Hi All,

Fedora 26
BIOS boot = legacy (EUFI give me hives)

I have a SATA backup drive formatted gpt, one partition, xfs. I went into gparted, erased the partition, recreated the partition as ext4 and formatted it as ext4.

Then I mounted it as ext4, copied some files to it, unmounted it. When I went to remount it, mount told me there was something wrong with ext4.

What "something" was that?

mount: /lin-bak: wrong fs type, bad option, bad superblock on /dev/sdd1, missing codepage or helper program, or other error.

       In some cases useful info is found in syslog - try
       dmesg | tail  or so
       ^^^^^^^^^^^^

What is the official way to remove an xfs partition?

It's not usually needed, but if you don't want the kernel and/or utilities to recognize an xfs block device as xfs anymore, simply zero the first 512 bytes of that block device.

I can do that!

I was concerned about the gpt stuff at the end of the drive.
Ignored if I clobber the first 512 bytes?

The filesystem signature on a partition is a separate issue from
the partition table signatures on the disk...
