Perhaps this can be a RFE for not printing the table if the EFI PART label is not there. The fdisk tool says that GPT support is in experimental phase. I'd say the expected results are the printing results we get from parted.

But when a user wipes a label, they are expecting a clear disk. I realize that both tools are likely doing what they are intended to do. wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid. I/O size (minimum/optimal): 512 bytes / 512 bytes Force wipe, even if the filesystem is mounted: sudo wipefs -all-force /dev/sdX tldr.sh.

Trying to clear a disk while doing the installation or to ensure other disks can be cleaned to use for Longhorn Describe the solution you'd like Include fdisk, parted, wipefs. Sector size (logical/physical): 512B/512B Type the following command: sudo wipefs /dev/sda. Version-Release number of selected component (if applicable): Just looking for clarity, would be glad to change the component if needed. I don't know whether fdisk needs to identify GPT partitions differently or wipefs needs to clear the '55 aa', but we should not be seeing a partition table after wiping the label. If I clear the '55 aa', it ceases to report it.

If thats the case, change the command below to wipefs -af to force wiping even. Fdisk is printing a partition table with label type dos and System GPT even after clearing the 8 byte GPT label with the wipefs tool. Take note of whether you see nvme in any of the outputs.
