Mounting Installation

Data loss

 

2-5

 

 

 

For MAS series, Reed Solomon codes are applied for their ECC.

 

 

The sector-data is divided into 4 interleaving sectors, and ECC is

 

 

performed in each sector where the maximum number of errors (up

 

 

to 5 byte) can be corrected. [Total maximum byte: 5 byte ×

4

 

 

(interleave) = 20 byte]

 

 

 

If the error of read sector keeps allowable error byte number,

 

 

correction is performed.

 

 

 

However, if error byte exceeds its allowable number, correction

 

 

may not be performed properly.

 

 

 

Hot temperature

 

5-1

 

 

 

 

To prevent injury, do not handle the drive until after the device has

 

 

cooled sufficiently after turning off the power. The DE and LSI

 

 

become hot during operation and remain hot immediately after

 

 

turning off the power.
