To list all mounted drives and their accompanying partitions from the Terminal on Mac OS X, you can use the diskutil command with the list flag.This approach will display all disks, drives, volumes, and containers on any drive connected to the Mac, including boot volumes, hidden volumes (like the Recovery partition), empty volumes, unformatted drives, and all other disks. In fact, the type of partition map makes almost no difference for non-bootable volumes. Thus, if a Mac owner does not plan to start Mac OS X or another operating system from the external hard drive, he or she can apply any type of the partition map without breaking the head against the wall. Several maps are available (e.g., APT, MBR, etc.). The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. Special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file. When this Reference Partition is activated, it changes its type into 1 (FAT12) and hides all other partitions by adding 0x10 to the type. Fe Linux Logical Volume Manager partition (old) This has been in use since the early LVM days back in 1997, and has now (Sept. 1999) been renamed 0x8e.

Below a list of the known partition IDs (system indicators)of the various operating systems, file systems, boot managers, etc.For the various systems, short descriptions are given,in the cases where I have some info.There seem to be two other major such lists: Ralf Brown's(see interrupt list under Int 19)and Hale Landis'but the present one is more correct and more complete.(However, these two URLs are a valuable source for other information.)See also the old Powerquest tableand thespecification for DOS-type partition tables.

To be precise: this is not used to designate unused areaon the disk, but marks an unused partition table entry.(All other fields should be zero as well.)Unused area is not designated. Plan9assumes that it can use everything not claimed for other systemsin the partition table.

DOS is a family of single-user operating systems for PCs.86-DOS (`QDOS' - Quick and Dirty OS) was a CP/M-like operatingsystem written by Tim Paterson of Seattle Computer Products (1979).Microsoft bought it, renamed it to MS-DOS 1.0 and sold it to IBM (1980)to be delivered together with the first IBM PCs (1981).MS-DOS 2.0 (1983) was rather different, and designed to be somewhatUnix-like. It supported a hard disk (up to 16MB; up to 32MB for version 2.1).Version 3.3+ added the concept of partitions, where each partition isat most 32MB. (Compaq DOS 3.31 relaxed this restriction.)Since version 4.0 partitions can be 512 MB.Version 5.0 supports partitions up to 2 GB.Several clones exist:DR-DOS(from Digital Research, later part of Novell and called NovellDOS orNDOS,then owned by Caldera and calledOpenDOS,then by its subsidiary Lineo who named it back to DR-DOS.See http://www.drdos.com/),PC-DOS(from IBM),FreeDOS, ...See Types of DOS.See comp.os.msdos.* andMSDOS partitioning summary.The type 01 is for partitions smaller than 16 MB.

Xenix is an old port of Unix V7.Microsoft Xenix OS was announced August 1980, a portable and commercialversion of the Unix operating system for the Intel 8086, Zilog Z8000,Motorola M68000 and Digital Equipment PDP-11.Microsoft introduces XENIX 3.0 in April 1983.(Timeline of Microcomputers)SCO delivered its first Xenix for 8088/8086 in 1983.See comp.unix.xenix.sco.

Matthias Paul writes: Some old DOS versions have had a bug which requires thispartition to be located in the 1st physical 32 MB of the hard disk, hencefor compatibility with these old issues, partitions located elsewhereshould better be assigned the ID FAT16B (06h).

Supports at most 8.4 GB disks: with type 05 DOS/Windows will not usethe extended BIOS call, even if it is available. See type 0f below.Using type 05 for extended partitions beyond 8 GB may leadto data corruption with MSDOS.

An extended partition is a box containing a linked list of logicalpartitions. This chain (linked list) can have arbitrary length, butsome FDISK versions refuse to make more logical partitions than thereare drive letters available (e.g. MS-DOS LASTDRIVE=26 is good for atmost 24 disk partitions; Novell DOS 7+ allows LASTDRIVE=32).

Partitions, or at least the FAT16 filesystems created on them,are at most 2 GB for DOS and Windows 95/98 (at most 65536 clusters,each at most 32 KB).Windows NT can create up to 4 GB FAT16 filesystems (using 64 KB clusters),but these cause problems for DOS and Windows 95/98.Note that VFAT is 16-bit FAT with long filenames; FAT32 is a differentfilesystem.

IFS = Installable File System. The best known example is HPFS.OS/2 will only look at partitions with ID 7 for any installedIFS (that's why the EXT2.IFS packet includes a special 'Linuxpartition filter' device driver to fool OS/2 into thinking Linuxpartitions have ID 07). (Kai Henningsen (kai@khms.westfalen.de))

Filesystem introduced in Windows NT 3.1.It is rumoured that the Windows NT boot partition must be primary,and within the first 2 GB of the disk.

Extended FAT, a.k.a. FAT64.Available in Microsoft Windows since CE 6.0 and Vista SP1.Allows 32 MB clusters and very large disks and files.

When it boots a DOS partition, OS/2 Boot Manager will hideall primary DOS partitions except the one that is booted,by changing its ID: 01, 04, 06 becomes11, 14, 16. Also 07 becomes 17.

(According to Matthias Paul.)

