Data loss
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

( 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.
