Please tell how to mount a SATA drive with R/W permissions.

Ghostly

I have Ghost BSD 15.02 (GBSD)and can mount and read from,
but not write to, the SATA drive previously written under
MX-Linux with EXT4 file system.

I may wish to swap operating systems on the main drive while
retaining my user data on the EXT4 drive as if it were home.

Under GBSD when I start to edit a file on the mounted drive
a message appears "Read-Only file system" and I must
save the file under another name. (It allows a write operation.)

I have searched the Software repository but cannot find
a program which allows BSD R/W access to EXT4-written files.

It is not SATA centric explanation; Use GPART command to see disks that are available.

Use ext4 Fuse File. Let me understand and find a source to share with you.
man mount # read the manual page for the " mount" command
mkdir /mnt/tmp_ext4
gpart status
gpart show -lp
gpart show -rp
mount -rw /dev/ada01 /mnt/tmp_ext4 #if device is /dev/ada01

To mount an EXT4 SATA drive read-write in FreeBSD, you must first disable the journaling feature on the EXT4 partition (using a Linux system or live boot) because FreeBSD's native module does not support journaling. [[1](https://forums.freebsd.org/threads/mounting-ext4-drive-in-14-0.91010/), 2]

FreeBSD supports EXT4, but you may need to load the module into the kernel. Run: [[1](https://docs.freebsd.org/en/books/handbook/filesystems/), 2]

Thanks for your reply. Since my request I have read a discussion on this site about why GBSD does not natively support EXT4 - Sounds like an unreliable exchange of data between the two file systems.
Thank you again for your reply. I'll have to read up on this topic.

This may not explain anything, but in the Xfce edition I have full access to a second HDD that has a Linux distro installed and all the files are in ext4 format:

I can open that icon and access everything on that drive from Thunar in GhostBSD.
