Yes, all Blancco Drive Eraser (Server) releases, starting from version 5.10, have hot-swap support, but this has to be enabled by using Blancco Drive Eraser Configuration Tool:

1. Load the BDE image in BDECT.
2. Enable the “report per drive” setting (Security tab).
3. Enable the “hotplug” setting (OS tab).
4. Save the BDE image. After booting it, you will see a “Refresh drive list” button in the BDE UI (Erasure-step). Whenever you plug (unplug) a drive, press the “Refresh drive list” button in order to access (remove) the drive from the UI.

The hotplug mode works with the “report per drive” mode, meaning that one report will be created per erased drive (and not one single report per machine). The hotplug works with HBAs and some RAID controllers* as of version 6.12.0 onwards if using 6.11.0 or earlier the RAID controller needs to have the option to be set to JBOD mode to be compatible.

Read more about hot-swapping from the Blancco Drive Eraser user manual ("Hot-swap capability" chapter).
