Free hard drive data recovery software for linux

Hard Disk Temperature Monitor is my first superkaramba theme, it uses the package hddtemp, please verify if your system has it installed.

I modify this image(http://www.kde-look.org/content/show.php?content=28748)

And made the Icon, from 2 images from the web.

The entire theme is in spanish, but you can translate to any language.

I really apreciate your comments!

Thank you so much, and greetings from Medellin-Colombia!

Parchive project is a tool that helps data recovery of multi-part archives on Usenet.

The original idea behind this project was to provide a tool to apply the data-recovery capability concepts of RAID-like systems to the posting and recovery of multi-part archives on Usenet. We accomplished that goal. Our new goal with version 2.0 of the specification is to improve.

It extends the idea of version 1.0 and takes the recovery process beyond the file-level barrier. This allows for more effective protection with less recovery data, and removes some previous limitations on the number of recoverable parts. See Par1 compared to Par2 for a more detailed view of the differences.

Because this new approach doesnt benefit from like sized files, it drastically extends the potiental applications of PAR. Files such as video, music, and other data can remain in a usable format and still have recovery data associated with them.

The technology is based on a Reed-Solomon Code implementation that allows for recovery of any X real data-blocks for X parity data-blocks present. (Data-blocks referring to files OR much smaller virtual slices of files).

The key to this mission is a clean file format specification which provides all the necessary capabilities for programs to easily verify and regenerate single missing parts out of a set of data-blocks.

Harvs Hamshack Hack is a remaster of the KNOPPIX distro for Amateur Radio Operators (Hams).

This project is directed primarily at Amateur Radio enthusiasts (Hams) who have no prior experience with LINUX. Hopefully, experienced LINUX users (perhaps, even a "guru" or two) will give it a spin and offer corrections and suggestions for improvement ... in fact, they are obligated to do so!

The CD contains a complete LINUX-Knoppix operating system and enough software to accomplish the usual tasks we all perform daily from our homes ... web browsing, email, letter writing, etc.

In addition, there is a huge library of programs for our Amateur Radio hobby.

The Hamshack Hack is a "Live CD". As a "Live CD" system, no installation to your machines hard drive is necessary. The whole package will run off the CD by building a "ram disk" in your machines memory. As soon as you re-boot your machine, the LINUX system vaporizes and youll be back with whatever system is installed on your hard drive.

To obtain your very own copy of the "the Hack", you must download the "hamshack.iso" image file and then, using your favorite CD burner (I use K3B on Linux, or Nero on Windows), burn the image to a CD. Pick the "Burn CD Image" option, else youll end up with just another copy of the .iso file. Then, when the smoke clears, youll boot your machine with this new CD.

KungFu DVD Ripper is a GStreamer based DVD ripper.

KungFu creates backups of your DVDs, saving them as .oggs on your hard drive. It encodes the backup using patent-free codecs, Theora for video and Vorbis for audio.

KungFu is not designed for producing backups that fit within a certain file size (say, for burning onto CD); instead, it is designed to produce backups of consistent quality while maintaining the lowest average file size possible (for building a video library on your hard drive).

GNU ddrescue is a data recovery tool. GNU ddrescue copies data from one file or block device (cdrom, hard disc, etc) to another, trying hard to rescue data in case of read errors.
Ddrescue does not truncate the output file if not asked to. So, every time you run it on the same output file, it tries to fill in the gaps.
The basic operation of ddrescue is fully automatic. That is, you dont have to wait for an error, stop the program, read the log, run it in reverse mode, etc.
If you use the logfile feature of ddrescue, the data is rescued very efficiently (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.
Automatic merging of backups: If you have two or more damaged copies of a file, cdrom, etc, and run ddrescue on all of them, one at a time, with the same output file, you will probably obtain a complete and error-free file.
This is so because the probability of having damaged areas at the same places on different input files is very low. Using the logfile, only the needed blocks are read from the second and successive copies.
The logfile is periodically saved to disc. So in case of a crash you can resume the rescue with little recopying.
Also, the same logfile can be used for multiple commands that copy different areas of the file, and for multiple recovery attempts over different subsets.
Ddrescue aligns its I/O buffer to the sector size so that it can be used to read from raw devices. For efficiency reasons, also aligns it to the memory page size if page size is a multiple of sector size.
Whats New in 1.5 Stable Release:
- The license has been updated to GPL version 3 or later.
Whats New in 1.6-pre2 Development Release:
- Support for sparse writes to the output file has been added.

Cascade Historian software is an event driven data storage program used to maintain persistent time-sequence data sets derived from process data.

Features and Benefits

In addition to providing storage the Historian also offers a historical query facility suitable for generating graphs and tabular output for export to other analysis programs. Other programs can also send data to the Cascade Historian by linking the API library and making the appropriate function calls.

The data storage mechanism within the Cascade Historian will maintain any number of simultaneous time histories, one for each configured process point.

The data for each point is maintained in one or more files, allowing for removal of stale data or offline archival of old data. These files are either numbered in increasing numerical order, or dated. When using dated files, the Cascade Historian automatically begins logging to a new file at midnight.

Data logging by event

The Cascade Historian records data by event. If no data change event occurs for a point, no data is written to disk. This saves disk space when the process point is idle, and captures even very short duration events when the point is changing. This is both more efficient and more accurate than a sampling historian. It is possible to place both a time and value deadband on each point to reduce storage for points whose values are constantly changing by insignificant amounts. The Cascade Historian will not reorder out of sequence data.

Data is stored on disk in fixed length binary records to minimize disk space, with a time resolution of nanoseconds. These files can be easily read by any custom program as well as by the Cascade Historian.

Any process may request data from the Cascade Historian. The Cascade Historian maintains a configurable in-memory cache for each point being recorded so that queries of recent data will not require disk access. If the request cannot be satisfied from the in-memory cache, then the disk files related to the point will be consulted for the data to satisfy the request. The requests can take one of the following forms:

Raw Data - Simply returns all recorded events for the data point, reported vs. time.
Periodic Data - Performs linear interpolation on the data to produce a data set at an even time interval. This produces the same result that a sampling historian would produce.
Relative Interpolation - Performs interpolation of one data point against another to produce a Y vs. X data set. Interpolation is performed on Y to produce (X,Y) pairs at the times of known values of X.
Periodic Relative Interpolation - Performs interpolation of one data point against another to produce a Y vs. X data set. Interpolation is performed on both X and Y to produce (X,Y) pairs at an even time interval.

The Cascade Historian has been built to allow quick addition of other forms of historical query.

Audio Transcriber records large audio samples, like a tape or radio broadcast, to your hard drive and splits it into tracks to be burned onto CD-R media.

The goal of Audio Transcriber is to make it easy to transfer audio tapes, LPs, or radio broadcasts to tracks on CD-R/CD-RW.
