(24) FLUSH CACHE (X’E7’)

This command is used to order to write every write cache data stored by the device

into the medium. BSY bit is held at "1" until every data has been written normally

or an error has occurred. The device performs every error recovery so that the data

are read correctly.

When executing this command, the reading of the data may take several seconds if

much data are to be read.

In case a non-recoverable error has occurred while the data is being read, the error

generation address is put into the command block register before ending the

command. This error sector is deleted from the write cache data, and the remaining

cache data is written into the medium by the execution of the next Flush Cache

command.
