- Getting “No mountable file systems” error message
- Disk image file become inaccessible?
- Want to solve it?
Whenever Mac user try to mount or open DMG file they encounter with an error messages “No mountable file systems”. DMG file is a Mac OS disk image. Due to this error mac users are not able to mount .dmg file of new software and thus cannot be installed. DMG (Disk mounted graphics) files are actually like real disks. This is an image of full content of any storage media like hard drive, CD, DVD etc. it enable secure password protection and file compression function. If you want to access data from DMG files, you have to first mount them.
This is the not one problem. But other one is...In Mac OS X, you can easily create backup of Mac data by creating disk image through DD command (this is a command line tool which create image of entire hard drive volume bit by bit on other storage media. If you want to access data from it, you can mount disk image as hard drive volume and after this you will access data. Finder mount dmg file but however in some cases finder refuses to mount it and give error message---“No mountable file systems’.
This problem may happen if source file corrupted or any other. Roboot may fix this problem. If this is also not able to fix the problem then you can mount these files from the command line –hdiuti. This is the command use to mange disk image. Run this command on command line as root.
$ sudo hdituil attach file name.dmg
(name.dmg is the name of the disk image file).
If this also not work, data will not access.
After, “No mountable file system” error massage, data contained in disk image file become inaccessible. Now in any situation if you need those data, you need mac file recovery process for this.
Cause of this error message is Mac OS is not getting file system in proper format for mounting image. It might be possible that file system is either damage or missing. But now DMG file is unusable for you and data too.
Solution is Run Disk Utility to check the integrity of the file, tool check and if find any error try to fix it. But if this utility also fail to fix the problem then to recover data use third party software. Mac file recovery software with the powerful scanning algorithm performs in-depth scanning and correct the problem to make file accessible. With the user interactive graphical interface, it demands no technical knowledge to use this tool.
Tool supports all latest Mac OSX operating system. It recovers data from HFS, HFS+, HFSX, HFS Wrapper, and FAT file system volumes.
