A disk or drive with a RAW file system is also known as RAW disk or RAW drive. When a hard drive or external storage device is shown as RAW, it could be: The file system of the drive is missing or damaged; The RAW drive has not been formatted with a file system; The current file system of the storage medium is not recognized by the computer
A flash file system is a file system designed for storing files on flash memory–based storage devices. While flash file systems are closely related to file systems in general, they are optimized for the nature and characteristics of flash memory (such as to avoid write amplification ), and for use in particular operating systems .
HFSExplorer is a Java application for viewing and extracting files from an HFS+ volume (Mac OS Extended) or an HFSX volume (Mac OS Extended, Case-sensitive). The volume can be located either on a physical disk, in various Apple disk image and sparse disk image formats, or a raw file system dump. However, HFSExplorer is a read-only solution; it ...
That SFF standard described a communication protocol for an ATA host to use and control monitoring and analysis in a hard disk drive, but did not specify any particular metrics or analysis methods. Later, "S.M.A.R.T." came to be understood (though without any formal specification) to refer to a variety of specific metrics and methods and to ...
Journalling Flash File System version 2 or JFFS2 is a log-structured file system for use with flash memory devices. [1] It is the successor to JFFS . JFFS2 has been included into the Linux kernel since September 23, 2001, when it was merged into the Linux kernel mainline as part of the kernel version 2.4.10 release.
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.

Other flash file systems, such as YAFFS2, never make use of this "rewrite" capability – they do a lot of extra work to meet a "write once rule". Although data structures in flash memory cannot be updated in completely general ways, this allows members to be "removed" by marking them as invalid.
