My external device SSD not able to mount for my data files

[Muhammad Umar Farooq]

Dear Sir/Madam,

I was using my previous SSD Hard drive as an external hard drive and was working fine but today unfortunately unable to mount my data files. For further convenience, I am enclosing herewith a screenshot message as I am seeing. "Mount Failed

Failed to mount "127 GB Volume"
Error mounting /dev/sdb5 at /media/linuxlite/ 044f817b-c90b-4713-9339-654368a3f452: wrong fs
type, bad option, bad superblock on /dev/sdb5, missing codepage or helper program, or other error

x Close


I shall be very thankful to someone else who can resolve my external SSD device's failure to mount.

Thanks with anticipation,
Muhammad Umar Farooq

Having a look at the logs may show what is happening as that error message is very general.  Assuming the SSD is in a USB caddy you could do something like this. 

Boot up your system and allow it to sit idle for a while so nothing is going on in the background.
Open a terminal with 'Ctrl Alt T'
Make a note of the system time in the HH:MM format e.g. 17:55
Connect the external SSD.
If it would normally auto-mount allow enough time for this to complete.
Otherwise attempt to mount it as normal e.g. right click and enter password etc

Once the mount operation has failed run these commands in the terminal.
Replace HH:MM with the value you noted earlier.

Code:

journalctl -b --since HH:MM

press space bar to page through the output (or enter to advance line by line) until you see (END), then q to exit

You may get extra information with this command

Code:

sudo dmesg

Edit to correct typing error.

In both cases, you may need to scroll up a bit to find the messages relating to the SSD connection and mount.
A message saying 'New USB device found' would be a typical place to start reviewing.
Check the messages after that and look for any relating to mount errors

Post back with the results if necessary.

Dear Sir/Madam,

I have applied the instructions given by you, but the message display failed in both commands. First output "command not found" Second reply "sudo dmseg command not found"

[stevef]

My apologies.  I made a typing error in the second command - use this

Code:

sudo dmesg

Regarding the first command can you post back with the result of

Code:

whereis journalctl

how i can share the results from the Xfce terminal? Kindly guide me

Sharing the results from a terminal is usually done using the code tags.
When writing a message you should see a number of face icons above the text entry box.
Above those icons are some button icons.
Locate the '#' button and place the mouse over it.  It should say 'Insert Code'.
Clicking once on the # button should place a pair of code tags into the text entry box.
The tags will be enclosed by square brackets.  Anything you put between the tags will be formatted properly in a blue box when posted.  Use the preview option to check what your post will look like.

Posting guidelines can be found at https://www.freecinema2022.gq/forums/intro...uidelines/
Just after the 'Thread Title' section there is a guide to pasting terminal output into the forum using codes tags.

It appears your disk is failing to mount because of corruption, possibly it was incorrectly disconnected on a previous use and the system is suggesting to use fsck.

Accepting advice off the internet is risky.  Research to double check advice offered. Take extreme care when entering commands.  Ensure you have a working backup of your system and essential data.  If the data on the disk is important you may want to get advice locally from a reputable expert.

Your first post referred to 'Error mounting /dev/sdb5' whereas the most recent post refers to 'sdc5'
It is important that the correct parameter is used when trying to fix disk problems.

Identifying the disk and attempting repair may be easier with a GUI.  If you prefer to use a GUI, the tool you need is 'Partition Drives' aka Gparted.  Let us know if you need help with this.

If you prefer to use command line,  start by showing the hard disks on the system with this.

Code:

blkid

Identify the device name used by the external SSD, it will be in the form /dev/xxxx
Make a note of the device and also the TYPE listed.

Post back if you can't identify the drive and TYPE.

When you have the correct device and TYPE for the external SSD, run file system check to see what it reports.
If for example, blkid reported "/dev/sdc5" and TYPE="ext4" for your SSD, you would run the command below, but the command you use may be different.

Code:

sudo fsck.ext4 -v /dev/sdc5

Post back with the results.

should i use the second command if yes, just like given or to be modified?

[stevef]

The second part of your post (since edited) shows you entered "blkid", then "ext4" and then the fsck command exited with "Possibly non-existent device?"

I don't understand where the messages beginning "Force rewrite" come from.  What command was that ?

Should I use the second command just like as you depicted or to be changed if changed please give rewrite command.
