What are the limitations of fat fat32 and ntfs?
FAT:The 4-GB partition limit is imposed by the maximum number of clusters and the largest cluster size supported by the FAT file system. In Windows XP, FAT16 is limited to 64K clusters. Multiply the maximum number of clusters (64k) by the maximum cluster size (64K), and the result is 4GB. In addition to Windows XP, Microsoft Windows 2000 and Microsoft Windows NT 4.0 also support FAT16 volumes up to 4GB in size.FAT16 volumes larger than 2GB are not accessible from computers running Microsoft Windows Millennium Edition (Me), Windows 98, Windows 95, or MS-DOS. The size limit for FAT16 volumes in these operating systems is 2 GB. In other words, to maintain compatibility with Windows Me, Windows 98, Windows 95, or MS-DOS, a volume cannot be larger than 2 GB. For additional information about FAT16 drive and partition size limits in Windows Me, Windows 98, Windows 95, and MS-DOS, click the article numbers below to view the article in the Microsoft Knowledge BaseFAT32:Clusters cannot be 64 kilobytes (KB) or larger. If clusters were 64 KB or larger, some programs (such as Setup programs) might calculate disk space incorrectly.A volume must contain at least 65,527 clusters to use the FAT32 file system. You cannot increase the cluster size on a volume using the FAT32 file system so that it ends up with less than 65,527 clusters.The maximum possible number of clusters on a volume using the FAT32 file system is 268,435,445. With a maximum of 32 KB per cluster with space for the file allocation table (FAT), this equates to a maximum disk size of approximately 8 terabytes (TB).The ScanDisk tool included with Microsoft Windows 95 and Microsoft Windows 98 is a 16-bit program. Such programs have a single memory block maximum allocation size of 16 MB less 64 KB. Therefore, The Windows 95 or Windows 98 ScanDisk tool cannot process volumes using the FAT32 file system that have a FAT larger than 16 MB less 64 KB in size. A FAT entry on a volume using the FAT32 file system uses 4 bytes, so ScanDisk cannot process the FAT on a volume using the FAT32 file system that defines more than 4,177,920 clusters (including the two reserved clusters). Including the FATs themselves, this works out, at the maximum of 32 KB per cluster, to a volume size of 127.53 gigabytes (GB).You cannot decrease the cluster size on a volume using the FAT32 file system so that the FAT ends up larger than 16 MB less 64 KB in size.You cannot format a volume larger than 32 GB in size using the FAT32 file system in Windows 2000. The Windows 2000 FastFAT driver can mount and support volumes larger than 32 GB that use the FAT32 file system (subject to the other limits), but you cannot create one using the Format tool. This behavior is by design. If you need to create a volume larger than 32 GB, use the NTFS file system instead.NTFS:File NamesFile names are limited to 255 UTF-16 code words. Certain names are reserved in the volume root directory and cannot be used for files. These are: $MFT, $MFTMirr, LogFile, Volume, AttrDef, . (dot), Bitmap, Boot,BadClus, $Secure, Upcase, and Extend; . (dot) and $Extend are both directories; the others are files. The NT kernel limits full paths to 32,767 UTF-16 code words.Maximum Volume SizeIn theory, 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. For example, using 64 KB (64 × 1024 bytes) clusters, the maximum Windows XP NTFS volume size is 256 TB (256 × 10244 bytes) minus 64 KB. 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 (128 × 10243 bytes) 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 EFI and 64-bit support.[44]Maximum File SizeAs designed, the maximum NTFS file size is 16 EB (16 × 10246 bytes) minus 1 KB (1024 bytes) or 18,446,744,073,709,550,592 bytes. As implemented, the maximum NTFS file size is 16 TB (16 × 10244 bytes) minus 64 KB (64 × 1024 bytes) or 17,592,185,978,880 bytes.Alternate Data StreamsWindows system calls may handle alternate data streams. Depending on the operating system, utility and remote file system, a file transfer might silently strip data streams. A safe way of copying or moving files is to use the BackupRead and BackupWrite system calls, which allow programs to enumerate streams, to verify whether each stream should be written to the destination volume and to knowingly skip offending streams.

What exactly is a cluster as a unit of computer disk space?
