The journalling code included in this driver means you do not have to run e2fsck (file system checker) on your file systems after a crash. The journal keeps track of any changes that were being made at the time the system crashed, and can ensure that your file system is consistent without the need for a lengthy check. Other than adding the journal to the file system, the on-disk format of ext3 is identical to ext2. It is possible to freely switch between using the ext3 driver and the ext2 driver, as long as the file system has been cleanly unmounted, or e2fsck is run on the file system. To add a journal on an existing ext2 file system or change the behavior of ext3 file systems, you can use the tune2fs utility ("man tune2fs"). To modify attributes of files and directories on ext3 file systems, use chattr ("man chattr"). You need to be using e2fsprogs version 1.20 or later in order to create ext3 journals (available at ). config ADK_KERNEL_EXT4_FS prompt "EXT4 filesystem support" tristate select ADK_KERNEL_JBD2 default n help Ext4 filesystem. config ADK_KERNEL_HFSPLUS_FS prompt "HFS+ filesystem support" tristate select ADK_KERNEL_NLS_UTF8 select ADK_KERNEL_MISC_FILESYSTEMS default n help If you say Y here, you will be able to mount extended format Macintosh-formatted hard drive partitions with full read-write access. This file system is often called HFS+ and was introduced with MacOS 8. It includes all Mac specific filesystem data such as data forks and creator codes, but it also has several UNIX style features such as file ownership and permissions. config ADK_KERNEL_NTFS_FS prompt "NTFS file system support" tristate default n help NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003. Saying Y or M here enables read support. There is partial, but safe, write support available. For write support you must also say Y to "NTFS write support" below. There are also a number of user-space tools available, called ntfsprogs. These include ntfsundelete and ntfsresize, that work without NTFS support enabled in the kernel. This is a rewrite from scratch of Linux NTFS support and replaced the old NTFS code starting with Linux 2.5.11. A backport to the Linux 2.4 kernel series is separately available as a patch from the project web site. For more information see and . If you are not using Windows NT, 2000, XP or 2003 in addition to Linux on your computer it is safe to say N.

It is completely multi-threaded, can support large files and large filesystems, extended attributes, variable block sizes, is extent based, and makes extensive use of Btrees (directories, extents, free space) to aid both performance and scalability.
