Operations
(3) Status report in the event of an error
The status report concerning an error occurring during writing onto media is
created when the next command is issued. Where the command reporting the
error status is not executed, only the error status is reported. Only the status of an
error that occurs during write processing is reported.
<Exceptions>
The error status is not reported in the following case:
• The reset command is received after an error has occurred during writing to
media.
• Reset processing is performed as usual. The error status that has occurred
during writing to media is not reported.
(4) Enabling and disabling
Enabling and disabling of the Write Cache function can be set only with the SET
FEATURES command. The setting does not changed even when the error status
is reported.
The initial setting is stored in the system area of media. System area information
is loaded whenever the power is turned on.
(5) Reset response
When a reset is received while cached data is stored on the data buffer, data of the
data buffer is written on the media, and reset processing is then performed. This
is true for both a hard reset and soft reset.
(6) Caching function when power supply is turned on.
The caching function is invalid until Calibration is done after the power supply is
turned on (about 7 or 8 sec). It is effective in Default after that as long as the
caching function is not invalidly set by the SET FEATURES command.
