Hello

I have NEC ND 4551A with original firmware

I try to decrease a speed my DVD drive NEC ND-4551A , because there's a noise during play of DVD disk.

I type in Linux

# hdparm -q -E1 /dev/dvd
#setting cdrom speed to 1

but nothing happens - the speed doesn't change.

is it possible to make it - to decrease speed of my dvd drive ?
in what way can I see in Linux real speed my dvd drive ?

So, If you don't know Linux, please answer - is it possible to lock the speed DVD drive in Windows , does the drive support that possibility ?
