Better data securityĪpple added the journaling feature to HFS+ to improve data reliability in Mac OS X 10.2.2, which soon became the default in Mac OS X 10.3. HFS+ employs UTF-16 to encode files and folders and permits file names up to 255 characters, making it easier to have a descriptive name. Maximum size of a file and a volume: 8 EB Internationally friendly file names Maximum number of files in a volume: 2.1 billion This allows more allocation blocks and a smaller block size, which means less space is wasted. HFS+ uses a 32-bit value to address allocation blocks, two times larger than its predecessor HFS (stands for Hierarchical File System). Features of HFS+ Better use of Disk Space Without file systems like HFS+, saving a file to a drive is like throwing a rock into the sea, impossible to be found. It creates a directory that expands as files are added to the drive and records metadata and file names.

You can't read or write to a Mac-formatted external hard drive on a Windows PC because your Mac drive is usually formatted with HFS+ or APFS, which is incompatible with Windows.

All Mac operating systems since Mac OS 8.1 (read & write support).

(Your Mac must be connected to the SMB server when you set up Time Machine.) After you select the network disk in Time Machine settings, Time Machine automatically connects to the disk when it’s time to back up or restore your data. If your backup disk is on a network, the network server can use SMB file sharing. After you set up the network disk in Time Machine settings, Time Machine automatically reconnects when it’s time to back up or restore your data. If your server does not support Time Machine Bonjour notifications, you may still be able to set it up as a Time Machine destination by connecting to the server using SMB and then selecting the mounted network disk. If your network server or NAS device supports Time Machine Bonjour notifications, you can set up Time Machine backups even if you are not connected to the server. If the disk uses the Master Boot Record (MBR) partition type, some partitions may not be available for use with Time Machine.

Time Machine still supports backups on Mac OS Extended format (Journaled), Mac OS Extended (Case-sensitive, Journaled), and Xsan formatted disks. The two volumes then share the available space. If you want to store files other than the Time Machine backup on the same physical device, use Disk Utility to create an additional APFS volume on the disk. Note: The entire APFS volume is reserved for Time Machine backups.
