Q. Does XErase properly erase hybrid drives?
A. Yes. But this does of course depend on the firmware of the drive. Navigate to Customize->Interface->Erasure Settings and select Treat Hybrid Drives as SSD. Select on and hit the update button. From now on, detected Hybrid drives will use the SSD erasure settings for firmware based erasure. This erases both the spinning media and the flash media as opposed to overwrites that will erase the spinning media but not the flash.
