I have a Dell Inspiron 6400 with a NEC 6650A dvd drive. Lately I have noticed that I am getting slow burn and read speeds, about 0.9x for each (I usually use ImgBurn but get the same results in Sonic - the app that came with the Dell). It also takes ages copying data files from dvd to hd.
I used to get good speeds, the big changes that have happened are installation of Office 2007 as well as usual OS (XP Pro) and McAfee updates. Most other apps etc are the same.
I have not flashed the drive or done any other mucking about. I have checked in device manager and as far as I can tell it is using dma already.
Thanks in advance.
