Next enter the hex value for the file system type you intend to install on the partition. For Linux swap partitions. The hex value is 82. For Linux ext2 or ext3 partitions, the hex value is 83. For other partition types, use the l command to see a list of file system types and their hex values. Repeat this for each partition you created. As with managing Ext2 and Ext3 drives, create a folder on your Mac to use as a mount point 3. In Terminal, run a command similar to the following to access a folder on the remote system and mount. Feb 18, 2018 Mounting an ext2/ext3/ext4 partition on Mac OS. When trying to mount an ext2/3/4 partition on your Mac, you have at least two options: Option 1: Mount the partition as read-only (RO). With this option, you can only access the files on your partition, you cannot modify them. You can copy your movies, photos etc out of the partition but you.
This tutorial is about partitioning a USB external hard drive as good for internal drive.
Fdisk /dev/sdb To create a new partition (assuming this is a new unused drive), just type “ n “. Then, save your work typing “ w ” and “ q ” to exit the utility. Any doubt or need help about fdisk utility, just type “ m “. The answer depends on you willingness to invest in commercial software: If you don’t mind spending some money on a commercial product, Paragon’s extFS for Mac will give you read and write access to ext2 / ext3 / ext4 file systems. The current version supports all.
First, list devices on your system using one of the following commands :
(USB drive should appear as SCSI drive)
Now, assuming your new drive is “sdb”, use the following command to invoke the fdisk partition utility :

To create a new partition (assuming this is a new unused drive), just type “n“. Then, save your work typing “w” and “q” to exit the utility.
Any doubt or need help about fdisk utility, just type “m“.
Let’s format the partition as traditional EXT3 Linux file system :
Okay, the hard disk partitioning and formatting is done now.
Create a directory where you want to have your drive mounted (replace all “external_hd” value with the name you want to use ) :
Mount the drive :
You’re now ready to use it! However, this mount will not survive to a reboot. To make it permanent, you need to edit fstab :
And add the following line :
NOTE : If you manually mount the drive instead doing the fstab way, do not forget to manually unmount it before unplug it! Serious data loss problem may occur if you skip this step!
Ventoy Disk Layout In MBR
Above is a 32GB USB drive's layout after install Ventoy in it. You can see that the whole disk was divided into 2 partitions in MBR format.
- Why MBR
MBR is the only selection in order to support Legacy BIOS system.
- About Part1
Create Partition For Ext3 Filesystem For Usb Mac Pro
By default, Ventoy select exFAT filesystem for the main partition to hold iso files. exFAT has better compatibility on Windows/Linux/Mac and exFAT is suitable for USB stick.
From Ventoy-1.0.11, you can reformat the 1st partition with other filesystem, exFAT/FAT32/NTFS/UDF/XFS/Ext2/Ext3/Ext4 are supported.
It should be noted that, if you choose XFS/Ext2/Ext3/Ext4, the USB will be unavaliable on Windows and can not be used to install Windows.But if you only use Linux that will be a good choice, because XFS/Ext2/Ext3/Ext4 will have better performance in Linux.

- About Part2
There must be an EFI System Partition with FAT filesystem and that's the mandatory requirements of UEFI specifications.So this partition is created to hold EFI boot file and other files nesscessy to Ventoy. These files are very small, so 32MB is enough. Besides, the EFI partition can be at part1 also, but I set it at part2 just because that in some version of Windows like Windows 7, only the first partition of the USB drive is visable to the system.And that's good for Ventoy's protection.
This partition is very small and used by ventoy, so you better not change anything in this partition.

- About 1MB GAP

This gap is used to hold the bootloader in Legacy BIOS system.
Reserved Disk Space
Since 1.0.14, you can preserve some space at the bottom of the disk. This is a 32GB USB drive's layout after install Ventoy in it (with 2GB reserved space).
When install Ventoy, you can enable and set the reserved space with 'Option' ---> 'Partition Configuration' (Windows) or '-r' option (Linux). The reserved space configuration is only for installation process.
- The reserved space must at the bottom of the disk
- Ventoy MUST use Part1 and Part2, don't change their position and size.
- You can create Part3 and Part4 with the reserved space and use them as you want.
