This actually fails on several counts: > Okay, say I have a drive that isn't working. What sort of stuff should I send? I can send the exact model and manufacturer, and the output from dmesg after a -v boot. I'm guessing that this isn't enough.. Are there tools out there for looking at CDROMs? Or do I use gdb to step through the code? In the latter case, I suppose I'll have to learn how to do this :-) I was planning on learning the FreeBSD/Unix procedure for developing and debugging device drivers over Christmas -- this ATAPI thing should motivate me enough to switch from my normal "user" mode to a somewhat more helpful "developer" mode. Also, this brings up the more general question of: What do I need to know to be a good "tester". I'm guessing being a master of gdb is step one; what features of gdb should I be focusing on? -Mark P.S. - I'm trying to squeeze as much into my head as I can, but I fear my rate of comprehension isn't fast enough to be terribly useful in the near future. I've only been C programming and using Unix for about a year - I was encouraged yesterday, however, when I was able to successfully modify the lpt code to query the parallel port to determine if it was bi-directional! I'll figure this stuff out some day :-) > > Thanks! > Jordan > --------------------------------------------------- | Mark Mayo mark@quickweb.com | | RingZero Comp. vinyl.quickweb.com/mark | --------------------------------------------------- "To iterate is human, to recurse divine." - L.
