How To Recover Deleted Partitions On Mac?

To recover a deleted partition on Mac, follow the following steps,

  1. Go to Application>Utilities>Disk Utility. Select the drive which contains the lost partition from the left panel and go to Info tab
  2. If you somehow know the exact name of the file system, then select “Mac OS Extended ” under the File System column as it is compatible with both Linux and Windows. Or if you don’t know the name, leave everything as it is and proceed further. 
  3. Click on the Restore button below the “Where” section. Enter a new volume name or leave as it is by specifying a volume number. Hit OK and you will see the deleted partition is back.

The above step can be used to recover or restore deleted partitions on Mac. As it only overwrites the data with a new one, the chances of losing data are less, and the drive’s performance is not compromised as well.

Limitations Of This Method

This method won’t work if there is no free space shown on your Mac hard drive or SSD which means that some other partition was created after deletion. 

If you happen to know that a partition exists but cannot find it in Disk Utility, then create an image from this disk using a carbon copy cloner. This way, all files would have been copied at some other place where a new partition might have been created, so even if the old entry has disappeared from Disk Utility, you can still recover the disk image.

Third Party Partition Recovery Software For Mac.

If you need a third-party tool to help recover your 1/2/3 or more data from a lost partition, then iBoysoft Drive Manager can be worth a try. This free partition recovery program is designed for recovering lost partitions from all types of storage devices including HDD, SSD, USB flash drive, and so on Mac. 

Key Features Of iBoysoft Drive Manager for Mac

Able To Manage Hard Drive Easily. It also lets you manage your hard drive by merging, splitting, copying, and deleting partitions or volumes according to your needs. You can copy one Mac volume to another no matter whether the destination disk is an HDD, SSD, USB flash drive, etc. 

Preview Files Before Creation Of Image File. As for people who often use pen drives containing important data to transfer from workstation to workstation, this feature provides a great help since all files can be previewed before the creation of an image file. 

You Can Create An Emergency Startup Disk. In addition, iBoysoft Drive Manager for Mac allows you to create an emergency startup disk with Disk Image created via Clone function which can be used as a boot disk on macOS Sierra/Yosemite/El Capitan and other editions.


Mac comes with a preloaded OS X system, so the whole hard drive or SSD is allocated to this system. And if you are planning to install Windows on your Mac computer, then it would be better to have a separate partition for Windows. Hence, you can allocate some space from Mac’s main partition and create another one that will contain the Windows system.

This way, both the systems wouldn’t affect each other while operating on the same machine hence improving its performance. Although, it is possible to resize partitions live while using your computer but it may also lead to data loss.
