mount exfat -

[Bob Goodwin]

This is an updated Fedora29 workstation and I think I've installed 
thetwo required exfat app's via dnf.

I would like to list the contents of a Western Digital MyBook external 
drive that uses "exfat." Apparently it feels abused by the user when 
unmounted.

[root@Box83 bobg]# mount -t exfat   /dev/sdc1  /mnt/test -o nonempty
FUSE exfat 1.3.0
WARN: volume was not unmounted cleanly.
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option

Perhaps I am not entering the commend correctly?

[root@Box83 bobg]# mount -o nonempty  -t exfat   /dev/sdc1 /mnt/test
FUSE exfat 1.3.0
WARN: volume was not unmounted cleanly.
fuse: mountpoint is not empty
fuse: if you are sure this is safe, use the 'nonempty' mount option

What is wrong?

Here are my observations from my notes:

2019-01-27

[root@Box10 bobg]# dnf install exfat-utils

[root@Box10 bobg]# dnf install fuse-exfat

[root@Box10 bobg]# exfat-fsck

found in release notes"

1.3.0 (2018-09-15)

* exfatfsck can now repair some errors.

Apparently this tries to repair files. It did claim to detect some errors.

as user:

[bobg@Box83 ~]$ exfatfsck /dev/sdc1
exfatfsck 1.3.0
Checking file system on /dev/sdc1.
ERROR: failed to open '/dev/sdc1' in read-write mode: Permission denied.
File system checking stopped. ERRORS FOUND: 1, FIXED: 0.

as root:

[root@Box83 ~]# exfatfsck /dev/sdc1
exfatfsck 1.3.0
Checking file system on /dev/sdc1.
WARN: volume was not unmounted cleanly.
File system version           1.0
Sector size                 512 bytes
Cluster size                  1 MB
Volume size                3726 GB
Used space                 2913 GB
Available space             813 GB

It stopped at this point and I waited a while, nothing seemed to happen, 
did CTRL-C. Tried a second time and had the same result. It appears to 
have found something it can't fix?

I am assuming "exfat" is a work in process and probably can not deal 
with this mount problem.

I will probably just re-format and erase the drive.

The errors you listed, aside from the unclean dismount, shows there is
something existing inside the folder where you want to mount it.  I have
not seen anything you mentioned to dissuade this point.  Check that you
don't have anything at the mount point.  Fixing an unclean disk is
possible.  Most of my experience has been through CDrescue which
automagically cleaned the disk of this error when mounting it, and it has
been too long for me to remember the cleaning process. Perhaps fsck will do
the trick.

.
That was a good thought. I shut down an external drive connected to the 
router, also /dev/sdc1, and immediately had access to /dev/sdc1 in the 
WD MyBook.. And Fedora now has no trouble reading the exfat files, can 
display images, etc.

Thanks for the suggestion,

Bob
