WOW! Amazing. I guess that's good to hear. Hmm...maybe that
explains why I always see the problems towards the beginning of the
tape. I guess the windows software also sees the same errors, but is
more tolerant of them and tries harder? But if that's the case, the
linux driver shouldn't just give up when it does.
Well, the posted patch does fix things for me, pretty much. I'm still
seeing X lockups while the drive is in use - is the driver maybe
busy-waiting too much or something? It may be a more general Linux
IDE problem too...who knows. Does anyone else see similar behavior
with other slow IDE devices - maybe other IDE tape drives?
Anyway, I'm now a step closer to ditching my old DAT drive. Thanks!
