Disk Utility User Guide
Disk Utility on Mac supports several file system formats:
Apple File System (APFS): The file system used by macOS 10.13 or later.
Mac OS Extended: The file system used by macOS 10.12 or earlier.
MS-DOS (FAT) and ExFAT: File systems that are compatible with Windows.
Jul 12, 2010 Your final task is to create an ext4 filesystem on your new partition, /ev/sdc1. With the -L option of mkfs, label the partition and also show the GUID using the blkid command as you did for the ext3 partition above. Illustrates this. Ext2 file system can be easily converted to ext3 file system. It only needs two simple orders to complete the conversion. The users need no time to back up, recover, and format the partition. Use the small tool tune2fs provided by ext3file system, it can easily convert ext2 file system to ext3 journal file system.
Apple File System (APFS)
Apple File System (APFS), the default file system for Mac computers using macOS 10.13 or later, features strong encryption, space sharing, snapshots, fast directory sizing, and improved file system fundamentals. While APFS is optimized for the Flash/SSD storage used in recent Mac computers, it can also be used with older systems with traditional hard disk drives (HDD) and external, direct-attached storage. macOS 10.13 or later supports APFS for both bootable and data volumes.
APFS allocates disk space within a container (partition) on demand. When a single APFS container has multiple volumes, the container’s free space is shared and is automatically allocated to any of the individual volumes as needed. If desired, you can specify reserve and quota sizes for each volume. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all the volumes in the container.
Choose one of the following APFS formats for Mac computers using macOS 10.13 or later.
APFS: Uses the APFS format. Choose this option if you don’t need an encrypted or case-sensitive format.
APFS (Encrypted): Uses the APFS format and encrypts the volume.
APFS (Case-sensitive): Uses the APFS format and is case-sensitive to file and folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.
APFS (Case-sensitive, Encrypted): Uses the APFS format, is case-sensitive to file and folder names, and encrypts the volume. For example, folders named “Homework” and “HOMEWORK” are two different folders.
Winclone 4 free download windows 7. You can easily add or delete volumes in APFS containers. Each volume within an APFS container can have its own APFS format—APFS, APFS (Encrypted), APFS (Case-sensitive), or APFS (Case-sensitive, Encrypted).
Mac OS Extended
Choose one of the following Mac OS Extended file system formats for compatibility with Mac computers using macOS 10.12 or earlier.
Mac OS Extended (Journaled): Uses the Mac format (Journaled HFS Plus) to protect the integrity of the hierarchical file system. Choose this option if you don’t need an encrypted or case-sensitive format.
Mac OS Extended (Journaled, Encrypted): Uses the Mac format, requires a password, and encrypts the partition.
Mac OS Extended (Case-sensitive, Journaled): Uses the Mac format and is case-sensitive to folder names. For example, folders named “Homework” and “HOMEWORK” are two different folders.
Mac OS Extended (Case-sensitive, Journaled, Encrypted): Uses the Mac format, is case-sensitive to folder names, requires a password, and encrypts the partition.

Windows-compatible formats
Windows Ext3 Filesystem
Choose one of the following Windows-compatible file system formats if you are formatting a disk to use with Windows.
MS-DOS (FAT): Use for Windows volumes that are 32 GB or less.
ExFAT: Use for Windows volumes that are over 32 GB.

How To: create filesystem with mkfs
The mkfs command available in UNIX and Linux operating systems is used to create file systems on various storage devices or partitions. It stands for “make filesystem”, and creating a file system is essentially an equivalent to what is popularly known as “formatting” a disk or a partition with a particular file system type (such as FAT32 or NTFS in Windows).
In other words you can use the mkfs command to format a storage device or a partition to a particular file system type, which can be ext2, ext3, ext4, FAT, NTFS, HFS, and others.
Basic usage of mkfs
This is its basic usage:
Where type should be replaced by the file system type such as ext3, and /dev/device by a device you want to format such as /dev/sdb1. The sudo command before mkfs just makes it run as a superuser or root, which is typically necessary when making file systems.
Here’s an example command:
This would format the device at /dev/sdb1 with an ext3 file system. Note that this will for sure delete all data you might have on that device!
Getting list of disks and paritions
If you’re not sure what device node (like /dev/sdb1) your partition or storage device is on you can run the sudo fdisk -l command to get a list that can help you determine which it is. If it is an USB stick or other external USB storage, for example, it will reside under a different letter than your internal disks.
So if your internal disk is /dev/sda (likely), and you don’t have two or more disks in your machine, then your external storage device will likely be at /dev/sdb. If you do have multiple storage devices built into your computer then they may be at /dev/sda and /dev/sdb respectively which would put any external device you connect at /dev/sdc. As for numbers, they simply represent the partition. So /dev/sdb1 is simply the first (even if only), partition on that device.
Moving back to making file sytems, you can also use shortcut commands that may be available for various file systems suck as mkfs.ext4 for ext4, mkfs.vfat for FAT, and so on. Then running a command like this.
. will have the same result as the previous example command, and will create an ext4 file system on /dev/sdb1, which in this example happens to be an USB flash drive.
Finally, if you receive a message telling you that the device is mounted and it will not make a file system on it you will need to unmount it using the umount command like this:
And then you can proceed with formatting as shown above.