As described here, the smallest unit of space on the hard disk that any software can access is the sector, which contains 512 bytes. It is possible to have an allocation system for the disk where each file is assigned as many individual sectors as it needs. For example, a 1 MB file would require approximately 2,048 individual sectors to store its data. Under the FAT file system (and in fact, most file systems) individual sectors are not used. There are several performance reasons for this. It can get cumbersome to manage the disk when files are broken into 512-byte pieces. A 2 GB disk volume using 512 byte sectors managed individually would contain over 4 million individual sectors, and keeping track of this many pieces of information is time- and resource-consuming. Some operating systems do allocate space to files by the sector, but they require some advanced intelligence to do this properly. FAT was designed many years ago and is a simple file system, and is not capable of managing individual sectors. What FAT does instead is to group sectors into larger blocks that are called clusters, or allocation units. The cluster size is determined primarily by the size of the disk volume: generally speaking, larger volumes use larger cluster sizes. For hard disk volumes, each cluster ranges in size from 4 sectors (2,048 bytes) to 64 sectors (32,768 bytes). Floppy disks use much smaller clusters, and in some cases use a cluster of size of just 1 sector. The sectors in a cluster are continuous, so each cluster is a continuous block of space on the disk. Cluster sizing (and hence partition or volume size, since they are directly related) has an important impact on performance and disk utilization. The cluster size is determined when the disk volume is partitioned. Certain utilities (like Partition Magic) can alter the cluster size of an existing partition (within limits) but for the mostpart, once the partition size is selected it is fixed. Every file must be allocated an integer number of clusters--a cluster is the smallest unit of disk space that can be allocated to a file, which is why clusters are often called allocation units. This means that if a volume uses clusters that contain 8,192 bytes, an 8,000 byte file uses one cluster (8,192 bytes on the disk) but a 9,000 byte file uses two clusters (16,384 bytes on the disk). This is why cluster size is so important in making sure you maximize the efficient use of the disk--larger cluster sizes result in more wasted space. answer courtesy of: storageview.com (author Charles M.

What are differences between fat fat16 fat32 and ntfs?
A file allocation table (FAT) is a table that an operating system maintains on a hard disk that provides a map of the clusters (the basic unit of logical storage on a hard disk) that a file has been stored in. When you write a new file to a hard disk, the file is stored in one or more clusters that are not necessarily next to each other; they may be rather widely scattered over the disk. A typical cluster size is 2,048 bytes, 4,096 bytes, or 8,192 bytes. The operating system creates a FAT entry for the new file that records where each cluster is located and their sequential order. When you read a file, the operating system reassembles the file from clusters and places it as an entire file where you want to read it. For example, if this is a long Web page, it may very well be stored on more than one cluster on your hard disk. Until Windows 95 OSR2 (OEM Release 2), DOS and Windows file allocation table entries were 16 bits in length, limiting hard disk size to 128 megabytes, assuming a 2,048 size cluster. Up to 512 megabyte support is possible assuming a cluster size of 8,192 but at the cost of using clusters inefficiently. DOS 5.0 and later versions provide for support of hard disks up to two gigabytes with the 16-bit FAT entry limit by supporting separate FATs for up to four partitions. With 32-bit FAT entry (FAT32) support in Windows 95 OSR2, the largest size hard disk that can be supported is two terabytes! However, personal computer users are more likely to take advantage of FAT32 with 5 or 10 gigabyte drives. NTFS (NT file system) is the system that the Windows NT operating system uses for storing and retrieving files on a hard disk. NTFS is the Windows NT equivalent of the Windows 95 FAT (file allocation table) and the OS/2 HPFS (high performance file system). However, NTFS offers a number of improvements over FAT and HPFS in terms of performance, extendibility, and security. Notable features of NTFS include: Use of a b-tree directory scheme to keep track of file clusters Information about a file's clusters and other data is stored with each cluster, not just a governing table (as FAT is) Support for very large files (up to 2 to the 64th power or approximately 16 billion bytes in size) An access control list (ACL) that lets a server administrator control who can access specific files Integrated file compression Support for names based on Unicode Support for long file names as well as "8 by 3" names Data security on both removable and fixed disks How NTFS Works When a hard disk is formatted (initialized), it is divided into partitions or major divisions of the total physical hard disk space. Within each partition, the operating system keeps track of all the files that are stored by that operating system. Each file is actually stored on the hard disk in one or more clusters or disk spaces of a predefined uniform size. Using NTFS, the sizes of clusters range from 512 bytes to 64 kilobytes. Windows NT provides a recommended default cluster size for any given drive size. For example, for a 4 GB (gigabyte) drive, the default cluster size is 4 KB (kilobytes). Note that clusters are indivisible. Even the smallest file takes up one cluster and a 4.1 KB file takes up two clusters (or 8 KB) on a 4 KB cluster system. The selection of the cluster size is a trade-off between efficient use of disk space and the number of disk accesses required to access a file. In general, using NTFS, the larger the hard disk the larger the default cluster size, since it's assumed that a system user will prefer to increase performance (fewer disk accesses) at the expense of some amount of space inefficiency. When a file is created using NTFS, a record about the file is created in a special file, the Master File Table (MFT). The record is used to locate a file's possibly scattered clusters. NTFS tries to find contiguous storage space that will hold the entire file (all of its clusters). Each file contains, along with its data content, a description of its attributes (its metadata). To go from 95 to NT, you will need to fdisk and delete your current partition unless it's already FAT16, make a new FAT16 partition and go about installing from there.
