Volume on disk2s2 failed to mount

[jgx_sg1]

[doublepost=1548215323][/doublepost]Hi I was hoping someone could help me. I followed the steps on this thread but got different results.
ExquisisteBeauty4ever:~ exquisitebeauty4ever$ sudo fsck_exfat /dev/disk2s2

Password:

** Checking volume.

** Checking main boot region.

Main boot region is invalid. Trying alternate boot region.

** Checking alternate boot region.

Alternate boot region is invalid.

** The volume could not be verified completely.

Im having the same exact problem and nothing works.

With the following command I'm getting this message. Any help would be appreciated.

TJs-iMac:~ kinh$ diskutil mount readOnly disk3s4

Volume on disk3s4 failed to mount because it appears to be an APFS Physical Store

WHat should I do from here?

Hi utk27,
yes, that's all done in terminal.
Paste each of this codes on terminal and press ENTER for each code.

First you need to find in which port your disk appears. for that type the following:

diskutil list
(This would give you a list of the devices and volumes you have plugged in. In my case it was disk2s2. Then proceed with the following codes)

sudo fsck_exfat /dev/disk2s2

diskutil verifydisk disk2

diskutil mount disk2s2


Let me know if it works. You can paste here what terminal tells you and I might be able to help you further.

Hi there ! I'm trying to perform all those in my Terminal. But got stuck at the password stage. Though I know my system password ! What else could it be ?

After typing this line :
sudo fsck_exfat /dev/disk2s2

You could try this:

Fix corrupted exFAT disk macOS/OSX


from the Terminal:

diskutil list

The volumes listed should show your disk ("rdisk2s1") and possibly its partitions.

Then, copy paste this (replace "disk2") in the example below with your disk's or partition's name (of course, remove "(but your disk)").

sudo ps -ax | grep disk2 (but your disk)

you should get the process number keeping your disk busy:

13699 ?? 11:52.83 /System/Library/Filesystems/hfs.fs/Contents/Resources/./fsck_hfs -y /dev/disk2s2

Then execute:

sudo kill 13699

In the example above, "13699" refers to the process currently busy, but it should be a different number on your machine.

After killing the process, the drive should mount, with a Finder's warning.
