Unable to mount my usb drive

rmcellig · 06-21-2016, 11:40 AM

I was able to use this drive yesterday but today I am unable to mount it. I tried different cables to no avail. This is what i get:

Code:

randy@lubuntu1520 ~ $ dmesg | tail

I think you should consider a few ideas.

One is to try data recovery maybe testdisk.

Two is to use smart tools to see more about drive. Or use OEM diags for best results.

Those are the kinds of messages you usually see when a drive is dying/dead.

Try with a Live CD and check whether live cd is able to mount.

Hope you have other backups; I would after exhausting more ideas try wiping it, can su*do get at it?

Off topic: Cool jazz by the way!

I do have an up to date backup on another USB drive that I am also backing up using crashplan. I'm also going to check if I can increase my Google drive space as well.

jamison20000e · 06-22-2016, 04:06 AM

Good "crash"plan""

I like as many backups and formats as possible, even pen and paper sometimes... I started switching to (e.g:) Protonmail as well like Blu-ray and other drives.

Sometimes I put or even interpret too much "between the lines" but can you find with

Code:

sudo
(or)
su

your files?

Add: kinda long shot I guess?

I think I may just reformat the drive and see what happens. Gparted doesn't work for me because it can't see the drive.How can I format using the terminal instead? fdisk?

rmcellig · 06-22-2016, 05:18 AM

I take that back! I can see my drive in Gparted. It says file system unknown under file system. Any ideas where to go from here?

rmcellig · 06-22-2016, 05:18 AM

This is what I see when I do information on the drive in gparted:

nable to detect file system! Possible reasons are:
- The fil esystem is damaged
- The fil esystem is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/sdc1 is missing

There maybe better with a USB drive (dd

) I'm not sure but this could do:

Code:

sudo parted -l
(and)
man parted
(then)
sudo parted 
help

specifically:

Quote:

print display the partition table,
rm NUMBER delete partition NUMBER
mkpart PART-TYPE [FS-TYPE] START END make a partition

I forget how to show the partition type, think it is in part of the process or maybe it doesn't use numbers anymore? https://www.gnu.org/software/parted/...de/mkpart.html

Some seems different from the last I used (especially "mkpart PART-TYPE [FS-TYPE] START END"

but am in Sid or it will be more intuitive than I am (e.g: default to stuff for us?

)

jamison20000e · 06-22-2016, 09:52 AM

Okay, I think the (extra) "help" is just confusing me as I don't have something to run it on and see right now?

The bold quotes in my above post should do and then will offer options as it goes...

What is the model of the thumb drive? Is the system even seeing the device with full capacity? It is not uncommon for the controllers to go stupid, making the device useless and the data on recoverable by expensive chip-off recovery procedures.

sgosnell · 06-22-2016, 09:27 PM

It appears that the filesystem is hosed. If the drive has previously had a gpt partition table installed on it, that could be the problem, and gdisk can help with that. But I doubt that's the problem.
