[SOLVED]500 GB HDD Partitioning

anon298 · 02-23-2023, 02:10 PM

Just for giggles, I checked the partitioning of the 500 GB SSD on my laptop, which is:

/dev/sda free space (1.1 MB)
/dev/sda1 partition 1 (537 MB, fat)
/dev/sda2 partition 2, file system (500 GB, ext4)

The laptop seems to function okay, but I do wonder why /dev/sda1 is formatted as fat. Is it something I DID? Any ideas?

Thanks, guys.

open a terminal and post the output of

Code:

df -h

if sda1 is mounted at /boot/efi, you have a uefi system and sda1 is the efi partition where the bootloader code is stored instead of the mbr of the drive as is done in legacy mode. google "uefi vs legacy" if you want to know more.

It's probably the EFI System partition. The UEFI specification says that they have to use FAT.

Here ya go, colorpurple21859:

Filesystem Size Used Avail Use% Mounted on
tmpfs 384M 1.5M 383M 1% /run
/dev/sda2 457G 18G 416G 5% /
tmpfs 1.9G 0 1.9G 0% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
/dev/sda1 511M 6.1M 505M 2% /boot/efi
tmpfs 384M 104K 384M 1% /run/user/1000
