Hi Could someone please help me with cdrecord? I cannot blank a CD-RW disk. See the cdrecord input and output below. I've logged in as root, cdrom wasn't mounted. The computer is Dell GX100 (500 MHz, Pentium II), with HP CD-writer+ 8100. The o.s. is Fedora Core 1. The CD-RW's I tried are of good quality and a Windows machine was able to blank them. Writing a CD-R/CD-RW works ok. Cheers, Kari [root@voitto kari]# cdrecord -blank=all -dev=0,0,0 Cdrecord-Clone 2.01a19 (i686-redhat-linux-gnu) Copyright (C) 1995-2003 J?rg Schilling scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.25 Using libscg version 'schily-0.7' cdrecord: Warning: using inofficial libscg transport code version (schily - Red Hat-scsi-linux-sg.c-1.75-RH '@(#)scsi-linux-sg.c 1.75 02/10/21 Copyright 1997 J.
