When I first installed my Drobo on my Windows XP it created a 2Tb drive, and wouldn’t let me go any higher. What is the reason behind this limit?
NTFS even under XP supports 2 exabytes: http://en.wikipedia.org/wiki/NTFS and even with the default 4Kb cluster size it manages 16Tb-4Kb. Is the Drobo using 512-byte clusters? Will this change with drives using 4Kb sectors?
