These PC used a separate controller inserted in slot ISA with a transfer rate of 4.7 MB/s Since AT 80286-based computers, hard disks are IDE (also said read the Fat 16 and 32 partitions and create them with capacity

Windows NT 4.0 uses limited to 2.1 GB NTFS partitions and reads the FAT 16 (not the FAT32) partitions. The size of the sectors is also fixed: 4 KB for them were leaving 2000 and XP (limited to 2 terabytes in theory and Tera-byte 256 for not allow to create a partition larger than 32Īn NTFS partition is more based on clusters depending on the size of the partition but a master file table that is based on a description of files (location, attributes, user space quota for the users access rights.) and allows best protections of the files the user access level. In practice, Windows 98 agrees to create viaįDISK partitions up to 40 GB, 60 for Millennium. The theoretical maximum size is 2 Tetra Bytes (2000 GB). If Win95B can read the FAT16, DOS does not recognize FAT32 partitions. VFAT (for Virtual FAT) version used from Windows 95 so not DOS accepts long filenames and exceeds the limit of 8 characters, being compatible with the standardįAT 32 is used from Win95 OSR2 (Win95B) and is not compatible with the FAT 16. The capacity of each sector varies according to the size of the partition. The FAT 16 used DOS allows 2 GB max (main and logical) partitions. It is in version 16 from DOS 4.0 (early 1990s) and FAT12 for DOS 3.3 and It includes a table of contents that includes cluster by cluster the content. The FAT is a type of partition with NTFS. TheĭOS FDISK command to partition the hard disk, this command is directly integrated into the installer under 2000 XP, Vista. They are first format low-level in the manufacture (a program is downloadable on the sites of different manufacturers (specific for each) and in some cases repair bad sectors). Partition types for Windows.īefore you store information, a hard disk must be prepared. By dividing by 1000 * 1000 * 1000 (1000 is the Kilo used in hardware instead of 1024 used in software), there are 10,322 GB (detected by BIOS size: 10,241 GB). The boot sector is the one used to start the operatingĬapacity size of a disk hard is calculated by theĬapacity net = capacity of sectors (normally 512 Bytes) * nb. Each track is then divided in sectors of fixed size (usually 512Īnd finally, high level (for example, the Format command) formatting creates clusters in the areas of variable size depending on the partition type and the capacity of the hard disk. SCSI Servers disk spin at 10,000 or 15,000 same towers.Įach platter is divided into tracks of varying size depending on its location on the disk, most smaller towards theĬenter by formatting low-level in the manufacture. The current speed are 5400 (usually for Notebooks) and 7200 RPM depending on the model. If the hard drives of 1996 go around 13 ms, current standards arrive less than 8

With IDE controller, you can install 2 disks called master and slave via the water. Hard disk integrates an internal controller connected to the motherboard byĤ0 ou 80 pins (PATA) controller or an 8-pin (SATA) cable, they must be of the same type with ascending compatibility. IDE hard drives are used since the 80286 processor-based computers, even if the standard has since been improved several MFM and RLL usable only with the 8088 types are also past obsolete. SCSI controllers and hard disks will be seen in the second year. During the first year hardware, we see that the type IDE and SATA hard disks.
