Safe Removal Of The Raid System - Sabio DM4 User Manual

The Connection LED is only one-color (white). When the HDD is connected, the
white LED will be on. The Connection LED also indicates HDD power status and
disk rebuild status. When the target HDD is being rebuilt, the white LED will
blink.
The Health/Access LED is dual-color (red/blue). The red color is for Health
condition. The blue color is for Access condition. When the HDD is not healthy,
the red LED will be on. When the HDD is being accessed, the blue LED will
flash. When HDD is healthy and not being accessed, no LED color will be on.

The difference between a flashing LED and a blinking LED is that flashing
refers to the read/write activity and blinking refers to slow but regular pulses.

SAFE REMOVAL OF THE RAID SYSTEM

Safe removal of the Enclosure from the host controller is highly recommended,
especially when switching interfaces. In order to safely remove your Enclosure
from the host controller, you would need to eject the device on your host
controller system.
If using a Mac System, safe removal of the Enclosure from the host for all
interfaces is necessary.
If using a PC System, safe removal of the RAID System from the host
depends on the interface. Most current USB and FireWire host controllers
handle USB and FireWire devices as external devices; thus, it is highly
recommended that the Enclosure be safely removed from the host if you are
using either one of the interfaces. However, if you are using the eSATA
interface, depending on the eSATA controller, the host may handle external
eSATA HDD devices as internal HDD devices. If so, safe removal of the
Enclosure from the host is unnecessary.
