- Log onto the Terastation.
This login prompt will appear, enter admin for the user name.
Until you change it, the password for the admin account will be password. Press the OK button when finished.
User name: admin Password: password
- Click on Disk Management then RAID Configuration, configure the desired RAID setup. This page shows your current RAID arrays.
You may delete old arrays or create new ones by clicking on the underlined RAID Array # under RAID Array Configuration. You may also disable RAID Array Error Detection Response from this page.
Normally, this is set to automatically shut down the RAID array when an error is detected. Though it is not recommended, you may disable that behavior by clicking Disable and then Apply under RAID Array Error Detection Response.
Note that your TeraStation has four internal hard drives. Before creating a new RAID array, you may have to delete one or more pre-existing RAID Arrays to clear up the hard drives for your new one. This will destroy all data currently on the disks, so back up any important data before deleting RAID arrays. Whether you want to clear out an old array or create a new one, begin by clicking on the array underlined RAID Array #, under Name.
TeraStation uses RAID (Redundant Array of Independent Disks) technology to control the fourhard drives in your TeraStation.
RAID may be configured several ways:
RAID Spanning - All four drives are striped into one large drive, giving the maximum capacity for your TeraStation.
RAID 1 (mirroring) - Hard drives (or spanned pairs of hard drives) are arranged in mirrored pairs. Each half of the pair reads and writes exactly the same data.
RAID 5 (parity) - All drives in a RAID 5 array reserve part of their data space for parity information, allowing all data to be recovered if a single drive fails.
Buffalo Technology recommends RAID 5 for its excellent balance of efficiency and security.
- A configured RAID array may be deleted by pushing the Delete RAID Array button. This will free up all hard drives listed under Disk Structure.
- To configure an unconfigured array, put checks next to the hard disks you want included in the array (under Disk Structure) and choose your RAID mode. Click Setup RAID Array when ready. It may take several minutes to complete setting up the RAID array. When it is finished, a Disk Check will run.
- When RAID Configuration is done, you'll see this screen.
To configure a new array, click on RAID Array # and go back to step 2.
