【Page Break】 Part 1: An All-Around Guide to Partitioning Your Mac

The design of Mac partitions or volumes is similar to that of Windows, serving as a database for users to store and maintain data on their computers. Due to common issues like hard drive failure, unexpected system shutdowns, virus attacks, power surges, software corruption, file system corruption, or other errors, Mac computers can encounter problems akin to those on Windows machines – losing, deleting, formatting, or having abnormal partitions.

It's important to understand the different volume types, because you can choose the format you need when partitioning your Mac's hard drive. There are three main types of volumes for a Mac:

• APFS (Apple File System). This is the default file system for Macs and is best for devices running macOS High Sierra 10.13 or later. It offers faster performance, stronger encryption, and better handling of data than HFS+. It's a great choice for SSDs and newer Macs using recent versions of macOS.
• HFS+ (Hierarchical File System Plus). This was the file system before APFS. Older versions of macOS (macOS 10.12 or earlier) use this file system. You can still use it if you need to. If you have an older Mac that doesn't support APFS and a newer one, this is a good choice for compatibility or for use with the older Mac. However, otherwise, APFS is recommended because it has many useful features.
• MS-DOS (FAT) and exFAT. These file systems were created by Microsoft but are supported by macOS to allow compatibility with external storage devices formatted with a Windows file system.

Solution: Recover Deleted Partition on Mac

When you manage your hard drive through Terminal, you might accidentally delete a partition on your Mac. This confuses macOS and keeps you from accessing your files because it can't tell where one section of the drive ends and another begins. Usually, the actual partitions are still working fine, but the partition map is damaged or corrupt.

In most cases, the deleted partition along with all its data can be restored. If the partition can't be fully recovered, it's still worth retrieving the most important files. This is possible with both free and paid partition recovery software for Mac.
