Free disk doctors linux data recovery software software for linux

Poisson Media Recovery project can be used to retrieve slightly damaged files from CD-ROM media.

It sequentially mounts and umounts the device, and on each mount it tries to read as many new 512 byte sectors as possible.

I was able to use this tool to save some files from old CDs.

Kaboot Linux Operating system aims to provide an operating system which you can take anywhere and has all your favourite programs on.
Kaboot operating system is avaliable as a Live CD or Live USB you can take with you anywhere.
A number of different versions are avaliable, two optimised for size or speed, one for functionality, and one science based.
All containing a host of useful programs able to boot virtually any computer (meeting the minimum requirements) from CD and
USB.Kaboot is still in active development and if you find a bug or fix, you can let me know in the forums.
Enhancements:
- A network bug was fixed.
- A few debugging utilities were added.
- Hotplugging was implemented.

Dyne:bolic GNU/Linux is a live bootable distribution, an operating system which can also be installed just by copying a directory onto the hard disk.
Dyne:bolic GNU/Linux is user-friendly, recognizes your hardware devices (sound, video, firewire, and USB), and offers a vast range of software for multimedia production: editing and streaming of audio and video, 3D modeling, photos, peer-to-peer filesharing, Web browsing and publishing, word processing, email, encryption, and networking.
Enhancements:
- The pure:dyne low latency GNU/Linux distribution for media artists comes with optimized and tested software such as supercollider, icecast, csound, packet forth, fluxus, and much more, including pure data and a collection of essential externals and abstractions (PDP, PiDiP, Gem, GridFlow, RRadical, and PixelTango).
- It is compatible with dyne:II, so all the Home Studio "classics" can be used (Ardour, LADSPA, seq24, Rezound etc.).
- Numerous essential graphics programs are also bundled (such as Inkscape, GIMP, and Blender).

Linux Mobile System project (LMS) is a full Linux system whose support is the new USB Flash Memory Drives. The intention is to boot any PC with USB support with our system and therefore we will have every administration and analysis applications that we have selected, so we will not need install it. This way, always we will be able to get our Linux system ready to use in our pocket.
This project arose with the intention to study the Linux system of exhaustive way and simultaneously enjoy with it. The initial idea is to fuse two separated disciplines: the programming and the systems management. So well center our study in the denominated "system programming, as much networking level as at device level (drivers).
Main features:
- To initiate our Linux system from memories flash USB.
- The system will be a selection of common GNU tools in every system: disk diagnosis, memory, hardware, networks monitoring tools, etc.
- LMS Tux
- As far as possible well develop new tools and/or utilities with the objective to study deeply the underlying technology.
- The programming languages used will be C, C++, Python and Perl, without forget the system shell scripts.
- The resources minimization (disk space, memory...) isnt a functional objective of the developments.
LMSs main aim is to achieve a highly specialized distribution of GNU/Linux which can carried through the USB Flash Memory Drives. Once the distribution is ready in the USB device, it can be carried in your own pocket and you can start up any PC x86 with no need to install it directly in the PC.
The LMS system is aimed at the development of specific tasks such as network administration, security analysis of networks, and recovery and repair of host data, as well as all information exchange, which is what makes it different from other portable systems such as "live CDs". The main idea is to carry all the potency of Linux and our tools in our own pockets, ready to be used.

The gzip Recovery Toolkit attempts to automate the recovery of data from corrupted gzip files (including tarballs) through a program called gzrecover. gzip Recovery Toolkit package is still very experimental at this point.
99% of "corrupted" gzip archives are caused by transferring the file via FTP in ASCII mode instead of binary mode. Please re-transfer the file in the correct mode first before attempting to recover from a file you believe is corrupted.
This program is provided AS IS with absolutely NO WARRANTY. It is not guaranteed to recover anything from your file, nor is what it does recover guaranteed to be good data. The bigger your file, the more likely that something will be extracted from it. Also keep in mind that this program gets faked out and is likely to "recover" some bad data. Everything should be manually verified.
Usage:
Run gzrecover on a corrupted .gz file. Anything that can be read from the file will be written to a file with the same name, but with a .recovered appended (any .gz is stripped). You can override this with the -o option.
To get a verbose readout of exactly where gzrecover is finding bad bytes, use the -v option to enable verbose mode. This will probably overflow your screen with text so best to redirect output to a file.
Once gzrecover has finished, you will need to manually verify any data recovered as it is quite likely that our output file is corrupt and has some garbage data in it. If your archive is a tarball, read on.
For tarballs, the tar program will choke because GNU tar cannot handle errors in the file format. Fortunately, GNU cpio (tested at version 2.5 or higher) handles corrupted files out of the box.
Heres an example:
$ ls *.gz
my-corrupted-backup.tar.gz
$ gzrecover my-corrupted-backup.tar.gz
$ ls *.recovered
my-corrupted-backup.tar.recovered
$ cpio -F my-corrupted-backup.tar.recovered -i -v
If you have a previous release, please note that the patches to GNU tar have been discontinued. They were only marginally successful at best and GNU cpio does what is needed out of the box and does it far better.
Enhancements:
- Documentation updates, including a man page, plus code cleanup to better enable inclusion in GNU/Linux packages and eliminate compilation warnings.
