SECTION 1
GENERAL DESCRIPTION AND .SPECIFICATIONS
1.1 GENERAL DESCRIPTION
The Quantum ProDrive Series™ is a family of ten hard disk drives using non-removable 3 1/2-inch rigid
disk platters as storage media. These drives feature formatted capacities ranging from 42 to 168 megabytes
and a variety
of interfaces. This manual covers the ProDrive™40S and ProDrive 80S, which feature the
industry-standard Small Computer System Interface (SCSI) host interface. The ProDrive 40S has 42
megabytes
of formatted capacity on two disks with three movable heads; the ProDrive 80S has 84
megabytes
of formatted capacity on three disks with six movable heads. These drives make optimum use of
powerful SCSI commands to provide maximum system performance. Media defects and error recovery are
efficiently managed within these products and can
be fully transparent to the user. The ProDri:ve Series
drives feature an innovative design using an integrated controller, minimum number of parts, and close
control
of product quality during manufacture. The result is low cost, high reliability products.
NOTE: Throughout this manual, ProDrive 40S/80S or ProDrive will refer to either the ProDrive
40S or the ProDrive 80S. ProDrive 40S and ProDrive 80S will be used to refer specifically
to the
42 and 84 megabyte versions, respectively.

Shock and Vibration
Table I-I lists specified levels for shock and vibration applied to any of the three mutually perpendicular
axes (the principal drive base axes). The term "operating" implies that the drive will be fully functional
while being subjected to the shock or vibration level listed during operation. "Non-operating" implies that
there will be no change in performance once the drive is powered up after being subjected to the listed shock
orvibration in the powered-down (non-operating) condition.

In addition, the ProDrive as packaged in the shipping container will withstand drops onto a concrete
surface from 48 inches on all surfaces, six edges and three comers. It will withstand vibration applied to
the container
of 0.5 G, 5-100 Hz (0 to Peak) and 1.5 G, 100-500 Hz (0 to Peak).

NOTES: Quoted seek times include head settling time but do not include command overhead or latency
time. Seek time is the time required for the actuator to seek and settle on track.
Seek times are measured by averaging 1000 seeks of the indicated length. Average seek time is
the average
of 1000 random seeks. In the rare occurrence of a seek error, any individual seek
may take up to 5 seconds for recovery.
Sequential head switch time is the time required for the head to move from the end
of the last
sector on a track to the beginning
of the next sequential sector, located on the next track, same
cylinder. This time is fixed by the track skewing feature
of the drive. (See Appendix B.)
Power-up time is the time from the supply voltages reach operating range to the time the drive
is able
to accept aU commands.
Nominal conditions are defined as 25
0 C ambient temperature, nominal supply voltages, and no
applied shock
or vibration. Worst case conditions are defined as worst case extremes of
temperature and supply voltages.

Media Quality
The ProDrive features defect management, which eliminates the need to manually identify defects. Defect
management
is completely transparent to the user. See Appendix C for a detailed description of the
ProDrive defect handling procedure and ECC (Error Correcting Code) capability.

Error rates are defined by Quantum as follows:
1) A data error is one (1) sector read incorrectly. Data error rates are defined as average rates measured
over at least 1000 different sectors under any
of the specified operating conditions except applied
shock or vibration.
2) Random errors are those which do not exhibit a repeating error pattern, i.e .• the error does not occur
twice in a row within a specified number
of retry reads; the default is eight. (Retries are terminated
once data
is read correctly.) The sectors will not be automatically reallocated since the errors are
probably not due to media defects. See Appendix C for information on defect handling.
3) Defect errors are those which exhibit a repeating error pattern, i.e .• the error occurs twice in a row
within eight retry reads. and cannot be read without error up to that point. Such errors are likely due
to media defects. The sectors will be automatically reallocated
if the Automatic Read Reallocation
Enabled bit in page 1H and the Reallocate Uncorrectable Error Enabled bit in page 39H
of the
MODE SELECT command are set to 1. (The default is 0: automatic reallocation is not performed.)
See Appendix C for a description of error correction options.
4) Unrecoverable errors are those whose final retry error pattern is uncorrectable using ECC: retry reads
are terminated by either a repeating error pattern, or eight attempts without reading correctly.
5) A seek error is any seek
in which the drive does not locate the desired cylinder. or any seek in which
the drive must go through a full recalibration routine to locate the desired cylinder. A full
recalibration takes approximately five seconds.
