View Full Version : [ubuntu] Cannot mount volume error!
Questioneer
July 7th, 2008, 02:23 AM
Hello. I get the following popup when plugging in a portable USB drive, or a couple USB sticks.
"Cannot mount volume.
Invalid mount option when attempting to mount the volume."
CDs and DVDs are fine. I've used Hardy before on this computer without this problem before, but I reinstalled it again yesterday.
The problem could lie with the fact that I installed Hardy from a USB drive, But I'm not sure.
Thanks,
Questioneer

Using GNOME on ubuntu 8.04, of course. I assume this is a Desktop Environment problem, But I can't tell.
Any help?
thanks,
Questioneer

I'm not sure that this will work, as I'm kinda new to Ubuntu 8.04, but, you can mount it manually;
Step 1)
Plug in your usb device
Step 2)
Open terminal (Applications > Accessories > Terminal) and write in
ls /dev/disk/by-label -lah
Step 3)
The result should look kinda like this;
total 0
drwxr-xr-x 2 root root 60 2008-07-07 15:04 .
drwxr-xr-x 6 root root 120 2008-07-07 15:04 ..
lrwxrwxrwx 1 root root 10 2008-07-07 15:04 \xe7\x9dL3\xea -> ../../sdb1
Step 4)
Write this into terminal;
pmount /dev/sdb1 USB
Note: Change sdb1 in the command in step 4 to whatever comes up on step 3.
E.g, If the result in step 3 was
total 0
drwxr-xr-x 2 root root 60 2008-07-07 15:04 .
drwxr-xr-x 6 root root 120 2008-07-07 15:04 ..
lrwxrwxrwx 1 root root 10 2008-07-07 15:04 \xe7\x9dL3\xea -> ../../sdv7
then put
pmount /dev/sdv7 USB into terminal...

Hello.
OK. I have no dev/disk/by-label, so I used dev/disk/by-id
Then, I got:
lrwxrwxrwx 1 root root 9 2008-07-06 19:49 ata-WDC_WD1600JS-75NCB1_WD-WCANM2138805 -> ../../sda
lrwxrwxrwx 1 root root 10 2008-07-06 19:49 ata-WDC_WD1600JS-75NCB1_WD-WCANM2138805-part1 -> ../../sda1
lrwxrwxrwx 1 root root 10 2008-07-06 19:49 ata-WDC_WD1600JS-75NCB1_WD-WCANM2138805-part2 -> ../../sda2
lrwxrwxrwx 1 root root 10 2008-07-06 19:49 ata-WDC_WD1600JS-75NCB1_WD-WCANM2138805-part5 -> ../../sda5
lrwxrwxrwx 1 root root 9 2008-07-06 19:49 scsi-1ATA_WDC_WD1600JS-75NCB1_WD-WCANM2138805 -> ../../sda
lrwxrwxrwx 1 root root 10 2008-07-06 19:49 scsi-1ATA_WDC_WD1600JS-75NCB1_WD-WCANM2138805-part1 -> ../../sda1
lrwxrwxrwx 1 root root 10 2008-07-06 19:49 scsi-1ATA_WDC_WD1600JS-75NCB1_WD-WCANM2138805-part2 -> ../../sda2
lrwxrwxrwx 1 root root 10 2008-07-06 19:49 scsi-1ATA_WDC_WD1600JS-75NCB1_WD-WCANM2138805-part5 -> ../../sda5
lrwxrwxrwx 1 root root 9 2008-07-06 21:10 usb-Seagate_FreeAgentDesktop_6RY1R4XG-0:0 -> ../../sdb
lrwxrwxrwx 1 root root 10 2008-07-06 21:10 usb-Seagate_FreeAgentDesktop_6RY1R4XG-0:0-part1 -> ../../sdb1
and then I installed pmount, which was not installed.
Then I run pmount /dev/sdb1 USB
Warning: device /dev/sdb1 is already handled by /etc/fstab, supplied label is ignored
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
THEN I run pmount /dev/sdb USB, and no error is given, but nothing seems to happen!
I would like to possibly fix the problem and be able to have GNOME auto-mount if I can.
Thanks,
Questioneer

Also try:
Code:
sudo mkdir /media/usb
sudo mount /dev/sdb1 /media/usb
Hey! That worked! The drive is now accessible!
Any other drive I put in is also accessible.
Thanks,

Hi Questioneer, I had exactly the same problem of yours.
Recently I installed Ubuntu 8.04.1 image over my 8.04 just for the sake of a clean install - and to test installation through an USB stick. I used UNetbootin, and you?
Well, after that, every time I plugged my USB external drive (ext3) or stick (fat32) I got a "Cannot mount volume." message. I could manually mount them, but Ubuntu automatic mounting was not working..
I noticed strange lines in my fstab file:
/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/scd0 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0
Due to pendrive install (?) the file system /dev/sdb1, which (on my machine) is normally used by Ubuntu automatic mounting, was pointing to cdrom..
So I removed both lines in fstab and added (to preserve the real cdrom):
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
When I rebooted, everything was working flawlessly as when I installed Ubuntu 8.04 from a live cd!

Thanks a Lot Dude... I searched the whole net but was not getting the solution for 'Cannot Mount Volume'...U solved my Prob...
Problem: I use live USB Ubuntu 9.04 with Persistent... all of a sudden i was not able to mount 2 of my 1st NTFS partitions of 2 HDDs... Dont know why...
This Worked:
sudo mkdir /media/Backup
sudo mount /dev/sdb5 /media/Backup
Backup is my Volume Lable for that partition...
Though spaces are not acceptable for volume lable
For my second disk i tried
sudo mkdir /media/Windows XP
sudo mount /dev/sda1 /media/Windows XP
And i got a error...it was not done
so I changed 'Windows XP' to 'WindowsXP' & i was able to mount the volume.
Thanks Again
