smartmontools contains utilities that control and monitor storage devices using the Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) system built into ATA and SCSI hard drives. This is used to check the reliability of the hard drive ... [More] and to predict drive failures. It is meant to be an up-to-date replacement for the ucsc-smartsuite and smartsuite packages, and is derived from that code. [Less]

GNU Parted is an industrial-strength package for creating, destroying, resizing, checking and copying partitions, and the file systems on them. This is useful for creating space for new operating systems, reorganising disk usage, copying data on hard disks and disk imaging.

WinDirStat is a disk usage statistics viewer and cleanup tool for MS Windows (all current variants). It shows disk, file and directory sizes in a treelist as well as graphically in a treemap, much like KDirStat and SequoiaView.

The Logical Volume Manager (LVM) is a subsystem for online disk storage management which has become a de facto standard for storage management under Linux.

Centreon is a network, system, applicative supervision and monitoring tool, it is based upon the most effective Open Source monitoring engine : Nagios. Centreon provides a new frontend and new functionnalities to Nagios. It allows you to be more ... [More] efficient in your network monitoring, but also allows you to make your supervision information readable by a largest range of users. Indeed, a non technical user can now use the Centreon/Nagios couple to easily understand your network infrastructure thanks to charts and graphical representations of the gathered information. Skilled users still have access to specific and technical information collected by Nagios though. [Less]

The Enterprise Volume Management System (EVMS) Project has the goal of providing unparalleled flexibility and extensibility in managing storage. It represents a new approach to logical volume management, as the architecture introduces a plug-in model that allows for easy expansion or customization of various levels of volume management.

GrandPerspective is a small utility application for Mac OS X that graphically shows the disk usage within a file system. It can help you to manage your disk, as you can easily spot which files and folders take up the most space. It uses a so called ... [More] tree map for visualisation. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary. [Less]

The Linbox Rescue Server (LRS) is a tool to centralize hard disk images (like Ghost Enterprise Server), file backups, hardware and software inventory (with Windows, Linux, and Mac OS X agents), and remote access on a single server. It can be managed ... [More] from any PC through a Web-based administration interface, and disk images can be restored using PXE boot or using a bootable CD or DVD. It supports Ext2/3, ReiserFS, XFS, JFS, and LVM v1/v2. [Less]

The userspace portion of device mapper, a generic framework to map one block device into another with sector granularity. Device mapper forms the foundation of LVM2 and EVMS, software RAIDs, dm-crypt disk encryption, and offers additional features such as file-system snapshots.

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

Magic Rescue scans a block device for file types it knows how to recover and calls an external program to extract them. It looks at "magic bytes" in file contents, so it can be used both as an undelete utility and for recovering a corrupted drive or partition. As long as the file data is there, it will find it.

TestDisk is a powerful free data recovery program! It was primarily designed to recover lost partitions, repair FAT/NTFS boot sector, NTFS MFT and Ext2/Ext3 superblock and/or make non-booting disks bootable again when these symptoms are caused by ... [More] faulty software, certain types of viruses or human error (such as accidentally deleting your Partition Table). PhotoRec is a File Recovery program designed to recover lost files; including video, documents and archives from Hard Disks, CDRom and lost pictures from digital camera memory (thus, its Photo Recovery name). PhotoRec ignores the filesystem and goes after the underlying data, so it can still find files even if your media's filesystem has been severely damaged or re-formatted (overwritten data, of course, can not be recovered). [Less]

GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors. The basic operation of ddrescue is fully automatic. That is, you don't have ... [More] 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. [Less]

Ruby StashPermanently save your Ruby objectsOverviewSerializes your ruby objects and writes them as files to disk. Easily load stashed object. Gzips all files for you to save space (can be turned off). InstallationRubyforge project. gem ...
