Using Knoppix to rescre data from a non-boot hard drive

[satimis]

Hi folks,

This is my first time using Knoppix CD to rescue data from a non-boot Hard Drive.

The HD was running FedoraCore3 unable to boot because of using non-compatible repositories download/upgrade non compatible packages.

Hard Drive - 3 partitions
/boot
/home
/swap

I expect to save and copy some data/files from /home/user/ and burn them directly on CD, not to backup all of them.

Using following command line on Konsole/terminal

# mkisofs -R -joliet-long -graft-points -hide-rr-moved \
/name-A/=/path/to/dir-A/ \
/nanm-B/=/path/to/dir-B/ \
/name-C/=/path/to/dir-C/ |\
cdrecord dev=ATA:1,0,0 -v -eject -

I can burt directory/subdirectory/files directly on CD without creating ISO image. It works for me on Fedora, Debian, etc.

Does Knoppix include "mkisofs" and "cdrecord"?

Can the forgoing command work on Knoppix environment?

If NO please advise other alternative on Knoppix

TIA

Try using k3b in Knoppix to put your files on the cd.

Hi budman7,

Tks for your advice.

I haven't used k3b before.

Whether the instruction on following link applies;
http://www.eleli.de/knoppix/docs/tut...glish/k3b.html

Whether it is the same as "Direct CD" on M$Windows using "Drag and Drop" method to copy/move files to CD, treating the latter as Hard Drive.

Please advise. TIA

I haven't ever used Direct CD before. So, i don't know how it works.
But, you can drag-n-drop with K3b.
Yes, those are the directions for k3b.

Hi budman7,

Noted with thanks

A further question, if the files are burnt on CD-RW can I use K3b to move/delete them? That is the feature of Direct CD. You can copy/move/delete files from CD-RW with Drag-n-Drop method

I have never tried to delete single files on a cd with K3b.
I have just used it for backups and erasing cd-rw's.

But, you could try it, K3b is probably the best cd/dvd burning software out there.

Hi budman7,

I have never tried to delete single files on a cd with K3b......

I tested K3b running on a FedoraCore2 box here. It allowed "burn on fly". Its feature is more or less similar to "cdroaster" (or some thing like that), the GUI/front-end of cdrecord. I used it about 2-3 years ago before I turned back to command line because I found the later more convenient to me.

K3b doesn't have the feature of Direct-CD (Easy CD creator), which has different file system, running on M$Windows. It allows "drag_n_drop" files direct to/from CD-RW on home browser (Konqueror) without starting the software. What you need to do is just format the CD-RW to UDF format. So you can use CD-RW as a mobile HD bringing it between home and office. I used Direct-CD above 5 years ago before turning to Linux/FreeBSD. Since then I started searching its equivalent on Open Source. There was a project started heading on this file system but I stopped followup sometimes ago. I have no idea of its latest development.

One thing I can't resolved. I could not burn Knoppix ISO image on CD-RW, always complaining insufficient capacity, since I first used Knoppix several years ago when it first came to birth. I did try to burn it on CD-RW with bigger capacity but still failed. I don't understand the cause.

I'll burn the Knoppix ISO image on CD-R later. What project shall I select to burn the image on CD-R so that the CD-R will work as Live-CD not copying the image file to CD-R. Data project? What other parameters to be selected.

Tks

Hi Hi budman7,

I got the working data on the non-boot FedoraCore3 box burnt on CD. However I encountered problme on login as root to work K3b.

During booting Knoppix I can't login as Root only as User.

K(Knoppix)Start -> Multimedia -> K3b
started K3b as User and I was not allowed to browse the HD ( hda1, hda2 and hda5)

Therefore I have to start K3b from Konsole after login as Root
$ su
# k3b

Any advice, how to boot Knoppix as Root. TIA

[budman7]

That is weird, whenever I use Knoppix, I just login as root at the login screen.
root for user name
root for passwd

If I remember right.

Hi budman7,

I'm replying your posting on Knoppix 3.8.2

Still I could not start Knoppix as Root during booting

boot: root username [Enter]
Could not find kernel image: root

boot: root [Enter]
Could not find kernel image: root

I must hit ENTER
boot [Enter]

Knoppix started as User

Bringing up Konsole
knoppix@1[knoppix]$

knoppix@1[knoppix]$ su [Enter]
root@1[knoppix]#


F2 and F3 instruction at boot did not help.

I'm still looking around how to boot as "Root"
