IDE/ATA Hard Drives
IDE/ATA drives meeting the requirements at this link are now qualified for
32 track performance with Mac TDM systems.
Drive Space Required
● Mono, 16-bit, 44.1 kHz audio requires approximately 5 MB/minute
disk space
● Mono, 24-bit, 44.1 kHz audio requires approximately 7.5
MB/minute disk space
Notes
● Pro Tools has a single audio file size limit of 2048MB, even when
used with Mac OS 9.x and the HFS+ file system. This equates to
about 4.5 hours at 24-bit, 44.1 kHz.
● High Speed Drives require manufacturer-approved enclosure to
ensure correct heat dissipation, required for sustained drive
reliability
● Pro Tools III Disk I/O: Wide drives require cable adapter, such as
Avid PN 0070-00469-01 (12" 50-pin female Centronics to 68-pin
male high-density)
● Pro Tools III Disk I/O: Some 3rd Generation LVD DigiDrives and
LVD hard drives from other storage manufacturers will not mount
when connected to a Pro Tools III Disk I/O. Digidesign has
confirmed that 3rd Generation LVD DigiDrives containing
mechanism model numbers beginning with "ST" will function
correctly. DigiDrives with mechanism model numbers beginning
with "D" will NOT function correctly. The DigiDrive's mechanism
model number can be viewed during initialization within your drive
formatting software. Note that the new 4th Generation
Ultra160/LVD DigiDrives do not have this incompatibility and are
qualified to work with Pro Tools III Disk I/Os.
