CS609 System Programming GDB Solution Spring 2014

Increase in NTFS cluster size will decrease the volume size. Support or contradict this statement with proper logic.
Solution:

The maximum NTFS volume size is 264−1 clusters. However, the maximum NTFS volume size as implemented in Windows XP Professional is 232−1 clusters partly due to partition table limitations. For example, using 64 kB clusters, the maximum Windows XP NTFS volume size is 256 TBs minus 64 KBs. Using the default cluster size of 4 kB, the maximum NTFS volume size is 16 TB minus 4 kB. (Both of these are vastly higher than the 128 GB limit lifted in Windows XP SP1.) Because partition tables on master boot record (MBR) disks only support partition sizes up to 2 TB, dynamic or GPT volumes must be used to create NTFS volumes over 2 TB. Booting from a GPT volume to a Windows environment requires a system with UEFI and 64-bit support.

The maximum theoretical file size on NTFS is 16 EB (16 × 10246 or 264 bytes) minus 1 kB or 18,446,744,073,709,550,592 bytes. With Windows 8 and Windows Server 2012, the maximum file size implemented is 256 TB minus 64 KB or 281,474,976,645,120 bytes. NTFS supports a maximum cluster size of 64 kB.
