Hard Drive Requirements
Older Power Macintosh Computers
Power Macintosh 9500 and 9600 computers
have two SCSI busses: an internal fast SCSI bus
and an external narrow SCSI bus. On these machines, sessions with higher track counts and
high edit density require a SCSI HBA card. For
optimum performance without a SCSI HBA
card, use the internal fast SCSI bus.
For audio recording and storage, all Pro Tools
TDM systems require one or more Digidesignqualified drives.
To provide full 64-track, 24-bit, 48 kHz performance, a TDM system must include at least two
Digidesign-qualified SCSI hard drives attached
to a qualified SCSI HBA (host bus adapter) card.
For 64-track sessions that have substantial edit
densities (such as one edit every third of a second across 64 voices) or large amounts of crossfades, up to four SCSI drives may be required, allocated with 16 tracks per drive and two drives
per SCSI channel.
Dedicated internal IDE/ATA drives can provide
32-track performance to all TDM systems.
Refer to the Digidesign Web site for compatible
hard drives and SCSI HBA cards:
www.digidesign.com/compato/
For higher track counts on Power Macintosh 9500, 9600, and Beige G3 computers, avoid using the external narrow SCSI
drive.
MIDI Requirements
Both USB and serial MIDI interfaces work effectively with Pro Tools. Serial MIDI interfaces offer the tightest possible MIDI timing.
Serial MIDI interfaces require either a Mac serial
port or a qualified modem-to-serial port adapter
(thereby not using a PCI slot). Refer to the
Digidesign compatibility page for supported
adapters:
www.digidesign.com/compato/

chapter 2
Connecting SCSI Drives
SCSI hard drives function as the recommended
recording media for Pro Tools TDM systems; it is
there that Pro Tools sessions and audio files are
kept.
Although Pro Tools will let you record to your
system drive, this is generally not recommended. Performance for recording and playback on system drives is worse than on non-system drives, resulting in lower track counts and
fewer plug-ins.
SCSI hard drives offer several advantages over
ATA/IDE drives. First, SCSI drives can be external and therefore provide portable audio storage
that is easily moved between systems. Second,
SCSI drives offer slightly better performance
when recording to large numbers of tracks; attempting to record to a large number of audio
tracks with an ATA/IDE drive will result in a
short delay before recording begins.
SCSI Requirements
High-Performance SCSI Drives and SCSI Host Bus Adapters
To provide full 64-track, 24-bit, 48 kHz performance, a Pro Tools TDM system must include at
least two Digidesign-qualified SCSI hard drives
attached to a qualified SCSI HBA host bus
adapter (HBA) card.
For 64-track sessions that have substantial edit
densities (such as one edit every third of a second across 64 voices) or large amounts of crossfades, up to four SCSI drives may be required, allocated with 16 tracks per drive and two drives
per SCSI channel.
SCSI drives must provide a data transfer rate of
at least 9 MB per second of sustained throughput.
Pro Tools 24 requires a MIX Farm card (or
the discontinued Pro Tools 24 Expansion
Kit) to support up to 64 tracks.
Refer to the Digidesign Web site for compatible
hard drives and HBA cards:
www.digidesign.com/compato/
Software RAID is not supported for audio
drives.
Older Macintosh Computers
Power Macintosh 9500 and 9600 computers
have two SCSI busses: an internal fast SCSI bus
and an external “narrow” SCSI bus. On these
machines, sessions with higher track counts and
high edit density require a SCSI HBA card. For
optimum performance without a SCSI HBA
card, use the internal fast SCSI bus.
For higher track counts on Power Macintosh
9500, 9600, and Beige G3 computers, avoid using the external narrow SCSI drive.

Using these guidelines:
• 64 mono tracks of 24-bit audio takes up about
480 MB of hard drive space per minute.
• 64 mono tracks of 16-bit audio takes up about
320 MB of hard drive space per minute.
• 32 mono tracks of 24-bit audio takes up about
240 MB of hard drive space per minute.
• 32 mono tracks of 16-bit audio takes up about
160 MB per minute.
A 9-gigabyte drive holds:
• 18 minutes of 64 tracks, 24-bit audio
• 28 minutes of 64 tracks, 16-bit audio
• 37 minutes of 32 tracks, 24-bit audio
• 56 minutes of 32 tracks, 16-bit audio
Distribute Audio Across Multiple Drives
For best recording and playback performance,
don’t record and play back all audio files in a
session from the same drive. Instead, use
Pro Tools disk allocation features to distribute
audio files between multiple SCSI drives. See the
Pro Tools Reference Guide for details.

