Complete Informatin How to Recover Data from Lost Partitions on MacOS

Losing files on your Mac, whether by accident or due to hardware failure, can put you in trouble. At some point, you must experience such a situation. When receiving a hard disk, you have to divide it into several partitions for better data management and maximize the usage of space. Also, storing data in separate partitions can prevent instances like data loss. 

However, losing essential data from these partitions can be a terrifying experience, especially if you have never experienced this before. In this article, we have provided the best Mac data recovery methods to recover data from lost partition on Mac OS

Different Types of Mac Partitions

Both Windows and macOS use partitions to segment your hard drive into smaller portions. It gives you more control over where your data is stored and organized. Effectively, there are several types of partitions for Mac devices. This includes:

Apple File System (APFS): By default, all Macs with macOS 10.13 or later use this partition type. This file system is optimized for solid-state storage devices and it offers robust encryption, snapshots, and many other useful features. There are sub-types of this file system, i.e., plain APFS, encrypted APFS, case-sensitive APFS, and encrypted and case-sensitive APFS.

Mac OS Extended (HFS+): Prior to APFS, this file system was the default file system in all Mac devices with macOS 10.12 and earlier. While it was used as a partition type, it lacks several important features that modern file systems must have, such as encryption.

MS-DOS (FAT) and exFAT: These two file systems were developed by Microsoft, and were used in macOS devices as they provide compatibility with external storage devices. Both partition types are best for those who work with dual operating systems or external storage devices.

What Causes Partition Loss on Your Mac Device?

There are several reasons why data from partitions may be lost or deleted. Some of these are:

Corrupted Partition Table

Once the partitioning of the disk is completed, a partition table is created. This table helps the operating system recognize the disk. If the Master Boot Record (MBR) or partition table gets corrupted or lost, the partition will be lost. After that, it will not be possible to write and read data from it.

Malware or Virus Issues 

There might be some virus or malware attacks on your device that can corrupt disk drives. If your drive gets affected by such a threat, your personal data and files will get removed without any warning.

Improper Work with Disk Utilities 

The sudden deletion of any partition can cause the failure of the others. This makes the logical volumes of the entire drive inaccessible. While expanding or merging multiple partitions, if electricity (power) was lost, or the operating system hung, the entire hard disk became inaccessible.

Sudden System Shutdown or Power Loss

Instances may occur when the power failure or emergency power failure can happen while writing information, partitioning, or formatting the drive. In such cases, the hard drive may start displaying errors. After correcting them, it is possible to record only one part of the information. Therefore you may face problems while reading and normally using such files.
