|
|
I have a problem with my SATA CD/DVD writer Plextor PX-755SA.
Everything is fine as far as I burn only CDs - write speed goes to 48x without any problems.
But when I want to write a DVD (DVD-R(W), DVD+R(W) - it doesn't matter), the write speed NEVER gets above 1x. I use K3b (growisofs) for DVD writing.
Example:
Code: | # growisofs -speed=6 -Z /dev/sr0=/dev/zero
WARNING: /dev/sr0 already carries isofs!
About to execute 'builtin_dd if=/dev/zero of=/dev/sr0 obs=32k seek=0'
/dev/sr0: "Quick Grow" session...
/dev/sr0: "Current Write Speed" is 6.1x1352KBps.
