Count mount drive after failed upgrade (solved)

[mpstump]

Hi, after an unsuccessful upgrade, I installed Kubuntu Intrepid on another drive on my system. The other drive has the old data before the bad install. I had a grup error (error 16 I think), so I just installed kubuntu intrepd on another drive (sdb) . I'm trying to get the data off the 1st drive (sda), but I can't mount the drive. Here's my sudo fdisk -l output

mpstump@maisie-desktop:~$ sudo fdisk -l
[sudo] password for mpstump:

Here's what happens when I try to mount sda1...

mpstump@maisie-desktop:~$ sudo mount /dev/sda1 /mnt/old
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

mpstump@maisie-desktop:~$

“sudo mount -t ext3 /dev/sda1 /mnt/old “ produces same result as above.

Here's what testdisk tells me...

sudo testdisk

So where do I go from here? Testdisk sees my data so it should be easy to copy, but how do I get to it? I think I'm missing something with Testdisk. How do I restore data with it?

Re: Count mount drive after failed upgrade

Have you attempted to check the filesystem on the drive?

sudo fsck /dev/sda1

[mpstump]

Re: Count mount drive after failed upgrade

This is the ouput of sudo fsck /dev/sda1

mpstump@maisie-desktop:~$ sudo fsck /dev/sda1
[sudo] password for mpstump:
fsck 1.41.3 (12-Oct-2008)
e2fsck 1.41.3 (12-Oct-2008)
fsck.ext3: Device or resource busy while trying to open /dev/sda1
Filesystem mounted or opened exclusively by another program?

Should I try to install a file system? How do I do that? I think it should have ext3.

modified...

I don't know why it's giving me that error message. Nothing is mounted to that drive. In dolphin, it shows up under "places" as volume(ext3), but when I click on it, nothing happens.

Re: Count mount drive after failed upgrade

Is /dev/sda1 identified in your current /etc/fstab file? If it is, then I'd attempt two things:

1) try unmounting the devise: sudo umount /dev/sda1 and then running sudo fsck /dev/sda1
If that doesn't work, then
2) edit /etc/fstab (as root) and comment out the entry (put a # space in front of the line), save, and reboot the system. This ensures that the drive isn't mounted. Then run sudo fsck /dev/sda1

Re: Count mount drive after failed upgrade

It's says it's not mounted

mpstump@maisie-desktop:~$ sudo umount /dev/sda1
[sudo] password for mpstump:
umount: /dev/sda1: not mounted

I've even booted from the kubuntu live cd, and tried to mount, with the same result.

my fstab

Re: Count mount drive after failed upgrade

Do you have a Knoppix LiveCD you can boot from? If not, download from here. Every Linux user should have this in their toolkit. See if you can access the drive from Knoppix.

[mpstump]

Re: Count mount drive after failed upgrade

Nope, Knoppix basically gave me the same thing. Knoppix labeled the drive hda1, otherwise, the same. Could this be as simple as a permission thing? I'm thinking it's something bonehead like that, which I'm overlooking. I tried "sudo chmod 777 /dev/sda1" , it didn't give me an error, but it still won't mount either.

I do like the Knoppix distro, though.

Re: Count mount drive after failed upgrade

So, I think I have a solution by using either dd or testdisk. The problem I ran across is my current drive isn't big enough to backup the whole thing. So, one Bestbuy trip and a Maxtor usb drive later, I'm almost ready to give it a try. The big questions now are a) should I keep the usb drive as a ntfs drive, or reformat, and b) how do I turn the *.dd file back into the directory structure it once was. When I figure this out I'll repost, unless anybody has some advice now.

Thanks,

Matt

Re: Count mount drive after failed upgrade

Well, I went down the wrong path a few times, but I finally got it.&#160;

I was able to make a complete backup to work with on my newly acquired usb drive using testdisk, as opposed to monkeying around with the original, with the threat of mass data loss.

Then I tried photorec, which gave me all of my files, with no directory structure, missing filenames, etc. That wasn't going to do me a lot of good either.

Finally I used fsck to restore the filesystem on that backup (pretty neat).&#160;

sudo fsck /path to backup image.../image.dd

...image.dd is the name of the newly created backup file...There were a lot more problems with this disk than I thought. After hitting y for yes about a million times, the directory was restored, and the files recovered by using mount like this

sudo mount -o loop -t ext2 image.dd /mnt/rec

where image.dd again was the backup image, and /mnt/rec was a new mount point.&#160; Life is good again.

Outstanding! Very good. Please return to your initial post in this thread and click on the modify button and put SOLVED in the subject line.
