Running "dd if=/dev/dvd of=/dev/null" on a burned disc reports read error at or around the block where the speed jumps from 2.4x> 4.0x or from 4.0x> 6.0x. I had logs for this, but misplaced them =/. Also when jumping to the next higher speed there is a dip where growisofs reports 0x burn speed, is that normal? > -- > Len Sorensen _________________________________________________________________ Hitta bästa priserna på MSN Shopping! http://shopping.msn.se/co_16199-msn-shopping.html
