5.3 Host Commands

(24) FLUSH CACHE (X’E7’)

This command is used to write every write cache data stored by the device into the medium. When the device completes all the data writing, it reports the status to the host system. The device performs every error recovery so that the data are read correctly.

When executing this command, the writing of the data may take several seconds if much data are to be written.

In case a non-recoverable disk write error has occurred while the data is being read, the error generation address is put into the shadow block register before ending the command. This error sector is deleted from the write cache data.
