Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button and set the ZeroData option to one-pass. Click on the Erase tab in the DU main window. After DU loads select your startup volume (usually Macintosh HD) from the left side list. To unmount a disk image in Windows, open "My Computer," select the disk image, and click "Eject this disk." In Mac OS X, select the disk image on the desktop and drag the disk image to the trash, which will change to an Eject icon. Select Disk Utility from the main menu and click on the Continue button. Disk images can also be unmounted, which may free up some RAM used by the system to mount the image. External storage devices should typically be unmounted before being disconnected to avoid corrupting files. It takes a mounted disk and makes it inaccessible by the computer. Unmounting a disk is, not surprisingly, the opposite of mounting a disk. However, unlike a physical disk, most disk images are read-only, meaning new data cannot be written to the disk. Once the disk image has been mounted, its contents will appear as a physical disk in the computer. Disk images may be mounted by either the operating system or a disk utility program, such as Nero for Windows or Apple Disk Utility for the Mac. While disk images are not physical disks, they must also be mounted in order for the computer to recognize them. Most disks are automatically mounted by the operating system when they are connected. This is a software process that enables the operating system to read and write data to the disk. You must create your mount point in advance.Answer: Mounting a hard disk makes it accessible by the computer. /media/dave/NAS: The name of the mount point.The root of the share is a directory called Backup, but its Samba share name is set to share. //192.168.4.13/share: The network location of the device with the Samba share on it, and the Samba name of the shared directory.-o credentials=/etc/samba/creds,uid=1000,gid=1000: The options parameters are the path to a file called creds that is secured and contains the user name and password for the Raspberry Pi user the User ID (UID) and Group ID (GID) that are used to set the owner and group of the root of the file system.Let’s break down the parts of that command. When the installation has completed, mount the share with a command like the following, changing the IP address, share name and mount point (which must already exist) to suit your circumstances. On other Linux distributions, use your Linux distribution’s package management tool instead. Use apt-get to install this package onto your system if you’re using Ubuntu or another Debian-based distribution. They type exit to disconnect from the Raspberry Pi and the prompt changes back to use Samba, you must install the cifs-utils package. The contents are two directories, one called dave and one called pat. So now we know what to expect when we mount the Samba share. They list the contents of the shared directory at /media/pi/USB64/Backup. The df command can also be used to display which file systems are mounted and where their mount points are. RELATED: Which Linux File System Should You Use? Interrogate Your File System With df errors=remount -o: If a sufficiently serious error is detected, the file system will be remounted in read-only mode to allow diagnosis.relatime: The kernel is using an optimized scheme to record file access and modification meta-data.rw: The file system is readable and writable.On this test computer, there is a single ext4 file system, it is on device sda-the first storage device mounted, usually the main hard drive-and mounted on /, which is the root of the file system tree. We’ve also issued a command to list ext4 file systems. You’ll want to substitute the tmpfs parameter for the file type in which you are interested. A tmpfs file system appears as though it were a regular, mounted file system but it is actually stored in volatile memory-the tmp stands for temporary-instead of on a persistent storage device.
