DESlock+ client v4.6.4 or older provides limited compatibility with RAID controllers when using Full Disk Encryption.
This has been improved in clients v4.7.x onwards.
If you are starting encryption on a client directly and seeing the warning dialog below then you should upgrade your client to the latest version before attempting encryption.
The same error can be reported by the Enterprise Server when attempting Full Disk Encryption. In this case you will need to update your Enterprise Server to v2.5.x or later and use client v4.7.x or later.
If you are still unsure please contact DESlock+ Technical Support for assistance.
