Hi,
DELL put in LG cdroms and Burners, i have the 8080 Burner in my DELL pc at work and it works with CLONE CD with no problems, so im sure you wont have a problem either, although i think they are stocking 24x or even 32x speed burners in there pcs now.
remember if you download a crack for FULL access to CLONE CD you will just burn coasters, so make the most of the 30 day trial at full speed and then purchase an unlock key, its well worth it and it does not cost that much.
Been using CLONE CD for a couple of years now and its never let me down.
Cheers
Dal