ID 12 (decimal 18) is used by Compaq for their configuration utilitypartition. It is a FAT-compatible partition (about 6 MB) that bootsinto their utilities, and can be added to a LILO menu as if it were MS-DOS.(David C. Niemi)Stephen Collins reports a 12 MB partition with ID 12 on a Compaq 7330T.Tigran A. Aivazian reports a 40 MB partition with ID 12 on a64 MB Compaq Proliant 1600.ID 12 is used by the Compaq Contura to denote its hibernation partition.(dan@fch.wimsey.bc.ca)

NCR has used ID 0x12 MS-DOS partitions for diagnostics andfirmware support on their WorldMark systems since the mid-90s.DataLight's ROM-DOS has replaced MS-DOS on more recent systems.Partition sizes were once 72M (MS-DOS) but are now 40M (ROM-DOS).

Intel has begun offering ROM-DOS based 'Service Partition' supporton many OEM systems. This support initially used ID 0x98 but hasrecently changed to ID 0x12. Intel provides their own support forthis partition in the form of a System Resource CD. Partition sizehas remained constant at 40M. See e.g.sds2.pdf.(Chuck Rouillard)

IBM also uses 0x12 for its Rescue and Recovery partition on Thinkpadlaptops. See alsothinkwiki.org.

Cody Batt (codyb@powerquest.com) writes:When a PowerQuestproduct likePartitionMagic orDrive Image makes changes to the disk,it first changes the type flag to 0x3C so that the OS won't try tomodify it etc. At the end of the process, it gets changed back towhat it was at first. So, the only time you should see a 0x3C type flagis if the process was interrupted somehow (power outage, user reboot etc).If you change it back manually with a partition table editor or somethingthen most of the time everything is okay.

A very old Unix-like operating system for PCs.

Ross Stell writes:The PICK multi-user operating system, developed in 1965 by Don Nelson andDick Pick to run on an IBM 360 mainframe and implemented during the 1970s bymany licensee companies on their minicomputers, was ported in 1983 by PICKSystems (http://www.marcomguy.com/pdf/CORP.PDF) to operate on the IBM PC-XTand later the AT and compatible PCs. This release is known as R83. Later(1989), PICK Systems produced Advanced PICK (AP) which operates within aWindows environment, thus obviating the need for a dedicated hard diskpartition.See also Wikipedia.

Very old FAQs recommended to use 41 etc instead of 81 etcon a disk shared with DRDOS because DRDOS allegedly disregardsthe high order bit of the partition type. (Or, rather, uses thehigh order bit to indicate that the partition is secured.)These types are not used anymore today.Roger Wolff (R.E.Wolff@BitWizard.nl) confirms:I remember installing DRDOS, and getting a few extra drive lettersthat I didn't expect. Turns out those are my Minix partitions.It is looking at them as a FAT filesystem. Looks like a big mess.After finding no other possibility than to just 'not touch those driveletters' I continue with the install. After a few minutes DRDOSautomatically decides to write a copy of the FAT into a file on oneof my MINIX partitions. Bye bye Minix partition.

SFS is an encrypted filesystem driver for DOS on 386+ PCs, writtenby Peter Gutmann.

If a partition table entry of type 0x42 is present in the legacypartition table, then W2K ignores the legacy partition tableand uses a proprietary partition table and a proprietary partitioningscheme (LDM or DDM). As the Microsoft KnowledgeBase writes:Pure dynamic disks (those not containing anyhard-linked partitions) have only a singlepartition table entry (type 42) to define theentire disk. Dynamic disks store their volumeconfiguration in a database located in a 1-MBprivate region at the end of each dynamic disk.

GoBackis a utility that records changes made to the disk,allowing you to view or go back to some earlier state.It takes over disk I/O like a Disk Manager would,and stores its logs in its own partition.

386BSD is a Unix-like operating system, a port of 4.3BSD Net/2to the PC done by Bill Jolitz around 1991. When Jolitz seemed tostop development, an updated version was called FreeBSD (1992).The outcome of a Novell vs. UCB law suit was that Net/2 containedAT&T code, and hence was not free, but that 4.4BSD-Lite was free.After that, FreeBSD and NetBSD were restructured, and FreeBSD 2.0and NetBSD 1.0 are based on 4.4BSD-Lite.FreeBSD runs on PCs. Seehttp://www.freebsd.org/FreeBSD.html.For NetBSD, see below - it changed partition type to a9.386BSD seems to be dead now.

Benedict Chong (bchong@blueskyinnovations.com) writes:BlueSky Innovations LLC does a boot manager productcalled Power Boot and we use, in addition,0C2h and 0C3h for hidden Linux partitions (swap and ext2fs).See also ID c2.

This ID may also be used in obscure trickery:on a shared MS-DOS / DR-DOS machine with DR-DOS 6.0-7.03 (so thatthe DR_DOS does not understand type 0f and the MS-DOSdoes not understand type c5) one may have two extendedpartitions, where each operating system sees only one.

DR-DOS 6.0 and higher (NetWare PalmDOS 1.0, Novell DOS 7, OpenDOS 7.01,DR-DOS 7.02+) will add 0xc0 to the partition type fora LOGIN.EXE-secured partition (so that people cannot avoidthe password check by booting from an MS-DOS floppy).Otherwise it seems that the types c1, c4, c5,c6 and d1, d4, d5, d6are used precisely like 01, 04, 05, 06(but are accepted only when booting from disk).

NTFS will add 0xc0 to the partition type for disabled partsof a Fault Tolerant set. Thus, one gets types c6, c7.See alsoWindows NT Boot Process and Hard Disk Constraints andSwitching from DR-DOS 6.0 to MS-DOS 5.0.
