Hard Drive Configuration and Maintenance
It is recommended that you start with a newly 
formatted external or secondary internal audio 
drive. You should also periodically defragment 
your audio drive to ensure continued system 
performance.
Avoid Recording to the 
System Drive
Recording to your system drive is not recom-
mended. Recording and playback on a system 
drive may result in lower track counts or fewer 
plug-ins.
Supported Drive Formats and 
Drive Types
Drive Formats
Windows Windows XP systems should use drives 
formatted as NTFS only. 
Mac Mac systems should use drives formatted 
with HFS or HFS+ file system only.
Hard drive performance depends on factors in-
cluding system configuration, number of tracks, 
session sample rate, density of edits, and the use 
of crossfades and other processes such as Beat 
Detective in a session. 
For complete hard drive requirements, see the 
Digidesign website (www.digidesign.com).
SCSI Hard Drives
Digidesign recommends qualified SCSI hard 
drives and a qualified SCSI host bus adapter 
(HBA) card or (on Windows systems) a qualified 
built-in SCSI HBA connector on the mother-
board.
For complete information on track count and 
the supported number and configuration of 
SCSI drives, visit the Digidesign website 
(www.digidesign.com).
Always back up any important data on your 
drive before formatting it, as it will erase all 
data on the drive.
Windows systems can also support Mac 
drives formatted using the HFS+ system 
(also commonly referred to as Mac OS Ex-
tended). Refer to the Pro Tools Reference 
Guide for more information.
HFS drives are supported as Transfer drives 
only.
For more information, see Appendix A, 
“Connecting SCSI Drives.”
