DVD drive not recognised

[dapeba]

Hi - Thanks for the response. The Sony DVD drive is not shown under drives and inserting a film/music DVD has no effect, but the drive is OK as I can insert the installation disc and run it on the laptop. At one time I did get a message 'Can't mount file' relating to the DVD drive, which is why I mentioned the term 'mounted'. Apologies for not being more specific, I'm feeling my way with LL. - Regards
