Why Is It Useful To Know The Format Of Your External Hard Drive On Mac
When you plan on using an external hard drive or SSD on your Mac it pays to know what format your drive is in.
Because your Mac will only read from certain drive formats. And can read and write your files to other formats.
And when you want to use Time Machine to backup your Mac or your Files. Then it’s worth knowing because Time Machine only backs up to a certain external drive format.
So What Are tThe External Drive Formats And Which Can You Use On Your Mac?
APFS, Apple File System – Is a format Apple created particularly for the faster SSD drives. Your Mac can read and write from APFS drives. But you can’t do a Time Machine backup to APFS formatted external drives.
HFS+, Hierarchical File System – Also known as Mac OS Extended (Journaled) File system has been around on Mac’s for several years.
Your Mac can read and write to HFS+ formatted external drives. And you can use HFS+ formatted external drives for a Time Machine backup.
ExFAT – Is a PC file system format but your Mac can read and write to ExFAT drives. But you can’t use Time Machine to backup to an ExFAT external drive.
The real beauty of ExFAT is that a Windows PC can also read and write files to an ExFAT drive. It’s the perfect file system to choose if you want to share files between a Mac and a Windows PC.
NTFS – Is a PC file system format. Your Mac can read NTFS formatted external drives but can’t write to NTFS.
And this means you can’t put files onto an NTFS formatted external drive. Or update files that are already on there.
But you can buy 3rd party driver software for your Mac. Or sometimes this software comes with the external drive. And that software translates for your Mac. So that your Mac can read and write to the drive.
But you won’t be able to do a Time Machine backup to an NTFS formatted external drive.
FAT32 – Is a very old PC file system that’s slow and has file size restrictions.
And it’s pretty insecure.
Macs can read and write to a FAT32 formatted external drive. But these days it’s not a recommended file system to use.
You can’t do a Time Machine backup to a FAT32 formatted external drive.
The good news is that any external hard drive can be reformatted on your Mac. So if you find yourself with a drive, and there are no files on there. You can reformat it to what you want.
