When the unrecoverable error occurs during the write operation, the command execution is stopped. Then, when the drive receives the next command, it generates an interrupt of abnormal end. However an interrupt of abnormal end is not generated when a write automatic assignment succeeds. However, since the host may issue several write commands before the drive generates an interrupt of abnormal end, the host cannot recognize that the occurred error is for which command generally. Therefore, it is very hard to retry the unrecoverable write error for the host in the write cache operation generally. So, take care to use the write cache function XQJ+DQV9lJ66ROOHQWXUD61 RXQJXQJ3R*X6HRXO5HSXEOLFRI.25$RQJZDON5RDG6WRFNOH\3DUN8EULGJH UDQNIXUWHU5LQJ0QFKHQ*50$15HDGHU&RPPHQWRUP 8-,768/,0,7
