Solutions to Failed to Format Ext4 Windows

If you are trying to format Ext4 Windows and you have not found any way to do it successfully, then you’d better read this article since it provides you a perfect assistant to help you format disk to Ext4 Windows.

You should choose the appropriate file system format for your storage device so that the particular operating system can recognize it. However, making the right choice sometimes might be difficult since there are various types of file systems.

For Windows, NTFS is the most used file system, also the default one. Windows also supports REFS, exFAT, and FAT32. Microsoft is removing support for REFS from Windows 10 Pro.

For Mac, the default file system is APFS, and it supports a handful of common file systems - HFS+, FAT32, and exFAT, with read-only support for NTFS.

Well, Linux supports lots of file systems, while the common choices are Ext family, XFS, JFS, and btrfs, and its default option is Ext4.

If you plan to switch from Windows to Linux, you may need to format your internal hard drives or external devises (like SD card drives) to Ext4 on the Windows operating system so that Linux can successfully identify them. Or, if you are dual booting Windows and Linux, you may want to access files on your Windows system from Linux at some point, which also requires formatting the disk as Ext4.

Apart from the reasons I put there, you might have various reasons according to your own specific situation. Well, no matter what, the need is to format Ext4 Windows.

Ext4, Ext3, and Ext2

If you are new to the Linux system, you may not know much about Ext file system. In this part, we’ll talk about file systems Ext2, Ext3, and Ext4, which belong to the Linux operating system.

Ext2: Second Extended File System

Ext2 stands for second extended file system which was first introduced by Remy Card in 1993. It does not support journaling feature; therefore, it is recommended to be used on flash drives like SD card or USB which do not need the overhead of journaling.

The maximum individual file size of Ext2 can be 2 TB and overall ext2 file system size can be 32 TB.

Ext3: Third Extended File System

Ext3 is short for third extended file system. It was developed by Stephen Tweedie and was introduced in 2001. It was available since Linux Kernel 2.4.15.

The main benefit of Ext3 is that it supports journaling feature. The journaling feature has a dedicated area in the file system that keeps track of all changes. When the system crashes, the file system is less likely to be corrupted due to the journaling.

The maximum single file size can be 2 TB, and the total Ext3 file system size can be up to 32 TB. You can convert an Ext2 file system to Ext…without data loss.

Ext4: Fourth Extended File System

Ext4 stands for fourth extended file system which was introduced in 2008, starting from Linux Kernel 2.6.19.

Ext4 supports huge single file size and overall file system size. The maximum individual file size can reach to 16 TB. The overall maximum Ext4 file system size is 1 EB (exabyte). Ext4 also supports journaling, and you can choose to turn the journaling feature “off”.
