Error information
(34) FLUSH CACHE (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 a 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.
Complete execution of this command may take 30 seconds or over.
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.
