Re: free space before the first and after the last partition if GPT partition scheme is used
Sven,
I see. Thanks! Are those "bios_grub" or "EFI system" partitions
located inside the GPT scheme, i.e. inside the first ~16KiB of the
disk and it is not seen with gdisk? In addition, if this small area
after the last partition is also for alignment purposes, then where is
the backup GPT stored?
regards,
Martin
