Website. www.cgsecurity.org /wiki /TestDisk. TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. [ 1 ] TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.
PhotoRec. PhotoRec is a free and open-source utility software for data recovery with text-based user interface using data carving techniques, designed to recover lost files from various digital camera memory, hard disk and CD-ROM. It can recover the files with more than 480 file extensions (about 300 file families). [1]
fsck. fsck in action on a Linux system. The system utility fsck (file system consistency check) is a tool for checking the consistency of a file system in Unix and Unix-like operating systems, such as Linux, macOS, and FreeBSD. [1] The equivalent programs on MS-DOS and Microsoft Windows are CHKDSK, SFC, and SCANDISK.
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
Tux3 – An experimental versioning file system intended as a replacement for ext3. UDF – Packet-based file system for WORM/RW media such as CD-RW and DVD, now supports hard drives and flash memory as well. UFS – Unix File System, used on Solaris and older BSD systems. UFS2 – Unix File System, used on newer BSD systems.
The Filesystem Hierarchy Standard(FHS) is a reference describing the conventions used for the layout of Unix-likesystems. It has been made popular by its use in Linux distributions, but it is used by other Unix-like systems as well.[1] It is maintained by the Linux Foundation.
It was created by Chris Mason in 2007 [15] for use in Linux, and since November 2013, the file system's on-disk format has been declared stable in the Linux kernel. [ 16 ] Btrfs is intended to address the lack of pooling , snapshots , checksums , and integral multi-device spanning in Linux file systems . [ 9 ]
Open Source Tripwire is a free software security and data integrity tool for monitoring and alerting on specific file change(s) on a range of systems [2] [3] originally developed by Eugene H. Spafford and Gene Kim. [4] The project is based on code originally contributed by Tripwire, Inc. in 2000.
