Knoppix, how can I get data off it?

[stytagm]

I've been using knoppix a bit lately on both my own comp and my parents and have come up with the following problem, how the hell do I get data off it, specifically by burning a CD?

Knoppix doesn't let you write to the local disks, presumably for security / safety, and while it offered to make a permanent knoppix home directory I assumed that windose wouldn't be able to read it, so I didn't bother.

The first few times I was at home and so I emailed things to myself, but when I was at my folks last week that wasn't an option (nasty dialup), so I spent an hour looking through man pages for CDRecord and getting nowhere. I can use a command line, Just, in Linux so this was a little beyond me. I only wanted to write one or two files to a disk.

So, anyone got an easy guide to using CDrecord, or an alternative?

ok - here we go.

on live CD's you can write to certain areas which are contained in RAM. eg: /var/tmp

put your data in a dir in /var/tmp

then use mkisofs to create an iso image of your data dir

mkisofs -o /var/tmp/myiso.iso /var/tmp/data_dir

then use cdrecord -scanbus

you'll get a load of info like this

0,0,0
0,0,1
0,0,2
0,0,3 SOME CD BURNING DEVICE

the 0,0,0 represent the position of the device on the bus, and your probably using an IDE burner so that will mean your using SCSI emulation to burn this

"SOME CD BURNING DEVICE" represents the name of your device such as "Sony CD Writer"

Now use

cdrecord dev=0,0,3 -speed 8 myiso.iso

this will burn the data from myiso.iso onto the burner at 0,0,3 at 8 speed

You may need to check the syntax of these commands as I'm on my laptop with no writer at the moment, but you'll be ok with that basis.

or use k3b, if it's supplied, it's a decent easy cd creator clone

Surely if something was to be a clone of Easy CD Creator, it would have to be buggy, slow, create lots of useless cd-shaped coasters and be generally the crappiest piece of software ever?

Whereas K3B is actually quite good.

Thanks for the info guys, I'll let you know how I get on.

You can write to the hard disc by remounting it as read/write.

Once you have found out which partion you want to write to, type into a console window:

sudo mount /dev/hda5 /mnt/hda5 -o remount,rw

where 'hda5' is the partion you want to write to.

The sang is, that will not work with NTFS partions, so if you are using XP, then you are probably out of luck.

[directhex]

the above assumes

1) you already have an empty folder called /mnt/hda5
2) the disk is already mounted read-only in this location (hence the -o remount to change an existing mount)

whether these apply by default on knoppix, no idea

people who use knoppix are 9 times out of 10 booting linux on a windows box.

this means chances there will be no partitions defined other than a windows partition which is NTFS and therefore not wirte supported in knoppix
