[olug] RE: error w/ cdrdao

[Sam Tetherow]

Guess I just have wonderful luck with my burning.  I buy cheap disk 
(e-works/khypermedia) for .04/disc and put them in my elcheapo ide 
burner (some no name I got for $20 after rebates at Office Max).  I 
occasionally get failed burns but no more than 5% failure rating and I 
usually get about 1000 disks out of a burner before that rate starts to 
go up.  When this occurs I wait for the next elcheapo drive to get down 
to the $20 range after rebates and pick a new one up.  I've been through 
3 burns in the past 2 years and over 2000 discs and have only spent 
~$100 on burners and average about 5 to 7 cents / disc.

The only thing I have found burning under linux is I can't manage to get 
any speed between 24 and 48 (just defaults back down to 24x) and a lot 
of the bargin media is 32X-40X which means I end up burning at 24X yet 
under Win2k I can burn at 32 and 40 without a hitch.