Disk Space for Audio Tracks
Audio tracks recorded at 24-bit resolution at a
CD-fidelity sampling rate of 44.1 kHz require
about 7.5 MB of hard drive space per minute.
The same tracks recorded at 16-bit resolution require about 5 MB per minute. Stereo tracks will
require about twice as much hard drive space.

Separate Video and Audio Files
If you are working with imported movies, movie
files must reside on a different SCSI bus than audio files. If audio files reside on disks connected
to a SCSI HBA card, video data should reside on
drives connected to a different SCSI bus.
Dual-Channel SCSI HBA Cards
If you use a dual-channel SCSI HBA card, equally
allocate audio files to drives connected to each
of the two busses on the card for optimal performance.
Connecting SCSI Drives
To connect an external SCSI drive:
1 Turn off power to both the computer and the
hard drive.
2 Attach a SCSI cable from the SCSI port of the
hard drive to the SCSI port of the SCSI HBA card
or computer depending on your system’s SCSI
requirements.
3 Secure the cable’s connectors to the hard drive
and computer. Loose cables can cause data loss.
4 Connect additional drives by daisy-chaining
from one drive to another. Keep cable lengths to
a minimum (see Table 1).
5 Verify that the last SCSI device connected is
properly terminated. (See “SCSI Termination”
on page 7.)
6 Attach power cables to the hard drives.

Connecting an external SCSI hard drive
SCSI Termination
Your computer’s SCSI chain must be properly
terminated or your system will not function correctly. Only the last device on the chain should
be terminated using the termination type recommended by the hard drive manufacturer.
The drive should use either an external terminator plug or have its internal terminators enabled. If you are using a terminator plug, Digidesign recommends that you purchase and use an
active terminator.
Do not enable internal termination and install an external terminator plug on the
same drive. This will cause SCSI errors. See
your hard drive’s documentation for information regarding which type of termination
it uses.

