Can't Mount Partitions (Even after re-installing HAL)

**Israel** · 03-06-2007, 07:12 AM

Ok, I did some reading up on this one first. I saw most people with this same problem after installing Knoppix to the hard-drive merely re-installed HAL (Hardware Abstraction Layer) and BOOM. Their problem was solved. But I still cannot mount my Windoze partition? Here is the error I'm getting when I try to mount:

Code:

Could not mount device.
The reported error was:
Error opening partition device: Permission denied
Failed to startup volume: Permission denied
Failed to mount '/dev/hda1': Permission denied

If you would like to post the contents of your /etc/fstab file we might see a clue.

Here is the information you requested....

Code:

The ",uid=knoppix,gid=knoppix" is your problem (assuming that you did not re-use "knoppix" for your HD-installed User Name).
You need to remove those strings from your fstab thus:

Code:

# /etc/fstab: filesystem table.
...
/dev/hda1 /media/hda1 ntfs noauto,users,exec,umask=000 0 0
...
/dev/sda1 /media/sda1 vfat noauto,users,exec,umask=000,shortname=winnt 0 0

AND modify your /usr/sbin/rebuildfstab file as shown here http://www.knoppix.net/forum/viewtopic.php?t=26759
to YOUR user name, otherwise it will just get reset back to knoppix user next time the system runs rebuildfstab !
Good luck

**JohnnyH** · 03-07-2007, 09:43 AM

In rebuildfstab, you don't want the $ in front of Israel, as you are now using the explicit string and not a string parameter label. So your lines should read:

Code:

  [ -n "$user" ] && options="$options,uid=Israel" 
   [ -n "$group" ] && options="$options,gid=Israel"

[Edited 09:07hrs GMT]:-
In /etc/fstab you still(or again) have the commas which are now trailing the end of umask=000 in

/dev/hda1 /media/hda1 ntfs noauto,users,exec,umask=000, 0 0

and at the end of shortname=winnt in

/dev/sda1 /media/sda1 vfat noauto,users,exec,umask=000,shortname=winnt, 0 0

(They may have got back in there as a consequence of the rebuildfstab failing on uid=$Israel and gid=$Israel)

Edit the above and see how that works - good luck

Oh, I've found out that if you edit /usr/sbin/rebuildfstab using KWrite (instead of e.g.vim) it loses its executable status.

You can test for this from the command line by

Code:

ls -l /usr/sbin/rebuildfstab

and restore executability by

Code:

chmod 0755 /usr/sbin/rebuildfstab

(or by right-click on the file in Konqueror, select Properties, Permissions, check "is executable" box).

However, it's still not obvious why your hda1 won't mount

. What method are you using to mount ?
e.g. have you tried from the command line

Code:

mount -t ntfs /dev/hda1 /media/hda1

?

e.g.are you using the desk-top icon?

e.g.are you using right-click on the device in KDiskFree ?

**Israel** · 03-08-2007, 06:23 AM

I believe I may have found the answer. I was trying to just use the desktop icon, but when I tried to use the command line I was suggested to pick a couple of options first, one of which was ntfsfix:

Code:

root@Mephistolist:/home/Israel# ntfsfix /media/hda1
Mounting volume... Error opening partition device: Is a directory
Failed to startup volume: Is a directory
FAILED
Attempting to correct errors... Error opening partition device: Is a directory
FAILED
Failed to startup volume: Is a directory
Volume is corrupt. You should run chkdsk.

I've had a problem with this and even tried running chkdsk /F from the Recovery cd to fix all that, but nothing seems to help? I guess it's just a hardware issue?

**JohnnyH** · 03-08-2007, 10:54 AM

Hmmm, I think the questions need to go further back in the whole process ... I'm not sure whether, or not, you're implying a problem with the windows partition itself...

1) Are you able to mount hda1 from the Live CD | DVD ?
1A) (and if not, was the media integrity validated OK on booting with the cheatcode knoppix testcd ?)

If 1) is OK then we can infer that the problem lies with the HD-installed Knoppix

Otherwise, are you trying to mount either:
2) a known-working Windows partition for working data transfer TO of the Linux system ? (NB if you try FROM Linux it's at possible risk to your NTFS filesystem - numerous postings on the forum refer)
or
3) a Windows partition with a problem to be rescued from Linux ?

If the answer is 2) or 3) the problem would seem to be related to the NTFS partition itself. I'm afraid I can't help much there, not having used NTFS since the days of Windows NT4, and I would not have it on a machine where I also use Linux

Oh,
4) You tried chkdsk ; if you run whichever of gparted and|or qtparted is on your Knoppix, or a GParted Live CD, does that give any more information?
