What is the biggest disk NT can use?
A. The simple answer to this question is that NT can view a maximum partition size of 2 terabytes (or 2,199,023,255,552 bytes), however there are limitations that restrict you well below this number. Both FAT and HPFS have internal limits of 4 GB due to the fact they use 32-bit fields to store file sizes. NTFS uses 64-bits for all sizes, leading to a max size of….. 16 exabytes!!! (18,446,744,073,709,551,616 bytes), however NT could not handle a volume this big. For IDE drives, the maximum is 136.9 GB, however for a standard IDE drive this is constrained to 528MB. The new EIDE drives can access much larger sizes. SCSI 2 has a maximum size of 7 gigabytes.
