Description Sherwood 2010-05-09 21:48:18 UTC
Version:           1.91.0 (using 4.4.3 (KDE 4.4.3), PCLinuxOS release 2010 (PCLinuxOS) for i586)
Compiler:          gcc
OS:                Linux (i686) release 2.6.32.11-pclos2.bfs

Several days ago, prior to installing new pclos 2010 release, I used K3b (in pclos 2009) to back up all the data I wanted to keep (mp3s, jpeg, bmp, avi, mpeg, pdf, the usuall etc)
to DVD+R in ISO format. When I was done, I made sure they were accessible before continuing with new OS install. Now, after I'm up and running, the DVD-RW used to make them is unable to
mount any of the data DVDs with the command line -- mount -t iso9660 /dev/sr0 /media/cdrom, and K3b informed me that the background data was incomplete and that the disc (and I quote)
"was probably created with buggy software". I can't decide whether to laugh or cry. Also, up until today, I had been able to mount the discs in my other drive (which is a DVD-ROM)
but in read-only mode which was annoying because I had to then right click and open files as root, put in password, etc. and it was only about 50% successfull in copy/paste operation.
K3b recognizes the disc in both DVD-RW and DVD-ROM drive, but only reports ISO info in DVD-ROM. I right clicked and selected copy medium in both drives, only checked "only create image" to 
try to copy entire ISO back to hard drive and both times it err.

Here is debugging output for DVD-RW

 I then tried enabling DMA on both drives using hdparm (in super user mode) and both drives said "setting using_dma to 1 (on)
HDIO_SET_DMA failed: Inappropriate ioctl for device HDIO_GET_DMA failed: Inappropriate ioctl for device". Call me crazy, but I hope all this babbling I've just done is a waste of your time
and mine due to something simple I've been overlooking. Please let me know if you require any further info, if this is even truly a bug with K3b. Thank you for your time. 
Sincerely, still a complete noob.
