Question : Problem: incorrect amount of disk space with RAID5

Hi. I need help for this one. I am using RAID5. When I am using 4 HDD with 500GB each, I get 1500GB which is correct. However, when I connect to 6 HDD with 500GB each, I only get 2199GB instead of 2500GB.

Does anyone know why?

Thank you in advance

Have you hit the 2TB NTFS 5 limit? If so, converting the disc to GPT will fix that. More information here: http://www.microsoft.com/whdc/device/storage/GPT-on-x64.mspx
