Reallocating Tracks
When opening a session where some of the
previously assigned hard drives are no
longer available (or don’t match the cur-
rent session platform), Pro Tools automati-
cally reassigns tracks to the volume where
the session file is stored. In such cases,
Pro Tools gives you the option of reallocat-
ing tracks to other drives.
Recording to the System
Volume
Though Pro Tools will let you record to
your system hard drive, this is generally
not recommended. Performance for audio
recording and playback on system drives is
worse than on non-system hard drives.
You should record to system drives only
when absolutely necessary—if your com-
puter system has just the one hard drive, or
if your other hard drives are completely out
of space.
Allocating Hard Drive
Space for Recording
The Operation Preference for Open Ended
Record Allocation determines how much
of your available hard drive space is allo-
cated for recording.
When this preference is set to Use All Avail-
able Space, the drive’s entire available
space is allocated. This can slow down the
recording process for hard drives that use
certain file systems, including HFS+ and
NTFS.
In such cases, you can reduce the time it
takes to begin recording by allocating only
a portion of your hard drive.
To allocate a portion of your hard drive for
recording:
1 Choose Setups > Preferences and click
Operation.
2 Under the Open Ended Record Alloca-
tion option, select Limit To and enter a
number of minutes to be allocated.
The number of minutes specified is allo-
cated for each record-enabled track. You
may find it necessary to experiment with
this number to achieve the desired perfor-
mance for recording.
3 When you are finished, click Done.
