Guralp Systems CMG-DCM build <10,000 - Manual (Page 108)

CMG-EAM (Platinum Firmware)
To prepare the disk on the CMG-EAM using the web interface, select
the “Removable disk” item from the “Tools” menu and then click on
the “Format disk” button. After a delay, while the disk powers up, the
following screen will appear:
The drop-down menus for device selection use the Linux device
naming convention, where /dev/sda is the first device, /dev/sdb is
the second and so on. Individual partitions on devices are identified
by an appended number, so /dev/sda1 is the first partition on the
first device and /dev/sdb3 is the third partition on the second device.
The “Partition” button causes the selected device to be repartitioned
with a single partition which is then reformatted. If you are using a
device with existing partitions that you wish to preserve, you should
use the “Format” button instead.
Successful completion of the format is signalled by a short, on-screen
message. The disk is then ready for use.
Disks can also be formatted from the command line with the command
eam999 ~ # rdisk format
