Tips
DISK ACCESS LED momentarily lights green when disk is accessed. If the disk is
accessed while the amber LED is blinking (during synchronizing), the LED seems to
light green and amber alternately.
The time required for synchronization varies depending on the partition size on the
disk.
For a 279 GB partition, it takes about 160 minutes. When the partition does not exist on
the disk, the synchronization is completed immediately after the RDR is set, and
Op
State: State
changes to
Duplex
.
However, when the dynamic disk is used, the time required for synchronization
depends on the disk size regardless of whether or not the partition exists on the disk.
For a 300 GB disk, it takes about 160 minutes.
Important
It is not recommended to reboot the system before the synchronization is
completed. If the system is rebooted before it is completed, the synchronization
process restarts from the beginning and whole area of all partitions need to be
synchronized.
When the system is halted without shutting down Windows properly due to
forced shutdown or others, the entire area of the partition on the synchronized
disks will be resynchronized after the system is restarted.
