Hello
I recently purchased two new DVD burners. Neither of this DVD drive were able to read some DVD R that I burned with my older DVD burner. I am able to read the disk with a windows computer so I do not think there is a problem with the DVD media.
I experienced the same problem with both of the DVD burners. I cannot read the first 271 MB of a disk and then will report an Input/output error for the remaining data.
Have manufactures moved the error handling from the DVD burner to the Windows driver? Did I purchash two bad DVD burners? The first of DVD burner was a Memorex and my current burner is a Plextor PX-L890SA.

Hello The problem has been resolved. I turned of the auto configuration for the CD ROM drive in the BIOS. This was configuring the PIO to 2. I manually set the the PIO to 1 and then I also setting this to 0. I left the DMA setting the same as the autoconfiguration which was UDMA5. After these changes I was able to read the disk that were not working and the drive appears to be responding faster. Motherboard: ASUS P5B-Deluxe CD ROM Drive: Plextor PX-L890SA (This is an SATA Drive) I have not been able to confirm the drive is operating in a DMA mode the hdparm reports an error. # hdparm -d /dev/sr0 /dev/sr0: HDIO_GET_DMA failed: Inappropriate ioctl for device I am not sure if the SATA is treated as a SCSI or IDE. The man page for the hdparm clams: "...provides a command line interface to various kernel interfaces supported by the Linux SATA/PATA/SAS "libata" subsystem and the older IDE driver subsystem" I was unable to find any of the ata parmeters with the sysctl command. .... It works, at least it reads. Aaron -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
