Data loss
For MAP series, Reed Solomon codes are applied for their ECC. The
sector-data is divided into 6 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
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.
The main alert messages in the text are also listed in the "Important Alert Items."
