DISCREPANCY IN DRIVE CAPACITY
Q:
I have a 1TB drive, why does the XD5 report the drive available space as less
than 1TB?
A:
Your computer reports the capacity of a hard drive in binary, compared to the
decimal system used to identify the capacity of hard drives.
Binary
, a kilobyte is equal to 1024 bytes
Decimal
, a kilobyte is equal to 1000 bytes
Therefore, the binary system of the computer divides the decimal capacity of the
drive by 1024 instead of 1000, thereby the reported size is reduced. An in-depth
description of capacity discrepancy can be found at

.
REBUILD
Q:
Does the XD5 have to be connected to the host computer when it is in rebuild
mode?
A:
No, it does not have to be. The XD5 can support offline rebuild in RAID 1, 10,
3, 5 which means it can perform the rebuild function without being connected to
a host computer.
CAPACITY OVER 2TB
Q:
What is the “Over 2TB” option for in the PC’s version of RAID Master?
A:
The maximum storage capacity is affected by the Windows operating system.
NTSF formatted drives on Windows XP are only supported up to 2TB. NTSF
formatted drives on Windows Vista and 7 are supported up to 16384 TB. If the
combined drive capacity is over 2TB and the operating system can support drives
of more than 2TB, check
the “Over 2TB” option under the “Configuration” option
tab.
The XD5 requires OS 10.4 and above for MAC, which supports over 2TB drives.
the “Over 2TB” option does not appear on the RAID Master for MAC.
