So right now I have installed k3b on this notebook. I am using my Storix DVD/CDRW usb drive. I can read cds with it.
Cannot burn CDs. First k3b suggests slowing down (from 8x to 4x). Then use TAO. Then it gave up.
So I try cdrecord directly. -checkdrive finds some interesting things. Got to close the drive manually; cdrecord says it can't. then try a cdrecord -v dev=dev/scd0 sample.iso and if fails:
cdrecord: No write mode specified. cdrecord: Asuming -tao mode. cdrecord: Future versions of cdrecord may have different drive dependent defaults. cdrecord: Continuing in 5 seconds...

So what of this?
These are Memorex 700Mb/80min CD-R disks. Bought them probably 4 years ago. Got about 200 of them and down to about 30.
