TeraStation IS Setup Guide
A RAID scan read checks all sectors in the data area of drives in an array. If a bad sector error
is found during the scan, it is repaired automatically. Note that some kinds of errors are
repaired automatically by the array even without a RAID scan.
Status Descriptions
repair possible • Read error in the data area of array
impossible to repair • Write Error
• RAID management area error
• Drive partition information area error
• Drive recognition failure, etc.
If many repairable errors are found in one drive, that drive is removed from the RAID and the
system will automatically move to degraded mode. The system will continue to function, but
data is not protected in degraded mode, so the faulty drive should be replaced immediately.
Before running a RAID scan for the first time, back up your data.

RAID Array Error Detection Response
With a RAID 1, RAID 5, or RAID 10 array, you may choose to have the system shut down
automatically if an error is detected. This feature is not available for RAID 0 arrays or disks in
normal mode. By default, this is set to "Shutdown".
Boot with iSCSI service
After an error occurs, the iSCSI service may be enabled or disabled at the next boot. By
default, it will be disabled.
