How to Reformat External Hard Drive for Mac
« on: February 01, 2019, 10:05:40 AM »

This article describes the ways to reformat external hard drive on mac without losing data.
Why do I need to reformat external hard drive ?
External hard drive is useful that can be very convenient to help us to backup, store data and transfer files among computers. Which helps conserve storage space on your hard disk and move files quickly. But it is not always so fluent to move files between Mac and PC, namely, between macOS and Windows. The two different operation system have different default file system: the default file system on Windows is NTFS, while it is HFS+ or APFS on macOS. It should be noted that the HFS+ and APFS are not compatible with Windows and NTFS is read-only on macOS. In order to make our external hard drive seamlessly work on both Mac and PC, we need to format our drive to a file system supported by both platforms, so the contents can be read on both platforms.
Which file format should I use?
You can choos a file format that's right for your circumstances based on the operating system and storage content you use frequently.
 
1. APFS (Apple File System) - This is the new file system that Apple bought to Macs with High Sierra and it will be the default if you are using that version of macOS. It is being more efficient and more reliable. But it won't be readable or usable by a Mac that isn't running High Sierra, and Windows won't be able to read or write either.
 
2. MacOS Extended (also known as HFS+) - If your Mac isn't updated to High Sierra it will be the default file system on the Mac. You can encrypt your drive and require a password to access it. There's also an option of MacOS Extended (Case-sensitive, Journaled, Encrypted) if you are likely to have file names that require capital letters. Windows can read HFS+ drives but can't write to them. However, It is a good choice if you are likely to reformat external hard disk and don't want anyone to access the contents of the drive should you accidentally lose it.

I recently transferred all my files off my laptop to a WD external hard drive. Now when I do a search for files, pics, etc, it always comes back with 0.  How can I search the external hard drive? I run windows 8.

Many thanks
