There are many reasons why you may want to format an external HDD or small flash drive. For instance:
- You brought a new unformatted hard drive
- If the drive is not properly formatted, it won’t work
- You want to use your external hard drive in both MAC, PC and Linux (use FAT32)
- Before you sell your SDcard or Pendrive, you should format it to erase its data
- Your camera’s SD card (FAT32) can only hold a file up to 4GB file. To get larger file size format it to exFAT.
Warming: Formating a drive, also erase its data. Although you can still get it back, but it’s much harder after formatting. So if you can’t afford losing you data, take backup.
Which Format to choose?
Choosing a right file system is a bit tricky, so here are some pros and cons of all file system.
NTFS: This is windows propriety file system. Most external drives come preformatted in NTFS so that they can be used easily with Windows. However, NTFS drives are read only in MAC, but you can get write access by using software like NTFS-3g. It also works in Linux. And to support NTFS on Android use Stick mount or Paragon NTFS, HFS and exFAT.
HFS+: This MAC propriety file system and is used in iOS and MAC. If you format your external hard drive to HFS, you can use it on MAC and Linux (by removing journaling). However, to use it on Windows you can HFS explorer (read only).
ext4: This is a default file system for linux OS (including Raspberry Pi). To read an ext4 drive on Windows, you can Ext2Read and OSXfuse for MAC. However, I have not really use this format much, so we just skip it.
FAT32: This oldest file system and work with all OS i.e. Windows, MAC, Linux, Android, even TV, and PS3 etc. This is why it’s used in all small flash drive. Although it lacks all modern features and comes with 4 GB limit for single file size.
exFAT: is the extended version of exFAT. It works fine with Windows and MAC (all the modern version). For Android, you can use Stick mount app (root needed). However being a windows propriety file system, it does not play well in open source environment. But unlike FAT32, it does not have 4GB limit for single file size. Thus making it ideal for SDcards of the high-end camera.
