Hello, I have a problem with -E command. I use it to set speed for my dvd drive, but it doesn't work. I found http://noto.de/speed/speedcontrol.c and it's works! I als found that dvdspeed.c in hdparm-9.15 is very similar to speedcontrol.c, but there are some differences. I think that these differences are source of my problem.
Add corresponding bug #2822532
Ok, it works now in hdparm-9.19. Thanks! (BTW, can't comment in bug #2822532. SF says that I need to login to post a comment. But I'm logged now :)
