About Mac's Disk Utility

Disk Utility is a system utility for performing disk and disk volume-related tasks on macOS and Mac OS X systems. With this easy-to-use program, you can perform tasks as the following:

1. Mount, unmount, and eject connected hard drives including SSDs.
2. Create, resize, and delete partitions by allocating space of storage devices.
3. Erase and format disks with multiple file system options supported.

6. Verify a disk's integrity and repair it with First Aid if the disk is damaged or corrupted.

Disk Utility brings more insights into disk management on Mac, on condition that you use this tool in the right way.

Problems after a misuse of Disk Utility

Of course, you can perform many disk-related tasks with Disk Utility, simple and easy. But the risk of using Disk Utility is also an important part that you should know. If you don't use Disk Utility in the right way, you could get into trouble. Usually, there are three possible problems.

1. Data loss after using Disk Utility

Your documents, emails, photos, music, movies, etc. could get lost after your misoperation. If you don't back up the data, you'll lose files after you erased a hard drive, deleted an APFS volume, or formatted a partition.

So, be careful with these options mentioned above and always back files up. Photoshop 2020 for mac crack. The gametools suite cracked.

2. Disk corruption

Except for files being deleted, what's worse is that the hard drive itself is corrupted. For example, you should always choose the Eject button before removing an external hard drive. If you don't, the risk of disk corruption is increased. The next time you want to access the external hard drive on Mac, you could receive an error message like 'The disk you inserted was not readable by this computer.'

3. System crashes

The worst case is system crash because you deleted one of the key partitions in the startup disk. For instance, when you add a new partition to the internal SSD, some core partitions could be deleted by the system in rebuilding the partition table.

For Macs whose startup drive is formatted with HFS+, the MacBook won't turn on after a wrong deletion of disk0s1 or the EFI boot partition. Similar things happen to APFS formatted boot drive as well, especially for Macs that have the Apple's T2 security chip. If you accidentally removed volumes like Recovery and VM, MacBook or Mac mini introduced after 2018 will have boot problems. It's because the T2 security chip fails to verify the integrity of the boot process.

So, if you see unknown volumes listed under the startup disk, always check through this volume before you finally remove it. Also, you should pay more attention when you want to re-partition the internal hard drive.
