Before You Begin
Thank you for your interest in Maxtor hard disk drives. This manual provides technical information for
OEM engineers and systems integrators regarding the installation and use of Maxtor hard drives. Drive
repair should be performed only at an authorized repair center. For repair information, contact the Maxtor
Product Support Center at 1-800-2MAXTOR.
CAUTION: Maxtor hard drives are precision products. Failure to follow these precautions and guidelines out-
lined here may lead to product failure, damage and invali
1 BEFORE unpacking or handling a drive, take all proper electro-static discharge (ESD) precau-
tions, including personnel and equipment grounding. Stand-alone drives are sensitive to ESD
damage.
2 BEFORE removing drives from their packing material, allow them to reach room tempera-
ture.
3 During handling, NEVER drop, jar, or bump a drive.
4 Once a drive is removed from the Maxtor shipping container, IMMEDIATELY secure the
drive through its mounting holes within a chassis. Otherwise, store the drive on a padded,
dation of all warranties.
grounded, antistatic surface.
5 NEVER switch DC power onto the drive by plugging an electrically live DC source cable into
the drive's connector. NEVER connect a live bus to the drive's interface connector.
6 ELECTRICAL GROUNDING - For proper operation, the drive must be securely fastened to a
device bay that provides a suitable electrical ground to the drive baseplate.
Please do not remove or cover up Maxtor factory-installed drive labels. They contain information required
should the drive ever need repair. Thank you for your interest in Maxtor hard disk drives. This
manual provides technical information for OEM engineers and systems integrators regarding
the installation and use of Maxtor hard drives. Drive repair should be performed only at an
authorized repair center. For repair information, contact the Maxtor Customer Service Center at 800-2MAXTOR or 1-303-678-2015.

3.2 UNPACKING INSTRUCTIONS
CAUTION: The maximum limits for physical shock can be exceeded if the
drive is not handled properly. Special care should be
taken not to bump or drop the drive. It is highly recommended
that MaXLine Plus II 250GB at drives are not stacked or placed
on any hard surface after they are unpacked. Such handling could
cause media damage.
1. Open the shipping container and remove the packing assembly that
contains the drive.
2. Remove the drive from the packing assembly.
CAUTION: During shipment and handling, the antistatic electrostatic dis-
charge (ESD) bag prevents electronic component
damage due to electrostatic discharge. To avoid accidental damage to the drive, do not use a sharp instrument to open the ESD
bag and do not touch PCB components. Save the packing materials for possible future use.
3. When you are ready to install the drive, remove it from the ESD bag.

Installation
The configuration of the following three jumpers controls the drive’s five modes of
operation:
• CS – Cable Select
• DS – Drive Select
• CLJ– Cylinder Limitation Jumper
The AT PCB has two jumper locations provided to configure the drive in a system.
The default configuration for the drive as shipped from the factory is with a jumper
across the CS location, and open positions in the DS and CLJ positions.
Table 3-1 defines the operation of the master/slave jumpers and their function
relative to pin 28 on the interface. 1 indicates that the specified jumper is installed;
0 indicates that the jumper is not installed.
Table 3-1 AT Jumper Options

0 0 X Drive is configured as a slave
1 0 Gnd Drive is configured as Master (Device 0) when
attached to the end of a 80 conductor Ultra ATA
cable
0 1 X Drive is configured as a Master
1 0 Open Drive is configured as a Slave (Device 1) when
attached to the middle of a 80 conductor Ultra ATA
cable
1 1 X Drive is configured as a Master with an attached slave
that does not support DASP
Note: In Table 3-1, a 0 indicates that the jumper is removed, a 1 indi-
cates that the jumper is installed, and an X indicates that the
jumper setting does not matter.
3.3.1.1 Cable Select (CS) Jumper
When a MaXLine Plus II 250GB AT hard disk drive and another ATA hard disk
drive are daisy-chained together, they can be configured as Master or Slave either by
the CS or DS jumpers. To configure the drive as a Master or Slave with the CS
feature, the CS jumper is installed (1). The drive's position on the 80 conductor Ultra
ATA data cable then determines whether the drive is a Master (Device 0) or a Slave
(Device 1). If the drive is connected to the end of the Ultra (cable Select) data cable
the drive is a Master. If the drive is connected to the middle connection it is set as a
Slave.
3-6 Maxtor MaXLine Plus II 250GB AT
Once you install the CS jumper, the drive is configured as a Master or Slave by the
state of the Cable Select signal: pin 28 of the ATA bus connector. Please note that
pin 28 is a vendor-specific pin that Maxtor is using for a specific purpose. More than
one function is allocated to CS, according to the ATA CAM specification (see
reference to this specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is
configured as a Master. If it is a 1 (high), the drive is configured as a Slave. In order
to configure two drives in a Master/Slave relationship using the CS jumper, you
need to use a cable that provides the proper signal level at pin 28 of the ATA bus
connector. This allows two drives to operate in a Master/Slave relationship
according to the drive cable placement.
The MaXLine Plus II 250GB AT hard disk drives are shipped from the factory as a
Master (Device 0 - CS jumper installed). To configure a drive as a Slave (Device 1DS scheme), the CS jumper must be removed. In this configuration, the spare
jumper removed from the CS position may be stored on the PK jumper pins.
3.3.1.2 Drive Select (DS) Jumper
You can also daisy-chain two drives on the ATA bus interface by using their Drive
Select (DS) jumpers. To use the DS feature, the CS jumper must not be installed.
To configure a drive as the Master (Device 0), a jumper must be installed on the DS
pins.
Installation
Note: The order in which drives are connected in a daisy chain has no
significance.
3.3.1.3 Master Jumper Configuration
In combination with the current DS or CS jumper settings, the Slave Present (SP)
jumper can be implemented if necessary as follows:
Note: The CS position doubles as the Slave present on this drive.
When the drive is configured as a Master (DS jumper installed or CS jumper
installed, and the Cable Select signal is set to (0), adding an additional jumper (both
jumpers DS and CS now installed) will indicate to the drive that a Slave drive is
present. This Master with Slave Present jumper configuration should be installed on
the Master drive only if the Slave drive does not use the Drive Active/Slave Present
(DASP–) signal to indicate its presence.

Installation
3.3.1.4 Cylinder Limitation Jumper (CLJ)
For user capacities below 66,055,248 sectors (32GB), inserting the CLJ jumper limits
the Number of Cylinders field 1 to a value of 16,383, as reported in IDENTIFY
DEVICE data word. This allows software drivers to determine that the actual
capacity is larger than indicated by the maximum CHS, requiring LBA addressing to
use the full capacity.
