Perhaps this can be a RFE for not printing the table if the EFI PART label is not there. You cant actually ' delete ' unallocated space instead, what you can do is the following: 1) Move existing partitions to the left to consolidate the unallocated space. if labelclear doesn't work, you need to use dd if/dev/zero to zero out the first x amount 100mb-1g whatever, and then the end of the disk as well then reboot. You'll probably need to erase the end of the disk as well. When used without any options, wipefs lists all visible filesystems and the offsets of their basic signatures. wipefs does not erase the filesystem itself nor any other data from the device.

The fdisk tool says that GPT support is in experimental phase. ZFS places four 256KB vdev headers on disks, two at the beginning and two at the end. wipefs can erase filesystem, raid or partition-table signatures (magic strings) from the specified device to make the signatures invisible for libblkid. 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. Rest should be very similar to gdisk (n to create partition, t to set partition type etc.). You can create a GPT partition table with g with fdisk. If the problem you are having is that SD (mmc) is not mounting during preinit, but only during regular boot, then you need to file a proper report of that bug, without doing a. Partitioning tools usually don't wipe the filesystem signatures, fdisk also doesn't do that when deleting the partition, you should use wipefs.

It is used for the view, create, delete, change, resize, copy and move partitions on a hard drive using the dialog-driven interface. Just looking for clarity, would be glad to change the component if needed. -W, -wipe-partition when: Wipe filesystem, RAID and partition-table signatures from a newly created partitions, in order to. fdisk also known as format disk is a dialog-driven command in Linux used for creating and manipulating disk partition table. 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. 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.
