Hi there. I am unsuccessfully trying to write a data DVD on FreeBSD 4.8. The writer is a Sony DVD RW DRU-500A on IDE. I'm using the atapicam driver. The media is a Sony DVD+RW which arrived with the writer. Both with cdrecord ProDVD (from the ports or otherwise) and dvdrtools I get a general SCSI retryable error message, when trying to write a data track or blank a DVD. I have no problems writing CD-R's or CD-RW media. Any idea what the problem might be? How to work around it? Following is the output of cdrecord-ProDVD...

I have an NEC DVD-RW ND2500A (that's not the label I bought it under, but that's what it really is.) It's supposed to read/write CDs, DVDs, DVD+Rs, and DVD-Rs. I'm basically dual booting between XP and CentOS 4. Following the recipe in "The Linux Cookbook", I tried to copy a DVD using: dd if=/dev/hdd of=/tmp/diskfile.iso then cdrecord dev=/dev/hdd fs=32m

A bit off-topic. Not a question on how to get it working, but rather question about an practical issue after you get it to work ;-) I got a DVD burner that supports DVD-RAM (in addition to standard DVD+R/-R). I really liked "use it just like hard disk" properties of DVD-RAM, and according to some sources I found, the media itself is more resistant to ageing than standard DVD+R/-R.
