DISCREPANCY IN REPORTED & ACTUAL SIZE
CAPACITY
Q: If I have a 750GB HDD, why does the RAID Unit only recognized the HDD
available space as to be less than 750GB?
A: Many customers are confused by their host systems when it reports a
discrepancy between reported capacity and actual capacity. Several factors can
come into play when your host system views and reports the capacity of a hard
drive. There are actually two different numbering systems used to express units
of storage capacity:
Binary, which says that a kilobyte is equal to 1024 bytes; and
Decimal, which says that a kilobyte is equal to 1000 bytes.
Most commonly used to display storage capacity is in Decimal. The surprising
fact is that even though it seems like you will have more bytes under Binary, the
Decimal calculation system actually presents a greater storage capacity. More
description on capacity issues can be found at the Seagate website under FAQs.

REBUILD
Q: Does the RAID Unit have to be connected to the host computer when it is in
rebuild mode?
A: No, it does not have to be. The RAID Unit can support offline rebuild, which
means it can perform the rebuild function without being connected to a host
computer.
RAID MASTER: CONNECTION RESTRICTION
Q: Is there any connection restrictions for the RAID MASTER?
A: Yes, the RAID MASTER can only be operated via USB 2.0 or FireWire 800. If
you choose to use eSATA for data transferring, please set up the RAID
configuration via USB or FireWire first.
