What is the command you use for mounting this disk?

1... mount -o ro,noexec /dev/sda1 /media
2... mount -o ro,noexec /dev/sda1 /exthdd
3... mount -o rw /dev/sda1 /media
4... mount -o rw /dev/sda1 /exthdd

tried all 4, plus clicking on the exthdd icon in file manager.

thanks.

What about "lsblk -f"- use sudo in need.

I found this......

The ext4 feature (400) is the new metadata_csum feature. If this feature is enabled and old tools are used to mount the filesystem they will only be able to mount read-only.

https://ext4.wiki.kernel.org/index.p...data_Checksums

To create a ext4 filesystem without this feature:

sudo mke2fs /dev/sdb1 -O ^metadata_csum
Or turn it off on an already created filesystem:

sudo tune2fs -O ^metadata_csum /dev/sdb1

Yeah, something like that was very likely. Maybe mount it as ext3 ?.

I have 1.5 Terabytes of files on there.

Could remounting it cause any files to get destroyed?

This failed: sudo tune2fs -O ^metadata_csum /dev/sdb1; I changed sdb1 to mine. Mentioned something about having a ro permission on there.

I have mounted in ro many times and sometimes when I would remount it as rw, it would still be holding on to the ro. I would restart the machine to get it to clear.
