A message like this really does mean that your hard
disk can't keep
up with the demand for data. The cause of this however can come from
several sources. Since you are running several programs at once, most
likely synced together through the Jack transport, this means that they are
probably all trying to access data from the drive(s) at the same time, and
as you know, audio can be rather dense when uncompressed. So the solution?
It is often recommended to have a separate disk for recording audio and
whatnot to, that way, when linux needs to read info for running a program
it wont interfere with the audio data access on another disk. Of course
faster sata/serial disk drives will help as well.
Hm... that sounds a little bit disappointing, especially as I found out that
theres an SATA- disk in my laptop (Samsung X20). sudo hdparm -tT /dev/sda
results in:
Timing cached reads: 1592 MB in 2.00 seconds = 795.96 MB/sec
Timing buffered disk reads: 96 MB in 3.06 seconds = 31.40 MB/sec
Shouldn't that be fast enough?
Are there any people here who are recording to systemdisks with no problems?
As a workaround, I'm recording the Hydrogen track in Ardour, so that I can
switch Hydrogen of. I'm not very happy with it, though.
