Interface
(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.
