Resetting the RAID Mode NOTE: This procedure destroys all RAID data. It should not harm individual drives or their contents; however, creating or running backups of all data is strongly recommended before proceeding. 1. Power down the unit and set the dip switch to the factory default setting (all switches OFF).

EZ Switch (SW1:2): The EZ (spare) switch inhibits spares when ON. When in the OFF position, all individual drives (not defined as members of an array) are considered spare. Should a RAID become degraded, when the EZ switch is in the OFF position a spare drive will be used automatically to rebuild the RAID, if present.

RAID 0 (Stripe set) Number of drives: at least 2 Unit capacity: size of each member times number of members. Spares: no Fault tolerance: none - if any member is lost all data is lost. RAID 0 “stripes” the file system across the array by placing sectors of data sequentially between drives in a specific order.

CLONE (Mirror set) Number of drives: at least 2 Unit capacity: size of one member. Spares: yes Fault tolerance: can withstand the loss of any number of drives without losing data as long as at least one complete member remains online. CLONE mode works the same way as RAID 1, by maintaining a complete copy of the entire set of data on each drive.
