Need help in finding what DVD burner is in this computer

A friend of mine gets HP’s and Compaq’s about 1/2 off there price where he works and he is deciding between Compaq Presario SR1250NX and a HP A620N.

He will be giving me the DVD Burner from either of these machines. I have googled all morning and even emailed HP as to what brand burner is in these systems and have not gotten a reply yet.

It seems the Compaq’s is a dual layer drive.

Anyone know what drives would be in these systems?


Unless the systems are directly assembled by HP and then sent to the markets for being sold “as-is”, they are customized and you cannot know what drives are installed unless you ask the dealer.
