Free disk images software for linux

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).

GRUB Splash Images package contains a collection of splashimages which can be used for GRUB.

If youd like your splashimage in this package send them to mcgrof@ruslug.rutgers.edu.

Quick tips for the impatient:

convert -resize 640x480 -colors 14 image.png image.xpm && gzip image.xpm

Quick tip for debian users: Use "unstable" packages in your /etc/apt/sources.list in order to get the latest GRUB with splashimage support

Quick tip to install GRUB (only Debian users do the apt-get line):

# using the unstable tree
apt-get install grub
grub-install /dev/hda
# Go edit/make a menu.lst file and put it in /boot/grub/menu.lst
grub
# then on the grub prompt run:

# The partition that has the boot partition
root (hd0,0)
install /grub/stage1 (hd0) /grub/stage2 p /grub/menu.lst
quit

ADIOSKIDS is a Fedora-based live and installation CD with support for User Mode Linux (UML) virtual machines, further enhanced by Linux Intrusion Detection System (LIDS) and SELinux (Security Enhanced Linux). The live CD, which includes the KDE desktop environment, uses a compressed loopback filesystem.

The objective of the ADIOS project is to quickly and easily download a consistent operating system environment onto laboratory PCs. The ADIOS environment provides students with administrative privileges required to perform advanced exercises in Network and Systems Administration.

We needed a way to download a pre-installed version of the operating system onto the PC in the laboratory. There are many tools available to do this, but the ADIOS project uses a web server to deliver the Operating System images.

The ADIOS setup image is used to install operating systems onto disk partitions. It also copies the OS images from disk to disk to reduce network traffic. The ADIOS image was ported onto CDROM for students to use at home.

ADIOS-SELinux is a separate boot CD for running NSA Security Enhanced Linux. Additional software is available on the DVD version of ADIOS.

As the name already suggests, ncdu is an NCurses version of the famous old du unix command.

NCurses Disk Usage provides a fast and easy interface to your harddrive. Where is your disk space going? Why is your home directory that large? ncdu can answer those questions for you in just a matter of seconds!

Partition Image application is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file.
The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example); partitions can be saved across the network since version 0.6.0.
Partition Image will only copy data from the used portions of the partition. For speed and efficiency, free blocks are not written to the image file.
This is unlike the dd command, which also copies empty blocks. Partition Image also works for large, very full partitions. For example, a full 1 GB partition can be compressed with gzip down to 400MB.
This is very useful to save partitions to an image in some cases:
- First you can restore your linux partition if there is a problem (virus, file system errors, manipulation error) . When you have a problem, you just have to restore the partition, and after 10 minutes, you have the original partition. You can write the image to a CD-R if you dont want the image to use hard-disk space.
- This utility can be used to install many identical PCs. For example, if you buy 50 PCs, with the same hardware, and you want to install the same linux systems on all 50 PCs, you will save a lot of time. Indeed, you just have to install on the first PC and create an image from it. For the 49 others, you can use the image file and Partition Images restore function.

Mozvert image is a Firefox extension that uses convert from ImageMagick for saving images to its preferred formats.

It adds the entry "Convert Image As..." after "Save Image As..." with 8 predefined formats: PNG, JPG, GIF, XPM, TIFF, BMP, PS (PostScript), XBM, ICO.

Early Macintosh Image LoadEr allows to boot linux-m68k from a floppy on a macintosh such as MacII or Quadra 610.
With it, you can create rescue disk, or remove the MacOS partition (needed by the legacy penguin booter) from your HD.
Create a floppy from rescue disk image
You can find floppy image from the package emile-rescue
Under linux, the command to dump image to floppy is:
# dd if=emile-rescue-x.y.bin of=/dev/fd0 bs=512 conv=sync
then, you can eject floppy with:
# eject /dev/fd0
If you are using MacOS, use MakeDebianFloppy AppleScript (you must use a floppy image with a size of exactly 1474560 bytes).
Enhancements:
- This release has improved SCSI support, allows you to create a bootable CD-ROM, adds Debian packaging, updates the PowerPC part (currently not usable), and introduces apple_driver (currently not usable).

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.
