I have a DELL lattop (lattitude100L) with a Sony DW-R56A built in, actually it's listed as:- "SonyDVD+RWDW-56A" and it will not Burn a DVD. Checking deeper on the computer, it's a CD-ROM.
I have in the same unit a CD Player/Burner, and asked for a DVD Player/Burner. Dell insists that this will do it, if so, how do I find the Burner? Slip a CD in,up pops the PLAYER/BURNER asking what I want to do, slip a DVD in and it brings up the player (WinDVD) and starts playing. But I want to be able to BURN my own DVD's!!
Any HELP ?????

Got this as a replacement in my Dell so better than the last drive. Worked fine in datawrite 2.4, but not on my bulqpaq / bigpockets - these both appear to be the same IS01-001-000 Info Smart Technology but tried a few with different software and no results

This piece of hardware runs ok on 4-speed disks. However it is made to burn on 8-speed and that is the only problem I am running into. Based on the current firmware (QDS1) it doesn't even burns 8-speed RITEK R03 DVD's.
Both Dell and Sony don't have a suitable firmware upgrade. It is a shame. Don't buy it !
