Sector size (logical/physical): 512B/4096 I am using my 16GB pen-drive and I will make it as a drive in my system. First list the partition by using fdisk -l or parted -l commands to identify the hard drive you want to partition.I assumed that you have added a new hard drive or pen drive to your Linux machine, in which you will create the new ext4 partition, and.For example, if you add a new disk drive to the system, you may want to partition the drive, and use the ext4 file system. It was designed as a progressive revision of the ext3 file system and overcomes a number of limitations in ext3.Īfter installation, it is sometimes necessary to create a new file system. The ext4 file system is a scalable extension of the ext3 file system. This process was tested with Ubuntu 14.04, but should work with most Linux distros.The ext4 or fourth extended filesystem is a widely-used journaling file system for Linux. All finished! cd into /media/usb and browse the contents of the drive.Mount the drive: $ sudo mount /dev/sdb2 /media/usb.Make a directory into which you'll mount the drive: $ mkdir /media/usb.List all visible drives on the system: $ sudo fdisk -l, and it should be one of /dev/sdb1 or /dev/sdb2 (usually, whichever is larger, with 'System' of 'Linux'.

Click on the USB icon in VirtualBox's window, and select the flash drive to 'capture' it inside the VM.

Plug in the flash drive once the VM is booted.

Boot a new linux VM (any kind will do, as long as it's modern enough to support ext4), shut it down, go into Settings for the VM inside VirtualBox and enable USB, then reboot.įollow these steps once the VM is booted, to mount the flash drive: To mount an ext4-formatted SD or microSD card on a Mac, the easiest option is to use VirtualBox (and, in my case, Vagrant with one of Midwestern Mac's Ubuntu boxes).

Since I'm running a Mac, and don't have a spare linux-running machine that can mount ext4-formatted partitions (like those used by default for official Raspberry Pi distributions like Raspbian on SD cards), I don't have a simple way to mount the boot partition on my Mac to tweak files on the Pi this is a necessity if, for example, you break some critical configuration and the Pi no longer boots cleanly.
