The SB is located at the beginning of the partition. There are two copies to avoid file-system corruption. It contains basic partition information and some default F2FS parameters. Checkpoint (CP) The CP contains file system information, bitmaps for valid NAT/SIT sets, orphan inode lists, and summary entries of current active segments.
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.

For compatibility with other operating systems using a FAT partition, OS/2 attributes are stored inside a single file "EA DATA. SF" located in the root directory. This file is normally inaccessible when an operating system supporting extended attributes manages the disk, but can be freely manipulated under, for example, DOS.

GParted is not capable of cloning an entire disk, but only one partition at a time. The file system being cloned should not be mounted. GParted clones partitions at the filesystem-level, and as a result is capable of cloning different target-size partitions for the same source, as long as the size of the source filesystem does not exceed the ...
The extended file system, or ext, was implemented in April 1992 as the first file system created specifically for the Linux kernel. Although ext is not a specific file system name, it has been succeeded by ext2, ext3, and ext4.
The only filesystem that directly supports UBI is UBIFS, but using gluebi it's possible to emulate a MTD device, which can then be used to run other flash filesystems like JFFS2 and YAFFS, and using ubiblk it's possible to emulate block devices, which can run common filesystems like Ext4.
