Reading/copying /home with a live CD

danorske · #1 (**permalink**) 07-Nov-2009, 15:19

HI,
I have a messed up HHD with OS11.0 on it. I'm unable to boot it or load it. If I use suse 10 live it sees only itself. If I use Knoppix live I can see /home on the drive but I'm unable to copy any of the files. cause I don't have permission. How can I log in as SU? to get the permission that I need.

Thanks,
Ron

That rather depends on how knoppix works, but I'd guess it doesn't have a root password (most Live CD's don't. If it does, try to guess it or google it).

Load knoppix

Code:

su -
[password here]
fdisk -l
mount

That should tell you which partitions are on the system, and which are mounted. If it's already mounted, great! Rescue the stuff you need. If not...

Code:

mkdir /mnt/suse
mount /dev/sdXY /mnt/suse
cd /mnt/suse
[rescue your stuff]

Substituting sdXY for the correct information from before. If you get the wrong partition, just

Code:

umount /mnt/suse

and try again...

Thanks Confuseling,

I am able to use Terminal as su. no password needed. My Linux command language is really limited. If I have a file on the old /home/pictures and want to copy it from hdb3 to uda1. what is the copy command?
I followed your instructions to cd /mnt/suse

From there I'm kinda lost.

I can usually manage this in knoppix once the partition is mounted, if you are just copying it should just work.
Other than that I use Mepis which has a root login on the live cd, also Parted Magic IIRC can manage this. Of course a suse live cd can be booted as root but I have never tried it's capabilities.

I've lost my Suse live disk. How do you spell copy in linux?

eg:

Code:

cp /dev/sda1/foldername* /dev/sdc/backup*

Replace with your values/foldernames etc...

You had any luck? I'm a little confused by you mentioning hdb4 - I didn't think SUSE 11 designated anything 'hd', but I may be completely wrong.

If you're stuck, give us the output of 'fdisk -l' from your knoppix root terminal, and tell us which partition you're trying to copy parts of to which other partition, and we can give you precisely the right commands...

Well, I got unstuck, I installed OS 11.2 on a new HHD. Then out the bad hhd in as a slave and was able to rescue my files.
Oh, Knoppix live 3.8 labeled that drive as hdb4.

Thanks for all your help.

Doh! clearly not paying attention, sorry about that...

Glad you're sorted though...
