5.3 View Connected Drives:
A RAID system consists of many physical drives that can be modified and configured as the
members of one or several logical drives.
Press the front panel ENT button for two seconds to enter the Main Menu. Use the up or down
arrow keys to navigate through the menus. Choose "View and Edit Drives," then press ENT.
Use the up or down arrow keys to scroll down the list of connected drives’ information
screens.
You may first examine whether there is any drive installed but not shown here. If there is a
drive installed but not listed, the drive may be defective or not installed correctly. Please
check your enclosure installation and contact your system vendor.
Press ENT on a drive. Choose "View Drive Information" by pressing ENT. Use the up or down
arrow keys to navigate through the screens.
The Revision Number of the selected drive will be shown. Press the down arrow key to see
other information.
Other information screens include "Serial Number" and "Disk Capacity" (displayed in blocks;
each block equals 512K Bytes).

NOTICE!
• Drives of the same brand/model/capacity might not feature the same block number.
• The basic read/write unit of a hard drive is a block. If members of a logical drive have dif-
ferent block numbers (capacity), the smallest block number will be taken as the maxi-
mum capacity to be used in every drive. Therefore, use drives of the same capacity.
• You may assign a Local/Global Spare Drive to a logical drive whose members have a block
number equal to or smaller than the Local/Global Spare Drive but you should not do the
reverse.
