CMG-DCM
5.3 Disk tools
The buttons on this page allow you to perform some important actions on the
DCM's primary hard disk. By default, the module looks for a connected USB
hard disk to use as its primary storage medium. If no suitable storage medium
can be found, you will see the message Failed to find a USB disk
when you attempt to perform any of these actions.
Partition, and format disk
Before using the CMG-DCM you should ensure that its primary hard disk is
ready to receive data by partitioning and formatting it. The DCM uses a special
journalling format for the hard disk which is designed to maintain the integrity
of your data at all times. The hard disk is guaranteed to contain a FAT32-
compatible filesystem, even if a write operation fails or is aborted suddenly.
Check disk filesystem
Clicking on this button will verify the integrity of the hard disk's filesystem. It is
recommended that you do this immediately after installing the device.
Flush flash
Clicking on this button will cause the DCM to dump the current contents of its
Flash memory to the hard disk, thus synchronizing it with the most current data.
If you want to remove or replace the DCM's hard disk, using this tool will
ensure that the outgoing disk is up-to-date. Flush flash does not remove data
from the DCM's on-board Flash memory. If you Flush flash and then swap hard
disks, the data remaining in memory will later be written out to the new hard
disk, causing some overlap between it and the old disk.
