access to extern HD?
« on: January 13, 2011, 06:11:00 PM »
I've got an extern (USB) HD. When I start it up it appears in the filebrowser, but I can't read the contents - I got the error message "Rättigheter saknas" ("no rights"). I can't mount it, even if I log i as root, and it has a mountpoint (/mnt/nethd.  The only way to mount it is to open PCLOS control center and "local disks - manage disk partitions" . It has the name "sdb", and there I can mount the partition.

How do I change the settings so I can mount (and read/write) the disk without using the partition manager?

First, one does not mount a hard drive, one mounts a filesystem on a partition on the drive. We need to know what filesystem and what partition you are trying to mount.

Is the drive new, or have you had it for a bit? What filesystem? NTFS? EXT3? FAT32? How large is it?

It should just auto-mount, so the more info you can provide, the simpler you make it to work out what the issue is. :)

If you have dual boot, the boot windows, plug the hd. Close all folders and press the button "safety remove usb device. It should be somewhere by the clock. That did work for me.

So, a week and not even replied to your own thread? Pretty weak.

sorry for the delay.

The drive got one partition. It is NTFS-3G and 74 GB.
I have made a mount-point for it at /mnt/nethd

I have used it for a while, and it contains backup files.
I want to use it with the "luckyBackup" program ehich needs a searchway from root, that's why I made the mountpoint. Perhaps I should not make a mountpoint for a removable disk, but how shall I then find it in the filesystem?

If you give the it a unique label (let's call it LABEL, for now  ;)), and let HAL manage it so it can be auto-mounted, then you will be able to consistently locate it at
Code: [Select]
/media/LABEL/

I don't know what HAL stands for. ???  But I have already made a mountpoint at /mnt/nethdd with the partition manager.
I forgot to tell that the disk is usually turned off, and when I want to use it I turn it on when I am already logged in. The dialog box turns up asing me how to handle the new device, and when I click at "open the folder" it can't mount the disk. At the moment the disk is at my job so I cant try anything now. I think it's label is "nethdd".

HAL stands for Hardware Access Layer, and it is a sub-system that handles accessing your hardware.

For removable media, if there are no pre-existing configurations (such as fstab entries, etc), then when they are inserted, the OS will handle auto-mounting them (within the confines of the DE - Desktop Environment), using a generic name if nothing else is available, but the label will be used if it exists, allowing for consistent access.  These mount points get created and removed, on the fly, within /media/, as required...

But it already does that. When I start it I can see it at media:/diskname, but when I click on it it opens an empty folder and says that I have no permission to mount it.

Also, with the drive mounted, try posting the output of
Code: [Select]
cat /proc/mounts

Yes, it is in the fstab-file:
Quote
# Entry for /dev/sda1 :
UUID=820CF2860CF2750F /mnt/nethd ntfs-3g user 0 0
I don't have the disk here right now, bu tI will try that as soon I have it here again.

external mass storage devices are not supposed to have entries in fstab.

Try to uncomment ints entry,plug in the mass storage device and click on it from dolphin/nautilus to mount it and a mount point will be automatically created in "/media" folder and the mount point will use the label on the partition.

In your first post, you said the partition has "sdb" on its name when you mount it using PCC, that line you posted says the "UUID" is for "sda1" partition. There is a discrepancy here, can you look into it?

I had a 1tb WD External HDD that wasn't recognized by any OS. I just RMAed it and got a new one.
