NAME¶
disktype —
disk format detector
SYNOPSIS¶
DESCRIPTION¶
The purpose of
disktype is to detect the content format of a
disk or disk image. It knows about common file systems, partition tables, and
boot codes.
USAGE¶
disktype can be run with any number of regular files or device
special files as arguments. They will be analyzed in the order given, and the
results printed to standard output. There are no switches in this version.
Note that running disktype on device files like your hard disk will likely
require root rights.
See the online documentation at <
http://disktype.sourceforge.net/doc/> for
some example command lines.
The following formats are recognized by this version of
disktype.
- File systems:
- FAT12/FAT16/FAT32, NTFS, HPFS, MFS, HFS, HFS Plus, ISO9660,
ext2/ext3, Minix, ReiserFS, Reiser4, Linux romfs, Linux cramfs, Linux
squashfs, UFS (some variations), SysV FS (some variations), JFS, XFS,
Amiga FS/FFS, BeOS BFS, QNX4 FS, UDF, 3DO CD-ROM file system, Veritas
VxFS, Xbox DVD file system.
- Partitioning:
- DOS/PC style, Apple, Amiga "Rigid Disk", ATARI ST
(AHDI3), BSD disklabel, Linux RAID physical disks, Linux LVM1 physical
volumes, Linux LVM2 physical volumes, Solaris x86 disklabel (vtoc),
Solaris SPARC disklabel.
- Other structures:
- Debian split floppy header, Linux swap.
- Disk images:
- Raw CD image (.bin), Virtual PC hard disk image, Apple UDIF
disk image (limited).
- Boot codes:
- LILO, GRUB, SYSLINUX, ISOLINUX, Linux kernel, FreeBSD
loader, Sega Dreamcast (?).
- Compression formats:
- gzip, compress, bzip2.
- Archive formats:
- tar, cpio, bar, dump/restore.
Compressed files (gzip, compress, bzip2 formats) will also have their contents
analyzed using transparent decompression. The appropriate compression program
must be installed on the system, i.e.
gzip(1) for the gzip
and compress formats,
bzip2(1) for the bzip2 format.
Disk images in general will also have their contents analyzed using the proper
mapping, with the exception of the Apple UDIF format.
See the online documentation at <
http://disktype.sourceforge.net/doc/> for
more details on the supported formats and their quirks.
