I recently bought the WD Mybook Studio 2 with 4TB size (with RAID 0 configuration with HFS+ file system). I connected to my Mac Mini Power PC G4 with Tiger OS (10.4.11). It is very strange that I can only see 2TB of the disk not 4 but if I change the RAID configuration to RAID 1 I can see 1.86TB and if I took the drive to connect to my Window PC I can see it as 3.8TB. It seems like 2TB is the maximum size that my Mac mini can see, is there any possible way to solve this?? Please help.
