WipeDrive can handle encrypted drives. However there might be a limitation. Locked drives will give issues in most cases.
Software level encryption
Hardware encrypted drives & locked drives
Linux Drive Encryption:
The default encryption used when setting up a Linux OS is no problem at all. The encryption is done on software level.
BitLocker is no problem for WipeDrive.
If a drive is locked due to a hardware lock this will cause issues in most cases.
The lock will be in the BIOS in most cases. This will mean you need a password to unlock the drive.
If you have a drive that looks to be locked, please contact us as firstname.lastname@example.org and send some hardware information in the email. We might give some advice.
