External harddrive detection

[Orestesss]

HI all,

I have an issue with an external USB harddrive (1TB in size). Mageia3 (64bit) detects it, but when I open my Dolphin, I get the message "could not enter folder /run/media/.../825a68d4-aa21-4e17-a52b-2e017e6a1839". The contents of the harddrive are not displayed. The harddrive did work under Ubuntu, and is detected under Windows also.

Anyone know what the cause and the solution could be?

Many thanks, in advance!

Is the HDD encrypted ?

Please post the output of in a console(whilst hdd pluged in and switched on)

Code: Select all

lsusb

and

Code: Select all

cat /proc/mounts

Does seem to be seeing it if it has a mount point added.
however its handy to follow the messages log when you plug something in that's causing problems.

To do that in a root console type

Code: Select all

su -

enter root password
then type

Code: Select all

journalctl -f

When you fist plug it in you should see something happening.


post output that's generated, will give me and others incite too

Hiya,

The harddrive is not encrypted. To my knowledge, so I suppose not.

External harddrive doesn't appear in the log from journalctl. Did you run journalctl as root, and did you plug the drive only after journalctl -f was running?

[Orestesss]

I ran it as root, but the harddrive was already plugged in.

When logged in as root and plugging in the HD after, I get this:

[doktor5000]

Looks much better. Can you do an

Code: Select all

fdisk -l /dev/sdb

as root now that it's attached?

[Orestesss]

This yields:

Disk /dev/sdb: 7971 MB, 7971016704 bytes, 1946049 sectors
Units = sectors of 1 * 4096 = 4096 bytes

Do "ls -l" to check the owner and properties of the disk. Perhaps your user does not have access to it.

Personally I often run into these kind of issues since I use user "id" number for my disk rights instead of a user name. Then if I was clumsy enough not to use the same user ID for my user in a new installation or another distro I cannot access the disk!

Can you read the disk as root in a terminal? That is the easy way to check.

[Ken-Bergen]

Do "ls -l" to check the owner and properties of the disk. Perhaps your user does not have access to it.

As it's a FAT32 partition it has no unix style permissions.

When mounted the mount point and all directories and files under it are given temporary read/write permissions of whomever mounted it.
These permissions are not and can not be written to the disc.

The only time I would expect to see this problem is if user A mounted the disc then user B tried to access it.

The folder you mount it in does have Unix read/write permissions. I have had the same problem with Fat32 as well. Just because the run folder didn't have the correct user. But that might be my own fault as I have myself managed these disks to get them to only be accessed by the user ID.

Still worth checking though... Perhaps something is wrong.

In any case I would do in terminal as root user "export $(dbus-session)" then "dolphin" to run dolphin as root and check if you can access the disk.

[Ken-Bergen]

OK, when I go in a terminal and try to access the drive there (as su), I have access. So it may be a Dolphin thing?

Entering "dolphin" yields:

Code: Select all

dolphin(11899)/kdeui (kdelibs): Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)
KCrash: Application 'dolphin' crashing...

When I then type "export $(dbus-launch)", Dolphin does launch in the GUI, and I can access the drive. Seems a bit convoluted though, and apparently I would need to do this every time, as when I shut off the drive and turn it on again, the same problem pops up again too.. :s

[Ken-Bergen]

If you use

Code: Select all

su -

you get a complete root environment able to run graphical programs such as dolphin.
Of course this has nothing to do with your original problem.

[zeebra]

If you go into /run/media/{yourusername}/

type in ls -la to see what permissions the folders there have. The name of the folder should be a bunch of numbers and letters or "uuid" name. It should be owned by your user, not root or someone else.

Ps. Sorry "export $(dbus-launch)" is the correct command. I wrote it without the dollar sign.

[Orestesss]

Is it an option to re-format that harddrive perhaps? I've been trying Krusader instead of Dolphin, and that gives the same problem....

Even running "export $(dbus-launch)" does not always work, or sometimes only temporarily. And that means that this harddrive is a b*tch to use, so I tend to avoid having to do it. That shouldn't be so, I want my devices to work...

So if buying a new harddrive perhaps, what should I pay attention to? Not buying FAT32 drive, for instance? Would I have these issues with solid state drives?

Thanks.

[doktor5000]

You didn't answer about the question from zeebra on the permissions of the mountpoint.
Also, when the disk is mounted, please show the output of

Code: Select all

mount
