(36-4) SET MAX UNLOCK (F9)

(36-4) SET MAX UNLOCK (F9)

This command requests a transfer of a single sector of data from the host.

The password supplied in the sector of data transferred shall be compared with the stored SET MAX password.

If the password compare fails, then the device returns command aborted and decrements the unlock counter. On the acceptance of the SET MAX LOCK command, this counter is set to a value of five and shall be decremented for each password mismatch when SET MAX UNLOCK is issued and the device is locked.

When this counter reaches zero, then the SET MAX UNLOCK command shall return command aborted until a power cycle.

If the password compare matches, then the device shall make a transition to the Set_Max_Unlocked state and all SET MAX commands will be accepted.

Sequential hitHAP Completion of transferring requested data Hit data3 Full hit hit all Last position at previous read commandDAP Last position at previous read command HAP set to hit position for data transferRequested data to be transferred Partially hit dataLack data HAP stopped6.6 Write Cache When the write cache function is enabled, the transferred data from the host by the WRITE SECTORS is not completely written on the disk medium at the time that the interrupt of command complete is generated. 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 UDQNIXUWHU5LQJ0QFKHQ*50$1 RXQJXQJ3R*X6HRXO5HSXEOLFRI.25$RQJZDON5RDG6WRFNOH\3DUN8EULGJH XQJ+DQV9lJ66ROOHQWXUD618-,768/,0,7 5HDGHU&RPPHQWRUP
