There are several -reasons for changing the speed of a CDROM drive. Badly pressed CDROMs may -benefit from less-than-maximum head rate. Modern CDROM drives can obtain very -high head rates (up to 24-times is common). It has been reported that these -drives can make reading errors at these high speeds, reducing the speed can -prevent data loss in these circumstances. Finally, some of these drives can -make an annoyingly loud noise, which a lower speed may reduce. - -Howto -~~~~~ -The recommended way to do it is with a program called 'setcd' . It's kinda -old, but won't be too hard to find on the Net. -Use it with : - setcd -x <speed> <cdrom device> - -Also you can try : - echo current_speed:4 >/proc/ide/<cdrom device>/settings -but you'll need root privileges. (It didn't work for me - Gabucino) - -I use following command too : - echo file_readahead:2000000 >/proc/ide/<cdrom device>/settings -for 2MB prefetched reading from the file (it's useful for scratched CDROMs). - -It's recommended that you tuneup your CDROM drive also with hdparm : - hdparm -d1 -a8 -u1 <cdrom device> -to enable using DMA access, readahead, and IRQ unmasking. -(if you don't understand these, *read the hdparm manpage*) - -Final words -~~~~~~~~~~~ -Please refer to "/proc/ide/<cdrom device>/settings" for fine-tuning your CDROM. - - Nick Kurshev & Gabucino - <nickols_k@mail.ru> - - |
