[mdlug] Unable to mount a dvd on a drive which was used to write it.

[R KANNAN]

Hi,

Thanks for the help. Please see my comments below.

I found that I could mount other DVDs on the 'bad' drive (which have
been burnt using the 'good' drive)  as root.

The only problem I seem to have is to mount a DVD that has been burnt
on the same drive as 'user'

I am not sure what you mean by close the disk. You mean close 'k3b'. I
am not burning a multi-session DVD.

Seems to be but note that I can mount the DVDs burnt on this 'bad'
drive on the 'good' drive fine.

No I did not in this case. I can try doing it.
