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. C141-E120-02EN 5-83

Error information
(36)
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 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.