Initializing and Maintaining SCSI Drives
SCSI hard drives used for audio recording on
TDM systems must be formatted (or initialized)
for either the HFS or HFS plus file system. Drive
partitions of up to 2 terabytes (2000 gigabytes)
can be used.
TDM systems require that you use the ExpressPro-Tools software from ATTO (included
with Pro Tools) for all drive formatting and partitioning; only one disk utility should be used
for all drives in a system.
To initialize a new drive:
1 Turn on your hard drives, computer, and any
other peripherals.
2 Use ATTO’s ExpressPro-Tools software version
2.3.2 to initialize and partition any new hard
drives.
Refer to the ExpressPro-Tools User’s Manual.
If you have existing FWB-formatted drives,
don’t install the ExpressPro-Tools extension; this can cause a conflict. This extension is not required to use the ExpressProTools software (to format new drives).
Formatting Drives
other details are written on the platters of the
hard drive in the form of a magnetic pattern. A
low-level format permanently erases all data on
the drive.
When is Low-Level Formatting Necessary?
Virtually all hard drives come pre-formatted
from the manufacturer. Low-level formatting is
generally unnecessary except in rare circumstances. They are:
◆ If you want to change the Block Size of the
drive. This is not recommended by Digidesign.
Digidesign systems only recognize 512-byte
blocks.
◆ If you want to perform permanent deletion of
data.
◆ If you want to clean a drive that is being mi-
grated from one operating system to another
(for instance, from UNIX to Macintosh).
Should you decide low-level formatting is necessary, keep in mind that it can take up to three
hours or more (depending on the size of the
drive). Avoid power interruptions and computer
bus resets during the format operation or permanent damage to the drive could occur. In addition, leave the drive powered on for at least 30
minutes prior to formatting so that the drive has
time to make any necessary thermal adjustments or recalibrations.
There are two different types of formatting:
high-level formatting and low-level formatting.
Low-Level (Physical) Formatting
Low-level formatting means completely erasing
the hard drive and rewriting each sector address
on the drive. In low-level formatting, the sector
and track addresses, error-correction codes, and
TDM Installation Guide8
High-Level Formatting (Initialization)
High-level formatting, or initializing a drive replaces the drive’s directory, volume partition
map and drivers. Information about the drive is
created and drivers that communicate this information to the host CPU are installed. The
drive itself is not erased, nor is verification performed.
When is High-Level Formatting Necessary?
It is generally necessary to initialize a hard drive
in one of the following cases:
◆ If a new drive is being prepared for use on a
computer for the first time and the drive is not
already initialized.
◆ If a drive is being changed from one platform
to another. For example if you are switching
from a Windows to a Macintosh-based system,
the drive must be reinitialized for the new operating system.
◆ If you suspect that the directories containing
the drive’s information have become corrupted.
Partitioning Drives
Partitioning divides a physical drive into multiple, unique volumes, almost as if you were creating virtual hard drives. Partitioning is usually
performed when the drive is initialized.
Mac OS 7.6.1 and above allows drives
larger than 4096 MB to be seen as whole
volumes. Drives must be initialized with
ExpressPro-Tools (or another utility) that
recognizes the 2 terabyte limit. Single files
cannot exceed 2048 MB in size.
Seek Times on Partitioned Drives
Seek times are actually faster on partitioned
drives (assuming that reads and writes are performed on a single partition), since the heads
only have to seek within the partition boundaries, rather than the whole capacity of the
drive.
In addition, smaller partitions perform faster
than larger partitions. However, this comes at
the expense of contiguous storage space. When
you partition a drive, you will need to find the
compromise that best suits your performance
and storage requirements.
Avoid distributing audio files within a session over different partitions on the same
drive since this will adversely affect drive
performance.
Avoiding File Fragmentation
For maximum recording and playback efficiency, data should be written to your hard
drive in a contiguous fashion—minimizing the
seek requirements to play back the data. Unfortunately, your computer can’t always store the
sound files in this way and must write to disk
wherever it can find space.
In multitrack recording, audio tracks are written
in discrete files, spaced evenly across the disk.
While fragmentation of individual files may be
zero, the tracks may be far enough apart that
playback will still be very seek-intensive. Also,
the remaining free space on the disk will be discontiguous, increasing the likelihood of file
fragmentation on subsequent record passes.
Increased fragmentation increases the chance of
disk errors, which can interfere with playback of
audio, and result in performance errors.
If Norton Utilities is used, it must be
Norton Utilities v4.0 or later to ensure
compatibility with HFS+ drives.
Chapter 2: Connecting SCSI Drives 9
Optimizing (Defragmenting) Drives
To prevent fragmentation, you can optimize
your drive, which rearranges your files into a
contiguous format. Most optimizing software
lets you run a check on a drive to find out the
percentage of fragmentation. If your drive
shows moderate to heavy fragmentation, you
should consider optimizing it.
If you use your system for intensive editing, or if
you frequently delete audio or fade files from
your hard drive, you may need to optimize your
drives on a weekly basis, or even every few days,
since it doesn’t take long for even a large hard
drive to become fragmented.
Backing Up Data Before Optimizing
Since your files will be rewritten by the optimization process, always make a backup copy of
the data on your hard drive before you optimize
it. You should also use a hard drive utility to
find and repair any problems before optimizing
data. If there is any damage to your hard drive's
directories prior to optimizing, serious data loss

For compatibility with Macintosh-based systems, Pro Tools for Windows lets you record and
play back sessions directly from a Macintoshformatted (HFS or HFS+) drive connected to a
Windows system. This functionality requires
that all Macintosh session and audio files be
stored on Macintosh-formatted drives.
For details on sharing sessions between Macintosh and Windows systems, see the Pro Tools Ref-
erence Guide.
Installing the MacOpener Utility
To use Macintosh-formatted HFS or HFS+ drives,
you will need to install the MacOpener software
utility. The MacOpener installer was placed on
your hard drive when you installed Pro Tools, in
the following location:
Program Files\Digidesign\Pro Tools Utilities\
MacOpener Demo
To Install MacOpener:
1 Locate the Setup.exe file in the above location
and double-click it to launch the installer.
2 Follow the on-screen instructions to install
MacOpener.
3 After installation is complete, restart your
computer.
Enabling the MacOpener Driver
After installing MacOpener, the MacOpener
driver must be enabled to mount HFS and HFS+
drives.
To enable the MacOpener Driver:
1 From the Start menu, choose Programs > Ma-
cOpener > MacOpener Driver Preferences.
2 Under Driver Settings, select Enable Mac-
Opener Driver.
3 Under Extension Mapping, select Do not add
the PC extension to the Mac file name.
To mount HFS or HFS+ drives on a Windows system, you must use the MacOpener
utility. A demo version of MacOpener is included with Pro Tools Windows.

