it probably needs to be made more apparent that the forums are not the
primary support venue for ardour, even though we do try to respond to
most of the issues that come up there in some way.

actually, yes, they could. i ran into a situation earlier this summer
with a brand-spanking new, super fast system with two identical disks
(both SATA 7200rpm). one of the disks (the system disk - coincidence,
who knows?) was completely unusable for ardour - it couldn't record 3
tracks without a disk underrun. the other disk (formatted identically)
could handle 35+ tracks with ease. what is to blame for this incredible
disparity in behaviour? the disk h/w? the filesystem? the kernel i/o
scheduler? fragmentation? who really knows .... all i know is that to
assume that the fact that ardour reports the error means tht ardour is
to blame is premature ...

if they do not overlap, its not an issue. if they overlap, then you
either did lots of punches or you edited them so that they overlapped.
and *this* is an issue, currently.

ardour doesn't have a "RAID" implementation other than the capability to
spread files out across different disks. that doesn't happen unless you
specifically add stuff to the "RAID Path"
