In computer operating systems, mkfs is a command used to format a block storage device with a specific file system. The command is part of Unix and Unix-like operating systems . In Unix, a block storage device must be formatted with a file system before it can be mounted and accessed through the operating system's filesystem hierarchy .
fsck time/Inode Count(ext3 vs. ext4) With ext4 the e2fsck runtime should come down considerably, as can be seen from the graph. As the userspace companion for the ext2, ext3, and ext4 drivers in the Linux kernel, the e2fsprogs are most commonly used with Linux. However, they have been ported to other systems, such as FreeBSD and Darwin.
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

High-level formatting of disks on these systems is traditionally done using the mkfs command. On Linux (and potentially other systems as well) mkfs is typically a wrapper around filesystem-specific commands which have the name mkfs.fsname, where fsname is the name of the filesystem with which to format the disk.

Btrfs – Extent-based copy-on-write (COW) file system for Linux; EFS – Extent File System – SGI's first-generation file system for IRIX; ext4 – Linux file system (when the configuration enables extents – the default in Linux since version 2.6.23) Files-11 – OpenVMS file system
badblocks is a Linux utility to check for bad sectors on a disk drive.It can create a text file with list of these sectors that can be used with other programs, like mkfs, so that they are not used in the future and thus do not cause corruption of data.
For example, 72% of survey respondents with grandchildren say they hardly ever feel isolated compared with 62% of those without grandchildren. Why younger families aren’t having kids.
The uses of extended attributes in Be-like systems are varied: For example, Tracker and OpenTracker, the file-managers of BeOS and Haiku respectively, both store the locations of file icons in attributes, [8] Haiku's "Mail" service stores all message content and metadata in extended file attributes, [9] and the MIME types of files are stored in ...