software
Mounting an HFS Drive
If the MacOpener utility is installed and enabled, no additional steps are required to mount
HFS drives. They will appear as normal system
drives after you connect them and restart your
computer.
Formatting and Maintaining HFS (and HFS+) Drives
While it is possible to use MacOpener to format
HFS (and HFS+) drives from a Windows machine, this can yield unpredictable results. If
you need to format an HFS drive, connect it to a
Macintosh computer and use the ExpressProTools software from ATTO (included with
Pro Tools).
Don’t Use Windows Disk Utility Software on HFS Drives
Disk utility software for the Windows platform
(such as Norton Utilities for Windows) should
not be used on HFS drives. These utilities do not
recognize HFS-formatted drives and may try to
reformat them. This could cause format errors
on the HFS drive and result in data loss.
If you need to perform disk maintenance on an
HFS-formatted drive, connect the drive to a
Macintosh computer and use a Macintosh utility.

TDM Installation Guide14
Installing the Pro Tools Cards
Install the Pro Tools cards:
1 Turn off your computer and any peripherals.
Leave your computer’s power cable plugged in
so the computer is grounded.
2 Open the computer case. The illustrations in
this section show a Blue & White Macintosh G3
and a Macintosh 9600 computer. If you are using a different model, your installation should
be similar. For additional details on installing a
card in your computer, refer to its User’s Guide.
Before handling any card, discharge any
static electricity that may be on your clothes
or body by touching a grounded metal surface, such as the power supply case inside
your computer.
3 Remove the metal access port cover behind
the expansion slot you want to use by removing
the screw (if present) and sliding the cover out
from the access port.
4 Install the primary MIX Core or d24 card
(clock master with primary audio interface) in
the lowest numbered slot in your computer; to
determine which slot is the lowest, refer to “Determining Slot Order” on page 57.

5 Install the remaining Digidesign cards in suc-
cessive slots.
Pro Tools cards must be installed in a specific order that is dependent on the slot numbering of
the model of Macintosh you are using.
See Appendix A, “Determining Slot Order”
for details on determining slot order in your
Power Macintosh.
Chapter 3: Installing Pro Tools Hardware 15
Group similar cards together (put all MIX Farm
cards next to each other, for example).
Connecting Audio Interfaces
6 If installing a SCSI HBA card, install it in the
highest numbered remaining slot.
For 9500 and 9600 computers, the SCSI HBA
should reside before the video card.
Connect all TDM cards with the TDM ribbon cable:
1 Connect the first node of the cable to the first
TDM card. Make sure the TDM cable is facing
the right direction—align the white triangles on
the cable plug with the triangle on the card.
Attaching the TDM ribbon cable to MIX Core and
MIX Farm cards
2 Push down gently but firmly until the node is
fully connected to the card. When the plug is
properly seated, the two tabs on the side of the
cable’s TDM connector will click shut. To detach
the ribbon cable, squeeze the tabs on the TDM
connector inward.
3 Attach the remaining nodes on the TDM cable
to subsequent cards.
It is OK to have ribbon connectors that go
unused. They should reside after the last
TDM card.
Pro Tools provides you with a choice of the
888/24 I/O, 882/20 I/O,
1622 I/O, or ADAT
Bridge I/O interfaces. These devices supply the
inputs and outputs for your system.
For instructions on connecting an ADAT
Bridge I/O, see the ADAT Bridge I/O Installation Guide.
Connect the Pro Tools audio interfaces:
1 Connect the primary audio interface to the
primary Mix Core or d24 card with the provided
interface cable. The primary audio interface
functions as the clock master.
2 Connect additional audio interfaces to subse-
quent Digidesign audio cards.
If you are connecting both 888/24 and 882/20
or 1622 I/O Audio Interfaces to your system, for
best system performance, connect the 888/24 to
your core Pro Tools card, followed by any additional 888/24 interfaces to the next highest-priority cards. Then connect the 882/20 or
1622 I/O interfaces to subsequent cards.
You can use Digidesign’s 16-channel peripheral
cable adapter (optional) to connect two 8-channel audio interfaces to a single MIX Core, MIX
I/O, d24, or MIX Farm card.
