Boot with CD -> can't write to existing ext3 HD-partition

[leoneill]

Hi,

When I use the Knoppix-CD to boot the PC, the hda en hdb drives (with an existing Redhat install on it, ext3) are mounted OK by Knoppix. I can read them.
But when I want to write to these drives, I get an 'no permission to write' error.
Can someone plz help me out with this?

tnx, Eric

Right click on icon ->Properties->Permittions-> (Make neccessary changes) -> Advanced Permittions-> (Make neccessary changes) ->OK->OK

The idea behind: everything is read only by default

RT click on icon, select 'actions', select 'change read/write mode'.

Hmm, OK tried that, still not able to write on them.
Maybe it is something to do with the rwxr-xr-x settings, eg. knoppix is considered not the owner?
