My first and, until now, only DVD-Writer died yesterday. It was purchased new in April 2005. I burned many hundreds of DVD-Rs with it. It will be missed. It was an IDE DVD-Writer with Molex power connector. I have replaced it with a low-cost Lite-On 24x Writer with SATA power and SATA data connectors. The first thing I noticed about it is how it burns a 4.2GB DVD-R in 10 minutes as opposed to 6 minutes like my previous IDE burner. Also, when I simply copy a 4.2GB DVD to my internal hard drive, it initially says the copy process will require some 36-40 minutes to complete! The initial speed is 1.9MB/s. Curiously, however, after a few minutes the speed gradually increases to the same 5.9MB/s I was accustomed to with my previous drive.
My first guess is that DMA was not "on" for this drive - but after extensive Googling for info, there seems to be a consensus that DMA is only useful with IDE drives. It appears that many people have had problems with slow SATA drives and Linux during the past 3 years - but solutions are proving elusive.
What can I do to bring this new SATA drive up to par with the performance with which I have grown accustomed over the past (nearly) 5 years?
I am a generally elated Linux Mint 7 user, btw.
