and there doesn't appear to be a clear answer. See http://askubuntu.com/a/199222/129271 that suggests trying [Dislocker](http://www.hsc.fr/ressources/outils/dislocker/) Or this Q is a better match: http://askubuntu.com/questions/617950/use-windows-bitlocker-encrypted-drive-on-ubuntu-14-04-lts?rq=1 – Xen2050 Apr 28 '16 at 23:35

  • Found a **Better duplicate Q: http://askubuntu.com/questions/617950/use-windows-bitlocker-encrypted-drive-on-ubuntu-14-04-lts?rq=1 .** , but it says I can't vote again if I retract this vote... – Xen2050 Apr 28 '16 at 23:39
  • @Xen2050 - I should have clearly specified this before. I want to remove the decryption. I can already access the drives using dislocker. I want to decrypt my drive so that i don't have to use dislocker tool every time I need to access my drive. Kind of like turning off bitlocker permanently. – Gibreel Abdullah Apr 29 '16 at 05:59

I want to remove the decryption... I want to decrypt my drive so that i don't have to use dislocker tool every time I need to access my drive. Kind of like turning off bitlocker permanently.

That's similar to re-formatting any drive with a new filesystem, but to keep the files there are a few more steps:

  1. Copy the files somewhere else (in this case using Dislocker). This is an excellent opportunity to make a backup copy too.
  2. Format the partition with a filesystem of your choice (ex. using mkfs.ext3, etc). If you still wanted encryption, LUKS works well for linux partitions, or there are other options too for folder/files, ArchWiki has a good overview.
  3. Copy the files back onto the partition.

I don't think any in-place Bitlocker encryption removal tool exists that could do it all at once, and it would have a high risk of data loss should something go wrong anyway.

  • So basically, no way to do it. Thanx anyway. Is there any cross platform encryptor? – Gibreel Abdullah Apr 29 '16 at 15:29
  • TrueCrypt used to be THE one. The [ArchWiki Encryption Comparison table](https://wiki.archlinux.org/index.php/Disk_encryption#Comparison_table) has a compatibility with Win/Mac/FreeBSD section, it looks like programs TrueCrypt, FreeOTFE & CrossCrypt are abandoned, but there are several TrueCrypt successors (LUKS's cryptsetup supports truecrypt) and DOXBOX is now called " LibreCrypt: Transparent on-the-fly disk encryption for Windows. LUKS compatible" – Xen2050 Apr 30 '16 at 03:36
