it's unlikely that it's a disk problem. Most modern disks can read/write

= 208 mono-channels

Is the filesystem that you record to NTFS? There are some odd issues,
that some have been reported on #ardour IRC. I don't know the details
but with some version (or option) of the linux driver disk read/write
are always blocking with the effect that disk access can stall the
application for seconds.

If not NTFS, the only other thing that comes to mind is bus: Maybe the
internal disk in this box is connected via USB and you've plugged some
mouse into the same USB bus which forces it to 1.1 or something.

for starters:

cat /proc/mounts
lsusb -t
