fdisk was historically limited to MBR. While modern versions of fdisk support GPT, gdisk was built from the ground up for GPT, making it inherently more robust for this standard.
parted executes commands immediately, which can lead to accidental data loss. gdisk uses an interactive menu with a confirmation step.
gdisk performs all operations in system memory. Changes are written to the physical disk only when you explicitly execute the write command. gdisk vs. GNU Parted fdisk was historically limited to MBR
Press v to run a verification check. Ensure no errors are reported. Press p to double-check your planned layout.
Destructively or non-destructively transforms MBR disks into GPT disks without losing existing data. gdisk uses an interactive menu with a confirmation step
Checks the disk for partition overlaps, invalid structures, or mismatched headers. Write table Commits all pending changes to the physical disk and exits. q Exits the utility immediately without saving any changes. ? Prints the complete menu of available standard commands.

: Copies the backup GPT structures back into the primary header space to repair corruption caused by sudden system power losses. gdisk vs
To launch gdisk , pass the target storage device path as an argument via your terminal (requires root privileges): sudo gdisk /dev/sda Use code with caution.
