Recover Data From un-mountable Drive on Mac

Volumes are the logical space in which data, system files, and other information is stored in macOS. While booting a Mac, all the local file systems in a volume are mounted on the operating system.

In other words, a volume is mounted if the macOS is capable of reading and writing data on the disk. Hence mounting is the process in which the Mac operating system gathers information about the corresponding volume in order to gain access to the storage space in order to read and write information.

Unfortunately, under some conditions, a volume or a drive may not get mounted. As a result, the data in that volume becomes inaccessible. In such cases, you will have to recover data from an un-mountable mac drive. Let us first understand the reasons why this happens?

MFT acts as a book-keeper for all the files in the operating systems, it maintains the information about every file on the hard disk.
