REGION: All
ISSUE: Replacing original TeraStation drive with a larger capacity drive
CAUSE: Faulty drive needs to be replaced.
PLATFORM: Terastation NAS
SOLUTION: It can be larger, but not smaller if it is part of a RAID1 or RAID5 array. The extra space in the case of a larger drive will not be added to the total volume of the TeraStation. If a smaller drive is used, Tera will reply with an error when an attempt to rebuild the RAID array. It can be larger or smaller if it is in Standard Mode or Spanning Mode.
