I’m using a DELL Latitude D810 with a DVD Burner.
I installed a FC4 (full installation), and I upgraded it using yum. So
I’m running 2.6.12-1.1398-FC4
My DVD Burner is a NEC DVD+-RW ND-6500A.
By doing this test:
Copy a 2Gb file from the DVD to the harddisk.
On windows: 4minutes 3 seconds
On linux: 27 minutes.
hdparm –I /dev/hdc tells me that DMA isn’t activated…
hdparm –d 1 /dev/hdc tells me that I’m not allowed to activate DMA on
the DVD burner…
Why ?
How to bring my DVD to work on linux as on windows ?
Michel,
try running lspci and see what IDE interface you're using/
I'd guess that it's Intel 82801FBM controller.
You might want to CC yourself in on this bug:

I suspect that this is going to affect a whole load of new laptop users
as it seems quite a few laptops are using the Intel chipset in question.
