You seem to have progressed.
Does the SSD mount now or is it still failing ?

[Muhammad Umar Farooq]

It is still not mounting for your convenience message file enclosed

[stevef]

I think it might be a good idea to a clean start and post back with the dmesg output and the journalctl output so that we can see if anything is different.

the below is result after applying sudo dmesg and whereis journalctl commands

With the SSD connected, run this command in a terminal - enter your password if asked.

Code:

sudo fdisk -l

This command with the -l option lists partitions connected to your system.
Next, run this command

Code:

lsblk

This command lists block storage devices connected to the system along with mount status
Please post the results of both commands.

Without adding or removing any devices so that the sdc device doesn't change, please run these commands to examine the block information on the SSD
You may need to enter your password

Code:

sudo dumpe2fs -h /dev/sdc5

Code:

sudo dumpe2fs /dev/sdc5 | grep superblock

Post back with the results

Edit - Typo was "dump2fs" in original. Corrected to "dumpe2fs"

My apologies for another typing error.  I have edited the mistake in my earlier post.

The commands should have been

Code:

sudo dumpe2fs -h /dev/sdc5

Code:

sudo dumpe2fs /dev/sdc5 | grep superblock

You need to check and confirm that the SSD is still at /dev/sdc5 and not mounted.

I don't know what scalpel is - sorry.  If you wish to go down another path to try to solve the problem I completely understand.
