knoppix as a rescue disk

lynnevan · 08-23-2006, 05:05 AM

I've read from several sources that people like to use Knoppix as a rescue disk. I like Knoppix a 'lot'. Fast & up2date on all the hardware and generally easy to use. What I don't understand is how? When I use it, everything on both harddrives is read only. How can it be used to fix something you can't change?
Thanks forever if you can answere this one!

I hope you have installed Knoppix on your hdd. If not, you wont be able to write anything anywhere.
you mostly use it to recover data and not write data on the windows drives. 1)supposing you lost your windows pass, you cant login, you boot with the cd and copy the sam file to try and recover your pass. 2)suppose your system isnt booting properly copy the imp. stuff on your linux system and more

It's used when the system on the hard drive won't boot. You have to have some inkling of what is wrong. Then Knoppix is used to boot the computer and fix the installed system. Many problems are corrected by editing a configuration file or two. Once you've booted with Knoppix, you can edit those files. Or if you don't know what to do, you can boot with Knoppix and go to LinuxQuestions.org to start researching!

Knoppix mounts drives read-only when you use the GUI. The command line has no such restrictions: "sudo su" gets you a root shell, and then just mount the drive you want, and you have full read-write access.

It's a simple way to keep your drives safe when you're an inexperienced user playing around, but letting you do what you need to when you're an experienced user with problems to solve.

This is done deliberately so you can't accidently damage your system. As mentioned, simply remount partitions as r/w if you need to update them.
Knoppix is great for this - I always keep a disk handy.
