VMWare - GPT PMBR after adding a Disk to existing one -GPT PMBR size mismatch will be corrected by w(rite)

we've added a new disk to VMware fusion VM. Below fdisk -l output:

Disk /dev/loop1: 91.4 MiB, 95805440 bytes, 187120 sectors
Units: sectors of 1 * 512 = 512 bytes

How we could resolve the issue without lost existing data? Thanks in advance BR

Run fdisk on it and use w to save the existing partition table without any changes.

All GPT disks have a "protective MBR" which contains a dummy partition covering the entire disk (or as much of the disk as possible). If you grow the disk, this partition will still indicate the old disk size until fdisk adjusts it.

This has no effect on data stored on the disk; it is there only to guard against old MBR-only disk partitioning tools.
