I've recently bought a Packard Bell Easynote laptop. It comes with a "_NEC DVD+/-RW ND-6500A" DVD/CD ReWriter. The machine used to have XP on it, it now has Gentoo 2004.q4 and I'm running the Gentoo-patched 2.6.9 kernel. IDE-SCSI is not enabled. If I attempt to burn a DVD+R using either K3B, or doing by hand using growisofs, the burning appears to work properly - no errors are printed, I get no buffer underruns. However, when I come to mount the DVD again I get the following error: attempt to access beyond end of device hdc: rw=0, want=68, limit=4 isofs_fill_super: bread failed, dev=hdc, iso_blknum=16, block=16 After having a google around the web, I installed kernel 2.4.26, enabled IDE-SCSI and tried again. Again the burning seemed to work OK, but I can't mount the DVD, it gives the same error. I even made an ISO image on my HDD first, and mounted that using the loopback device just to see if the data I was writing to the DVD was correct. The ISO image mounted properly. Before I wiped XP from this machine, I made a test DVD+R. I can mount this OK. What's confusing me quite a lot is that if I put the DVD into my DVD-video player it reads it OK... I currently don't have any other PCs with DVD-ROM drives to test the disks in, but it's not so good if I can't read them in this machine. Curiously enough, if I attempt to 'dd' the contents of the DVD back to my hard drive, it reads 4k and then stops - no matter what settings I give dd. If I put in the working DVD I burnt, it reads the whole thing OK. The disks have all been burnt as single-session DVD+Rs with either Joliet+RockRidge, or UDF. Any ideas about what might be going wrong? This machine contains an Intel mobile P4 CPU, so is running an SMP kernel. -- http://www.piku.org.uk - Outdoor Photos: http://www.piku.co.uk - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
