TeraStation User Manual
RAID Scanning is the feature to read check for all sectors in the data area of hard
drives which build RAID 1, 5 and 10.
An error possible to repaired* (bad sectors) which is found during check will be
automatically repaired.
Also an error possible to repaired* which is found during standard file operations will
be automatically repaired regardless of performing RAID Scanning or not.
Status Descriptions
Recoverable errors* • Read error in the data area which are build in RAID 1, 5, or
10 (including RAID 1 system area)
Unrecoverable errors • Write Error
• RAID management area error
• Drive partition information area error
• Drive recognition failure, etc.
If many errors possible to repair *(bad cluster) are found in one of the hard drives
which build RAID, that drive will be removed and the system will automatically move
to degrade mode.
Data are not protected in the degrade mode, it is strongly recommended to
immediately replace the erroneous hard drive.
When running RAID Scanning in the first time, it is strongly recommended to backup
data on the TeraStation in advance.
