Free hard disk space software for linux

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!

Filesys::DiskSpace is a Perl module as a df replacement.

SYNOPSIS

use Filesys::DiskSpace;
($fs_type, $fs_desc, $used, $avail, $fused, $favail) = df $dir;

This routine displays information on a file system such as its type, the amount of disk space occupied, the total disk space and the number of inodes. It tries syscall(SYS_statfs) and syscall(SYS_statvfs) in several ways. If all fails, it croaks.

OPTIONS

$fs_type

[number] type of the filesystem.

$fs_desc

[string] description of this fs.

$used

[number] size used (in Kb).

$avail

[number] size available (in Kb).

$ffree

[number] free inodes.

$fused

[number] inodes used.

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).

hdimage is a tool for imaging or copying hard disk partitions or entire disks.

hdimage project cleans unused blocks on ext2 partitions and may be used as a backup tool for Linux partitions.

WARNING!

This software has to be tested before use. Do not use it for backups yet.

Some of options arnt implemented, please wait for complete version.

FDMS-3 Ripper is a Perl program for extracting the tracks from the FDMS-3 filesystem. I recently bought a Fostex FD-8 multitrack hard disk recorder for recording music. It works great, but I was disappointed to discover that, although it uses a standard external SCSI hard disk, there was no way to "rip" the recorded tracks from the hard drive to my PC over the SCSI port. The alternatives were to use the analog-out to re-record each track using my soundcard (resulting in loss of quality and loss of synch between tracks), or buying a $500 ADAT card for my PC.

I decided that I would try to figure out a way to rip the music directly over the SCSI port. The FD-8 uses a proprietary Fostex filesystem, FDMS-3. I decided to hook it up to my PC and probed the drive. I was able to figure out the basic layout of the filesystem pretty quickly. Note: this is designed to hard disks formatted in the FDMS-3 "Mastering" mode, which stores the audio data in uncompressed format.

In order to use the program, you will need to take the hard disk that has the FDMS-3 filesystem on it and hook it up to your PC (mine is a SCSI drive -- dont know if this will work with one of the internal IDE drives you can hook up to the FD-8). Make sure that Linux can see the drive (dont try to mount it, though!). You might want to have a look at SCSI-2.4-HOWTO to get the drive recognized. My external hard disk is located at "/dev/sda", but yours could end up elsewhere.

Next, you need to make sure you have the following on your system: perl, sox and fileutils (for the "dd" utility). Security Warning Unfortunately, this program presents significant security issues, so be careful with it. The script needs to be able to access the hard disk directly, so you can either run it as root (not safe), or change the permissons for the hard disk device (in my case, "/dev/sda"). Run the program with "./fdms3rip /dev/sda" (substituting the actual location of your hard disk).

This will list all of the programs present on the hard disk. Then, run it again with the number of the program you want to fetch off the hard disk: "./fdms3rip /dev/sda 5" to get all of the recorded tracks for program number 5. After waiting a bit, you should now have a bunch of WAV files on your Linux machine. Warning This program will create and erase files with the names "dir" and "header" in the directory it is run from. It would be best to run this program from a clean directory, just to make sure there are no problems.

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.

DiskMonitor is a Kicker Applet of KDE that monitors free space of some disks.
Points:
Providing a fabulous and compact view of presentation like LCD.
Drawing itselt with very low-flicker.
Notes:
It supports a horizontal panel of KIcker, but doesnt work in a vertical panel.
It was tested in KDE 3.5.4 on FC5
Enhancements:
- Enable to sort partitions by Mount-Point.
- Support USB Memory Stick
- Change range of "refresh interval time" to 5sec - 60sec.(default 5sec)

Dariks Boot and Nuke is short DBAN is a self-contained boot floppy that securely wipes the hard disks of most computers.
DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.
Main features:
- Free.
- Fast. Rapid deployment in emergency situations.
- Easy. Start the computer with DBAN and press the ENTER key.
- Safe. Irrecoverable data destruction. Prevents most forensic data recovery techniques.
Enhancements:
- SysLinux 2.13
- Linux 2.4.33
- LZMA 4.32
- uClibc 0.9.20
- Busybox 0.60.5
- Ncurses 5.3
- WinImage 8.0.8000
- dban-1.0.7 was compiled with Debian gcc-3.3 1:3.3.5-13
- This release is compressed with LZMA, which provides much more free space on the floppy disk. LSI MPT and I2O drivers were added.
- Thanks go to Igor Sobrado for reporting the "5220.22-M" typo.
- Thanks go to Dorina Lanza for reporting a block adjustment error.
