In this case, you can use other tools instead of Disk Utility. Disk Utility will report MediaKit reports not enough space on device for requested operation. This error occurs because the partitions created do not comply with Apple’s partition policy. In another case, if you are using a Seagate, WD My Passport or any other hard drive that you previously partitioned with another tool.

If you are a Linux user or operating systems other than macOS, you probably use another tool. Disk Utility only supports partition creation and formatting for Mac OS Extended (Journaled), exFAT, MS-DOS (FAT) and since MacOS High Sierra (10.13), it supports APFS.

It supports creating, splitting, merging, resizing, deleting and formatting partitions on the hard disk. Now that leaves me to Mac OS (Case-sensitive) vs.Are you having trouble creating Mac OS Extended (Journaled) and APFS partitions using Disk Utility? If so, you can create a Mac OS Extended partition using GParted, then convert to APFS using Disk Utility.ĭisk Utility is a disk utility on macOS operating system. Mac OS (Case-sensitive, Journaled)? Any advice? Now that leaves me to Mac OS (Case-sensitive) vs. It will also attempt to restore any unsaved documents that you were working on at the time of the power failure. If your Mac should go down, due to, for example, a power outage, when you restart your Mac, the Mac OS will check the journal and will perform a consistency check on the drive's directories and file structure. Journaling is a process whereby the Mac OS keeps an eye on what you are doing while you work, it keeps a journal, keeping track of changes you have made to your files. Journaling was developed primarily for Mac servers to protect the integrity of the disk Directories and file systems. If you will be using the drive as a media or 'scratch' drive, for video editing, then you would select Mac OS Extended, journaled not selected, as the journaling process slows down the write speed performance of the drive. If you are going to use the drive as a system or 'boot' drive, with the Mac OS on it, then you would want to select 'Mac OS Extended (Journaled)'. The format that we chose, 'to Journal or not to Journal' depends on what the drive will be used for.

I came to learn that Mac OS Extended (Journaled) and Mac OS Extended.

I just would like to know if there are other alternatives. I know that Mac OS (FAT) is compatible with both PC and Mac platforms, however, there's a limit to trasnferring files to 4GB. I guess my real question is the difference between all four of the following options: Mac OS Extended, Mac OS Extended (Journaled), Mac OS (Case-sensitive), and Mac OS (Case-sensitive, Journaled) when reformatting an external hard drive?
