Note that this deletes all files that are currently stored on the USB drive exFAT: Pros and cons. exFAT fixes the downsides of the FAT32 file system regarding maximum file size and partition size. Another advantage is that it keeps the high compatibility with many operating systems and devices. Another upside is the increase in speed when transferring data when compared with FAT32.It's biggest downside is the lack of a journaling feature, which makes it easy to.

The file systems in Linux, macOS, and other Unix-like operating systems don't use separate volume identifiers for storage devices in the way that, say, Windows does. Windows assigns each volume a drive letter such as C: or D: and the file system for each volume is a tree of directories sitting below that drive letter

I can format this card to one huge partition using SD Formatter, but then I get stuck.The problem is, I can't figure out fdisk and parted (the documentation on that is a little tough for me to follow), and gparted isn't letting me resize the one massive partition.

This line sets up the environment needed to boot from the USB drive The Raspberry Pi is a versatile credit card-sized computer that can be used for a variety of electronics projects. The great thing about the Raspberry Pi is that you have the option of installing different operating systems and aren't limited to Raspberry Pi OS.This includes Arch Linux, which is revered for its simplicity The only problem with that is that rsync isn't available on the SD card. Not a problem! A quick dip into wifi-menu followed by pacman -Syy and pacman -S rsync had that problem solved in a jiffy.
