When read and write disk is damaged, the video data is lost, you can access to backup video
data from a redundant disk. Need to remove the damaged hard disk after the first shutdown,
and then power the system back into the "main menu"-"storage management", redundant disk
set to read/write disk.

6.7 Hard S.MA.R.T technology
SMART's called the "Self-Monitoring Analysis and Reporting Technology", that "
self-monitoring , analysis , and reporting technology。Support HDD S.M.A.R.T technology
available through hard disk monitoring on instruction and monitoring software on the host
running heads, platters, motors, circuits, historical records and preset security analysis,
comparing the values. When there is a safety value outside the range, it will automatically
warn the user. Seagate hard drive S.M.A.R.T test parameters, for example, specific analysis
of main parameters mean. S.M.A.R.T test parameters are divided into 7 columns, namely ID
detection code, property descriptions, threshold value, property value, the maximum error
value, actual value, and property status.
1. ID detection code
ID detection code is not the only, vendors as needed, using different ID code or how much
increase or decrease depending on the detecting parameter ID code number. For example,
Western Digital's product ID code to "04", test parameter is Start/Stop Count (number of
power), while Fujitsu companies the same code parameters for "Number of times the spindle
motor is activated" (motor activation time).
2. Attribute name
Property name that describes the test items, can be customized by the manufacturer increase
or decrease, since ATA standards are constantly updated, and sometimes different models of
the same brand products will vary. But several major provisions must ensure that the
S.M.A.R.T test items (although different manufacturers for test items have specific naming
conventions, but the essence of these monitoring projects are the same).
3. Read Error Rate
4. Spin up Time
8. Start/Stop Count
9. Relocated Sector Count
10. Seek Error Rate
11. Power-on Hours Count
10. Spin up Retry Count
194 Power temperature
195 ECC on the Fly count
197 Current Pending Sector Count
198 Off-line Scan Incorrect Sector Count
199 Ultra ATA CRC Error Rate Ultra DMA
