Drive Replacement for a RAID 0 Array

If a drive used in a RAID 0 array fails, you need to delete the RAID array, format the replaced drive, then create a RAID

0 array again after replacing the defective drive to a new drive.

Note: If a drive malfunctions in a RAID 0 array, all data on the RAID array will be lost. All of the settings for the shared

folders (such as access restrictions) are erased after replacing a drive from a RAID 0 array.

1 Turn off the TeraStation.
