7. Q: My RAID system has an actual capacity of more than 2 TB, but in Windows XP and
Windows 2000, it will only do a full format of less than 2 TB in capacity. How can this
be resolved?
A: Since Windows XP 32 bit and Windows 2000 does not support GPT, both can only
continue to use MBR (Master Boot Record), which only supports up to 2TB in one
volume. To see more than 2TB in a single volume in Windows XP or 2000, go to
RAIDGuard X, select "Create Array" and set the sector size to 4096 bytes. By doing
this, Windows XP and 2000 will be able to format an MBR volume greater than 2TB.
However, if the sector size is set to 4096 bytes, it can lower the performance of the
RAID.
8. Q: In Windows Vista and Windows 7, after having confirmed that the files on the
installation CD have been completely installed, why does it still show "Find no RAID
card"?
A: Windows Vista and Windows 7 has a built-in ability to automatically reduce the
potential of security breaches in the system. It does that by automatically enabling
a feature called User Account Control (UAC). When UAC is enabled, the RAIDGuard
X server cannot detect the controller and thus displays the message "Find no RAID
card." To resolve this, disable UAC and run RAIDGuard X server as "administrator".
Vista:
a. Control Panel -> User accounts -> Change security settings -> Deselect "Use
User Account Control (UAC) to help protect your computer."
b. Restart the computer to turn off UAC.
Windows 7:
c. Type "MsConfig" in Start Search to start System Configuration. Then go to
Tools tab, select Change UAC settings, then click on Launch button.
d. Slide the slider bar to the lowest value (towards Never Notify) with the
description showing "Never notify me".
e. Restart the computer to turn off UAC.
9. Q: When inserting the HDD into my B08S2-PS, why does RAIDGuard X show the HDD
mode as Lock?
A: The lock indicates that the HDD has been previous used in Accusys products and
that it contains a portion of a RAID data. If the data can be deleted, you can
unlock the HDD.
10. Q: I have connected the cable to the Host server, but I can't see "new disk drive" on
the host device management.
A: There are three possibilities:
a. Please ensure the QSFP cable is connected securely. You should be able to
hear a "click" sound when you connect the cable to the connector.
b. Please check the jumper switch on the HBA. When the switch is in the "On"
position, the HBA card is enabled for storage mode for the B08S2-PS. In the
"1" position, the HBA is enabled for switch mode for the SW04/08.
