slow read rates with sony drive

i have a sony dvd+-rw dw-q58a in a m140

when i try to rip a dvd i can only achieve a read rate of x 1.1 why is it that it is going so slow? i can get at least a read rate of x 4.0 on my desktop.

also i was loading some movies that i had burn to a dvd cd the file size was 3.6gb and by just dragging and droping the file into the folder i wanted it said that it would take 45 min to complete. **** me old ass dvd drive on my desktop goes faster than that, i even tested it and it was 15 min so somethink is wrong. i got a 250gb externial hd and i can transfer 17gb from a usb 2.0 cable to it in about 20 min.

something is wrong, its got to be

well the power options are on desktop/home and the ac line is pluged in so i think that the power settings should be at there highest.

ok well ill try that but i also was loading some movies that i had burn to a dvd cd the file size was 3.6gb and by just dragging and droping the file into the folder i wanted it said that it would take 45 min to complete. **** me old ass dvd drive on my desktop goes faster than that, i even tested it and it was 15 min so somethink is wrong. i got a 250gb external hd and i can transfer 17gb from a usb 2.0 cable to it in about 20 min.

ok i have done some more testing and i have a 16x sony dvd external drive that is hooked up to my computer by a usb 2.0 cable. i can rip a dvd and get read rates of up to 6.0x. now i understand that the external drive has a faster read rate but why is it that i can read data quicker through a usb 2.0 cable than i can on my internal dvd drive, doesnt that seem odd. also when it comes to cpu usage im maxing out the 1.73 p-m when just riping a dvd (not encoding but JUST ripping the data off it) on the interanl drive and when i use the external drive im hovering at about 10-25% cpu usage and it doesnt even clock up to 1.73, it says at 800 mhz.

when using the external dvd drive and ripping a dvd i can also run media player, firefox, encode a dvd, and my ram usage only goes up to 410mb and everything run smooth and doesnt lockup. howerver if i use the internal dvd player to rip a dvd and that is it the systme lags and is not that responsive.

i have already uninstalled the dvd drives and reinstalled them and that did nothing.

i have used nero to find out what the bust rate is on the transfer and i am only getting 2mb/s that is VERY low and should be much higher, again what give? on my external drive i can get 21mb/s and thats through a usb cable.

i only have 512 ram(256x2) could that be a reason for the slow read rates? is so them why is it then that the external goes faster though?

no thoughts anyone
