Problem:
Older versions of Pro Tools® (version 8 and lower) do not support record or playback on disks larger than 2TB. If you attempt to record or playback from any locations on the disk above 2TB, Pro Tools will give errors. A disk larger than 2TB will work until it is filled to 2TB, then it will give errors. 6TB models will not work with Pro Tools 8 and lower.

Solution:
This problem has been fixed in Pro Tools 9 and higher. For Pro Tools 8 and lower, GT 062E models that are larger than 2TB, such as the 3TB and 4TB models, must be configured in RAID 1 mode. This is because RAID 1 presents the disk to the operating system as half the total capacity (1.5TB for the 3TB, and 2TB for the 4TB) making the volumes less than 2TB.
