5.0 Data integrity The drive retains recorded information under all non-write operations. No more than one sector will be lost by power down during write operation while write cache is disabled. If power down occurs before completion of data transfer from write cache to disk while write cache is enabled, the data remaining in write cache will be lost. To prevent this data loss at power off, the following action is recommended: ! Confirm successful completion of SYNCHRONIZE CACHE (35h) command. 5.1 Equipment status Equipment status is available to the host system any time the drive is not ready to read, write, or seek. This status normally exists at power-on time and will be maintained until the following conditions are satisfied: ! Access recalibration/tuning is complete. ! Spindle speed meets requirements for reliable operations. ! Self-check of drive is complete. Appropriate error status is made available to the host system if any of the following condition occurs after the drive has become ready: ! Spindle speed goes outside of requirements for reliable operation. ! "Write fault" is detected. 5.2 Error recovery procedure Errors occurring with the drive are handled by the error recovery procedure. Errors that are uncorrectable after application of the error recovery procedures are reported to the host system as non-recoverable errors. Ultrastar 146Z10 hard disk drive specifications 17
