It is important that the correct Blancco erasure software image is used!.Disk detection should be verified at the disk controller's end always, before starting the Blancco erasure software. In the second phase, the internal hard drives should be removed and the external array should be erased separately. First erase the internal drives without the disk array connected. If an erasure has been completed for a server with internal drives and an external disk array, the erasure should be divided into two separate runs.For example: Erase Seagate SAS drives in one batch and Samsung SATA drives in another. If there are larger batches of drives from the same manufacturer, it is recommended that those are also erased separately. For example IDE, SAS/SATA and SCSI drives should be erased in separate batches. Blancco recommends that only the same type of drives are erased simultaneously.After dismantling the RAID build, also make sure that no automatic RAID building options are turned on (this may cause an erasure verification failure). This should be done especially in cases where the physical drives are not detected properly by the Blancco erasure software (only logical RAID volumes are shown or the amount of connected drives is wrong).

It is recommended that the RAID controller's active RAID build is manually dismantled before Blancco erasure software is started.

Old controller firmware might prevent the controller from working with certain type or sized hard drives. Newer firmware version usually fixes possible bugs and increases compatibility with newer hardware.

Make sure that the system's disk controller firmware is updated to the latest version.

If the server or the storage system has multiple power sources or modules, make sure that all of them are connected and operational.

This means that if the drives are removed from the original system and connected to another system, they might not function properly. Some drives might also have a special custom firmware that makes the drives usable only with the original system (disk controller and/or array). If the disk controller's maximum drive limit is reached, Blancco will not be able to detect more drives than the controller is able to present to the system. Be aware of the hardware's technical limitations! Some disk controllers might have technical limitations regarding the maximum amount of connected drives.If the system's disk controller is not able to detect the drives, it will mean that the Blancco erasure software will not be able to do it either. Make sure that the system itself is able to detect the connected drives (see the computer's BIOS or disk/RAID controller's setup utility/BIOS).
