I'm currently having a weird problem writing 2 files to a CD-RW disc. One thing I'd like to try though is writing the disc at a slower speed. The trouble is, though I'm saying:
mkisofs -V 0.1.05 -r . | cdrecord -v -eject speed=2 fs=6m dev=0,0,0 - the output from cdrecord shows that it's actually writing it at 4x speed! Behold: Starting to write CD/DVD at speed 4 in write mode for single session. Does anyone know how to override this? Actually, it would also be nice to try writing at a faster speed too. The drive is capable of 10x for CD-RW, but I tried speed=10, and removing the cdrecord config files, and couldn't get it to write at anything except 4x. Any advice would be welcome. (Output is below.) (The weird part is that I can write other files, bigger or smaller, onto the same set of CD-RW discs; I just can't write these particular 2 files. But I want to try the other speed writes before I get too flummoxed by that particular bit of weirdness.) luke mkisofs -V 0.1.05 -r . | cdrecord -v -eject speed=2 fs=6m dev=0,0,0 - Cdrecord 1.9 (i686-pc-linux-gnu) Copyright (C) 1995-2000 J�rg Schilling TOC Type: 1 = CD-ROM scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.22 Using libscg version 'schily-0.1' atapi: 1 Device type : Removable CD-ROM Version : 0 Response Format: 2 Capabilities : Vendor_info : 'SONY ' Identifikation : 'CD-RW CRX175E ' Revision : '1.0j' Device seems to be: Generic mmc CD-RW.
