Advanced Product Features

3.13. Zoned Recording

The drives employ zoned recording to increase data density on the outer tracks of the drive. Zoned recording allows the adjustment of the number of sectors per track, which provides storage of more sectors on the larger, outer tracks. Formatting packs data uniformly throughout the surface of the platter by dividing the outer tracks into more sectors. With more bytes per track, the drive reads the data in the outer zones at a faster rate.

3.14. Headerless Format

Headerless format is also known as ID-less or No-ID sector format. This format removes the header (or ID fields) and all the information within the header (track format) to provide a dramatic increase in user capacity. Our advanced, integrated SCSI controller assumes the task of determining the physical location of each sector.

3.15. LED Support

If an LED is installed on the drive, the following occurs:

The LED is turned off as soon as power is applied. If Auto Start is enabled, the LED is on while the drive is spinning up and turned off when Auto Start is completed.

￿￿The LED is on when a SCSI command is being executed.

The LED flashes when an error prohibits the use of the SCSI interface.
