</div></div>I guess you're trying to get at the disks from the old Ubuntu install<br>
that broke?<br>
<br></blockquote><div>Yes.<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
The 'not authorised' bit would be because the livecd user you're logged<br>
in as on the live cd isn't the same user as you were on the installed<br>
system.<br>
<br></blockquote><div>That's what I guessed. I think it is terrible usability. One example: once a friend of mine reinstalled Ubuntu, and wasn't able to access his external hard disk afterwards, because he wasn't considered the owner of the disk anymore. That was a very embarassing situation for me, as I was the one who recommended Ubuntu for him as an easy to use operating system. My friend shook his head when I told him that this is considered a feature, not a bug. I have faced the same situation several times, and it's always annoying, as there doesn't seem to be any simple, repeatable way to get out of it.<br>

What was the chown command that you ran, and did it itself produce any<br>
errors?<br></blockquote><div><br>No errors. The command was "sudo chown -R user:user /path/to/the/folder<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Generally, when you're taking backups, the solution to the<br>
access problem is to run the backup as root, rather than chown the<br>
files </blockquote><div><br>Thanks for the suggestion, I'll try to remember it the next time (although it doesn't sound something one should have to do on a user friendly distro). Does this mean, that the backups that one has made with a regular backup program are not usable when a reinstall is being done? In a wider context, why not make the permissions settable (is that a word?) from the file manager, as they already are in a crippled way (I know, it's a featrue request (bug report) that doesn't help me now).<br>
</div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">- presumably you'd prefer to take the backup of the files<br>
preserving their permissions.<br>

Doesn't this conflict with your suggestion to take the backups as root? (Perhaps I don't understand, what "preserving their permissions" mean or how do I do that).<br>
