Using your LinkStation
LinkStation User Manual
91
Several RAID modes are available for LinkStation models with multiple hard drives. LinkStations
with only one hard drive do not support RAID modes.
Notes:
• Not all LinkStations support RAID arrays. Check the LinkStation Function List on page 35 to see if
your LinkStation supports RAID arrays.
• All data is lost when the RAID mode is changed. Back up any important data before changing
RAID modes.
• In this document, “Recovery” means putting the LinkStation back to the state it was in before the
malfunction happened. It does not mean reading data from broken hard drives.
• When the RAID mode is changed, all data on the drives is lost. Before changing RAID modes,
please back up any important data from the array.
• RAID 1 mode
Uses 2 hard drives in a mirrored array. One drive’s worth of space is usable. Identical data is written
to both drives. If one drive is damaged, data can be recovered by replacing the damaged drive.
Note: Hard drives in the LS-WSXL LinkStation are not user-replaceable. If you experience a drive
failure with this model, contact Buffalo tech support for assistance.
• RAID 0 mode (LS-QVL, LS-WVL, LS-WXL, and LS-WSXL Default Setting)
Multiple hard drives are combined into a single array. The total capacity of all drives is usable. If any
drive is damaged, all data on the array is lost.
• Normal Mode
Each drive is accessible as a separate, individual drive. The total capacity of each drive is usable.
If any drive is damaged, all data on that drive is lost.
