What is mke2fs in Linux?
DESCRIPTION. mke2fs is used to create an ext2/ext3 filesystem (usually in a disk partition). device is the special file corresponding to the device (e.g /dev/hdXX). blocks-count is the number of blocks on the device. If omitted, mke2fs automagically figures the file system size.
What does mkfs ext4 do in Linux?

Which is better ext3 or Ext4?
Ext4 is functionally very similar to ext3, but brings large filesystem support, improved resistance to fragmentation, higher performance, and improved timestamps.
Why is mkfs used?
mkfs is used to build a Linux filesystem on a device, usually a hard disk partition. The device argument is either the device name (e.g., /dev/hda1, /dev/sdb2), or a regular file that shall contain the filesystem. The size argument is the number of blocks to be used for the filesystem.
Can Windows read Ext4?

Does Ubuntu use Ext4?
ext4 is the default file system for many Linux distributions including Debian and Ubuntu.
Is Ext4 faster than NTFS?
Various benchmarks have concluded that the actual ext4 file system can perform a variety of read-write operations faster than an NTFS partition. Note that while these tests are not indicative of real-world performance, we can extrapolate these results and use this as one reason.
Does mkfs delete data?
mkfs does not explicitly delete files. In the target device it creates structures specific to the desired filesystem, not taking care of anything that is already there. The new filesystem is created empty.
What is mkfs command in Linux?

Does fdisk create filesystem?
To create a filesystem, there are three steps: Create partitions using fdisk or Disk Utility. We learned on Linux that a primary partition is used to boot the Linux system and a swap partition is used to create space to hold extended memory. Format the partitions using mkfs or Disk Utility.
Should I use NTFS or Ext4 for Ubuntu?
If you need to use it cross-platform you should probably go with either NTFS or ExFAT. Native file systems (e.g. XFS, EXT4) have better tools available for Linux, for recovery and maintenance, and probably a more complete implementation. If you use NTFS, you must have Windows or Windows repair disk to make repairs.
