Having trouble getting a windows partitions bigger than 2 Terabytes? It all comes down to cluster size. For some reason my windows 7 is using 512 Byte cluster sizes. When formatting a drive you can change the cluster size to be much larger than 512 Bytes. They can be set up to 65,536 Bytes.
|Cluster size||Maximum NTFS Volume Size (bytes RAW)|
To format a volume with an 8192 Byte cluster, use the following command:
format d: /fs:ntfs /a:8192
Replace 8192 with the cluster size you wish to use.
These commands must be ran as Administrator.
To check the cluster size of your current drive volumes, use:
fsutil fsinfo ntfsinfo c:
Replace c: with the volume you wish to check.
