Free disk x software for linux

disktypes 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.
The program is written in C and is designed to compile on any modern Unix flavour1. It is self-contained and in general works without special libraries or headers. Some system-dependent features can be used to gather additional information.
As of version 8, disktype knows about the following formats:
File systems:
- FAT12/FAT16/FAT32
- NTFS
- HPFS
- MFS, HFS, HFS Plus
- ISO9660
- UDF
- 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
- 3DO CD-ROM FS
- 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 SPARC disklabel
- Solaris x86 disklabel (vtoc)
Other structures:

xdiskusage is a user-friendly program to show you what is using up all your disk space.

It is based on the design of xdu written by Phillip C. Dykstra.

Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.

The arrow keys may be used to move the selected directory (shown with a red box) around. There is a pop-up menu (use the right mouse button) with other options for changing the display, you can hide nodes, make that node the "root", change the sort order, etc.

Disk Manager project is a simple filesystem configurator that allow you to:
- Automaticly detect new partitions at startup.
- Fully manage configuration of filesystem.
- Enable/disable write support for NTFS (need ntfs-3g installed).

AppleII::Disk is a Perl module for block-level access to Apple II disk image files.

SYNOPSIS

use AppleII::Disk;
my $disk = AppleII::Disk->new(image.dsk);
my $data = $disk->read_block(1); # Read block 1
$disk->write_block(1, $data); # And write it back :-)

AppleII::Disk provides block-level access to the Apple II disk image files used by most Apple II emulators. (For information about Apple II emulators, try the Apple II Emulator Page at http://www.ecnet.net/users/mumbv/pages/apple2.shtml.) For a higher-level interface, use the AppleII::ProDOS module.
AppleII::Disk provides the following methods:

$disk = AppleII::Disk->new($filename, [$mode])

Constructs a new AppleII::Disk object. $filename is the name of the image file. The optional $mode is a string specifying how to open the image. It can consist of the following characters (case sensitive):

r Allow reads (this is actually ignored; you can always read)
w Allow writes
d Disk image is in DOS 3.3 order
p Disk image is in ProDOS order

If you dont specify d or p, then the format is guessed from the filename. .PO and .HDV files are ProDOS order, and anything else is assumed to be DOS 3.3 order.

If you specify w to allow writes, then the image file is created if it doesnt already exist.

$size = $disk->blocks([$newsize])

Gets or sets the size of the disk in blocks. $newsize is the new size of the disk in blocks. If $newsize is omitted, then the size is not changed. Returns the size of the disk image in blocks.

This refers to the logical size of the disk image. Blocks outside the physical size of the disk image read as all zeros. Writing to such a block will expand the image file.

When you create a new image file, you must use blocks to set its size before writing to it.

$contents = $disk->read_block($block)

Reads one block from the disk image. $block is the block number to read.
$contents = $disk->read_blocks(@blocks)

Reads a sequence of blocks from the disk image. @blocks is a reference to an array of block numbers. As a special case, block 0 cannot be read by this method. Instead, it returns a block full of 0 bytes. This is how sparse files are implemented. If you want to read the actual contents of block 0, you must call $disk->read_block(0) directly.

$contents = $disk->read_sector($track, $sector)

Reads one sector from the disk image. $track is the track number, and $sector is the DOS 3.3 logical sector number. This is currently implemented only for DOS 3.3 order images.

$disk->fully_allocate()

Expands the the physical size of the disk image file to match the logical size of the disk image. It will be expanded as a sparse file if the filesystem containing the image file supports sparse files.

$disk->write_block($block, $contents, [$pad])

Writes one block to the disk image. $block is the block number to write. $contents is the data to write. The optional $pad is a character to pad the block with (out to 512 bytes). If $pad is omitted or null, then $contents must be exactly 512 bytes.

$disk->write_blocks(@blocks, $contents, [$pad])

Writes a sequence of blocks to the disk image. @blocks is a reference to an array of block numbers to write. $contents is the data to write. It is broken up into 512 byte chunks and written to the blocks. The optional $pad is a character to pad the data with (out to a multiple of 512 bytes). If $pad is omitted or null, then $contents must be exactly 512 bytes times the number of blocks.

As a special case, block 0 cannot be written by this method. Instead, that block of $contents is just skipped. This is how sparse files are implemented. If you want to write the contents of block 0, you must call $disk->write_block directly.

$disk->write_sector($track, $sector, $contents, [$pad])

Writes one sector to the disk image. $track is the track number, and $sector is the DOS 3.3 logical sector number. $contents is the data to write. The optional $pad is a character to pad the sector with (out to 256 bytes). If $pad is omitted or null, then $contents must be exactly 256 bytes. This is currently implemented only for DOS 3.3 order images.

$padded = AppleII::Disk::pad_block($data, [$pad, [$length]])

Pads $data out to $length bytes with $pad. Returns the padded string; the original is not altered. Dies if $data is longer than $length. The default $pad is " ", and the default $length is 512 bytes.

If $pad is the null string (not undef), just checks to make sure that $data is exactly $length bytes and returns the original string. Dies if $data is not exactly $length bytes.

pad_block is a subroutine, not a method, and is not exported. You probably dont need to call it directly anyway, because the write_XXX methods will call it for you.

ZipSlack is a special edition of Slackware Linux that can be installed onto any FAT (or FAT32) filesystem with about 100 MB of free space. It uses the UMSDOS filesystem and contains most of the programs you will need.

This means that you do not need to repartition your hard disk if you already have DOS or Windows installed. ZipSlack installs into a directory on your DOS filesystem. It can also be installed to and booted from a Zip disk.

This distribution is ideal for people who dont have a lot of hard disk space, do not have a fast Internet connection to download the entire distribution, or who want a Linux distribution they can carry around on a Zip disk.

DOS33 is a collection of utilities that will extract Apple ][ disk images and run pure Applesoft Basic programs. The yacc/bison and lex tools are used to generate the Applesoft Basic parser.

util/catalog - lists and extracts all files in a disk image
aexec/aexec - runs/lists an applesoft basic program
util/asoft_detoken - lists an applesoft basic program
applesoft/asexec - command line interpreter
applesoft/aslist - lists an applesoft basic program
applesoft/eol - "EAMON Online"

Some utilities:

asoft_detoken:
will "detokenize" an applesoft-basic program, and print out the file listing in plain text.

can easily be converted to handle Integer BASIC, but I dont have any such files.

Usage:

asoft_detoken < FILENAME

catalog:

will show contents of a disk image, just like the DOS command "CATALOG"

Usage:

catalog DISK.IMG

This will also create a directory named "DISK" containing all files found on the image

zd:
hex dump utility

mod_dirsize is an Apache module to calculate the disk space used for any virtual host on a server.

The results are displayed in KB using XML.
