It depends on the BIOS. A lot of them freeze the device and so
preventing the security-erase. Have a look at your disk with hdparm
-I. In the last paragraph it will tell you if your disk is frozen.
I use a usb-sata-adapter to issue security-erase commands to drives.
You could also try to hotplug your disk.
