Storage
Disks
Format Disk Formatting a drive or array will erase all volumes on the drive or array. After formatting a
disk from the conguration utility, you must allocate a partition and format it before it is
usable. Use “Disk Management” to allocate a partition and format it.
Checking “Encryption” before formatting encrypts the drive or array with 128 bit AES
encryption. Only the TeraStation will be able to read the disk after that. To unencrypt the
hard drive, uncheck “Encryption” and format it again.
Remove Disk Before physically removing a drive from the TeraStation, select the drive and click “Remove
Disk" to dismount the disk. It’s then safe to remove it.
Rediscover Disk After dismounting and removing a disk, click here to have the TeraStation recognize a
replacement drive without restarting the TeraStation.
RAID
Array
RAID Array By default, the TeraStation is in RAID 5 mode. You may congure any of the following
RAID modes: “RAID5”, “RAID1”, “RAID10”, and “RAID0”.
To congure a RAID array, check the hard drives to use, select RAID mode, and click “Create
Raid Array”.
• To build a RAID 1 array, check 2 drives.
• To build a RAID 10 or RAID 0 array, check all drives.
• To build a RAID 5 array, check 3 or 4 drives.
• To delete an array, click “Delete RAID Array”.
Changing RAID modes will erase all data on the array. Back up any important data before
changing the RAID mode.
If you have a leftover drive after building a RAID 5 array with 3 drives, or a RAID 1 array,
it can be set as a hot spare by clicking “Set to spare-disk”. Click “Set to normal disk” to
change it back to a normal drive.
