Thanks lots, Jeremy.

    I haven't used hdparm; I see it does a lot (much
to learn, per the man page).

    I'm thinking of writing a for loop and capture
start and end time: will that be useful? (Probably
I'll use DASH, Python, and C, just to compare
those three.)

    I haven't had the need to use lspci or lsmod or
most other diagnostic tools (not till now, so I'm
mostly lost).

    More thanks, I'll probably be able to send info
tomorrow (machine is not home).

Hiya,
    I've got a Zareason media box
http://zareason.com/shop/MediaBox-5440.html
with 8 GB RAM running AVlinux (a debian flavor);
I use Ardour pretty much exclusively, that and
the vi editor.

    The system can record a single track with no
problem. It occasionally fails if I try to record
two simultaneous tracks. If regularly fails if I try
to record four or more tracks.
    The complaint is always that the disk system
cannot keep up.

Question: would just blindly replacing the spinning
disk with SSD be a likely fix and an overall good
idea?

Question: what info should I capture and email to
get appropriate help?

Question: what commands will yield useful info
for this diagnosis? (I like the command line but
forget which commands do what other than the
usual suspects for basic use.)

Hopefully, with thanks,
jim in SF

Hello Jim,

That's really weird, disk IO shouldn't be an issue with such a machine.
Maybe you could test the disk throughput and post the results here
together with the command you used? You could use tools like hdparm or
dd, there are quite some examples out there.
And what is the output of cat /proc/mounts for the drive in question?

Bye,

Jeremy
