 There are three jumpers available for configuration of SCSI ID: E1,
 E2, and E3.

Delay Spin: A jumper in the DSPN (E4) location, disables spin up on
power-on. Disabling spin up on application of power can also be
enabled by setting the DSPN bit in MODE SELECT page 0.

Features

CONNER CFA-170S/340S PRODUCT MANUAL REV. A, 501-058, 10/1993

Overview of the Drives
----------------------
The Conner Filepro CFA-170S and CFA-340S are high performance, low-
profile hard disk drives that are designed to operate in a system
with a Small Computer System Interface (SCSI). The command set is
SCSI-2 compatible. The drives are actually two versions of the same
basic mechanism.

Features of the Drive
---------------------
- Can be installed in a wide range of host systems

- Supports SCSI-2 interface and commonly used SCSI-2 commands

 - High performance rotary voice coil actuator with embedded servo
   system

- One-of-seven run-length limited code

- High shock resistance

- Sealed head/disk assembly

- Internal air filtration

- Low power consumption

 - Automatic actuator latch over data-free landing zone during shut-
   down mode or power down

 - Microprocessor-controlled diagnostic routines are automatically
   executed at start-up

- 64K buffer

 - Reed-Solomon error detection and correction with on-the-fly single-
   burst correction

- Automatic error correction and retries, ECC on-the-fly

- 512-byte block size

- 10 MB/s synchronous or 5.0 MB/s asynchronous data transfer

- Read look-ahead buffering

Drive Motor and Spindle
-----------------------
A brushless DC direct-drive motor assembly is mounted on the drive's
base. The motor rotates the drive's spindle at 4,011 RPM. The motor/
spindle assembly is dynamically balanced to provide minimal
mechanical runout to the disks. A dynamic brake is used to provide a
fast stop to the spindle motor and return the heads to the landing
zone when power is removed.

Firmware
--------
The drive's firmware includes a command set that the host uses to
control the drive. The command set allows the host to request the
following types for actions:

- report drive status
- seek a specific point on the disk
- read and write data.

Error Correction
----------------
The drive uses a Reed-Solomon code to perform error detection and
correction. For each 512-byte block, the software error correction
poilynomial is capable of correcting:

- One error burst with of up to 22 bits

- Two error bursts of up to 11 bits each

Single bursts of 11 bits or less are corrected on the fly (OTF) with
no performance degradation.

Magnetic Field
--------------
The disk drive will meet its specified performance while operating in
the presence of an externally-produced magnetic field under the
following conditions:

Frequency Field Intensity
DC 6 gauss
To 700 kHz 7 milligauss
700 kHz to 1.5 MHz 3 milligauss

Acoustic Noise
--------------
The sound pressure level will not exceed 40 dBA in Idle Mode at a
distance of 1 meter from the drive.
