In banded recording, the disk is divided into multiple bands (also called partitions,
notches, or bit-zoned areas). Starting at the inner band, each band further out has
more bl ocks per tr ack (a h igher recordi ng fr equency). Thi s use of multip le-fre quency
recording increases the capacity of the drive.
Maxtor has incorporated a number of unique options into the drive. The Maxtor
(Vendor) Special Function Control page is used to control these options. The options
include:
•Initiate Synchronous Data Transfer Negotiation - a toggle-type
parameter that allows the initiator to move between asynchronous and
synchronous modes of data transfer.
•Write Protect - Prevents writing to the disk drive.
•Spin Delay - specifies if the drive should spin-up at power on or wait for
a START STOP UNIT command from the host.
•Stagger Spin Delay - allows a series of drives to be spun up individually,
reducing the load on the system power supply.
Th e Maxt o r A tlas 10K II I ha rd disk d ri v es have th ree bas i c power s tat e s:
•OFF - power is removed from the drive.
•U NIT READY - the drive is powered on an d is ready to accept and
execute commands. A single sub-state of UNIT READY exists,
ACTIVE. This is the highest power consumption state of the drive. A
media access command is acted upon immediate ly by the drive.
The drive remains in the UNIT READY state.
•NOT READY - The drive is power ed on but c a nnot be addr e ssed. An
example of this state is during spin-up. In other cases the drive may
require operator intervention. This state will return a Status = Check
condition.
The Power Condition Page, controlled with the MODE SELECT command, sets the
drive Power Management functions. This page is not changeable.
The drive has extensive diagnostic capabilitie s, including those described below:
power- on self- test, peri odic sel f-adjustmen ts, and hos t diagnostics. Maxto r uses self-
diagnostic tests and sense data tracking to manage drive errors, in addition to logical
block address (LBA) revectoring.
