"Failed to Mount 1GB Volume" in SAM LInux (PCLinuxOS)

distortedstar · 04-25-2007, 01:59 AM

So...never had this happen before, but I can't mount my 1gb SD card when in drive-mode on my Palm handheld.

I get the following error:

Code:

"Failed to Mount 1GB Volume"
Given device "/org/freedesktop/Hal/devices/volume_part1_size_1015775744" is not a volume or drive.

Dmesg:

Any ideas? I would love to install this distro permanently, but if I can't access my card...it's pretty useless.

You might want to check the filesystem on the card. If it is fat32, then "sudo /sbin/fsck.vfat /dev/sda1" if it is detected as the same device the next time you plug it in. Your fsck command may be located somewhere else. Please read the "man fsck" manpage first.

A handy command to use to examine a partition is the "file" command:

Code:

sudo file -s /dev/sdc1
/dev/sdc1: x86 boot sector, mkdosfs boot message display, code offset 0x58, OEM-ID " mkdosfs", sectors/cluster 8, Media descriptor 0xf8, heads 125, sectors 7873938 (volumes > 32 MB) , FAT (32 bit), sectors/FAT 7675, serial number 0x458159d0, label: "           "

You might also want to give the device a label. You can do that for a fat32 partition using "mlabel" which is part of "mtools".
You may need to add a line like
drive e: file='/dev/sda1'
to the mtools.conf to assign a drive letter to the partitions device file.

I just tried it out, by adding a label to a 4 GB card. I gave it the label "podcasts". It now automounts under /media/PODCASTS when I insert it.

Thanks for the reply.

dosfsck -r /dev/sda1 returns:

Code:

dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/sda1: 3 files, 2/61981 clusters

file -s /dev/sda1 returns:

Code:

/dev/sda1: DOS executable (COM)

mlabel -n c

almcard returns:

Code:

Total number of sectors not a multiple of sectors per track!
Add mtools_skip_check=1 to your .mtoolsrc file to skip this test

tried adding that line to .mtoolsrc, but I get:

Code:

Syntax error at line 1 column 20 in file /root/.mtoolsrc: unrecognized keyword

I tried reformating the card on with the palm OS with no luck.

Then, I did an fdisk /dev/sda1 followed by mkfs -t vfat /dev/sda1.

Now, I get this error:

Code:

Unable to mount "1G Removable Volume":

Mount operation claims to be successfull, but kernel doesn't list the volume as mounted

Well, I think this could be progress.

Did mkfs -t vfat -n PALMCARD /dev/sda1

This was successful, now "PALMCARD" pops up on the desktop. When I try to mount it, though I get this error:

Code:

Unable to mount "PALMCARD":

You are not privileged to mount the volume "PALMCARD"

I am also UNABLE to mount through thunar as root. However, I am able to mount with the mount command as root in the terminal.

I'll try adding the usb device to my fstab and see if it works.

I reformated with the Palm OS. Same problems as the original post. I now realize that even with the card being formatted by the Palm device I can mount from the command line as root. This looks to be HAL/Udev bug, I guess. Still have to try adding the device to my fstab.

Try using the "user", "noauto" and the "uid" and "gid" options if you are going to add an entry in /etc/fstab. The "user" option will allow you to mount it as a normal user. The "mount" command is an SUID program. If a regular user runs mount, it checks /etc/fstab for the "user" option. If the user option exists, you can mount it yourself. The "uid=" and "gid=" options allow you to become the owner and your default group to be the group owner of a vfat or ntfs partition. Also consider separate "dmask" and "fmask" options instead of "umask". This allows you to set the "x" bit for directories and clear the "x" bit for files. The "noauto" option is needed because it is an external device that might not be present when you boot.

On my system, udev and hal will respect the settings of /etc/fstab when creating the device, mountpoint and ownership, and will still automount the device.

Here's my current fstab entry. Could you illustrate some the changes I might make?

Code:

/dev/sda1 /media/usb-device vfat rw,sync,noauto,user 0 0

I have no problems with a regular usb stick. Just the sd card in the palm. Crazy.

Even more mounting frustration (pun slightly intended):

I tried to mount a data cd and got a "Mount claims to be successful, but kernel doesn't list volume as mounted" error.

Great. Just great. One of reasons I installed a PCLinuxOS dirivitive was the supposed ease of use.
