I would not want to record to an external drive, especially not from an
external sound card, but I don't know the tweaks you undertook, nor your
soundcard nor your software nor the temp file configuation options if
any of that software.

You're making simultaneous demands on both firewire and USB, and the
system can't cope. You have little control over resource allocation
as it's a laptop. This could be a tricky one.

Is there a latency (and hence record buffer size) setting for the
Edirol? What is it set to? Does increasing it help?

In Windows XP, what is your setting for Processor Scheduling?
Programs or Background services? Try the other one.

What happens if you record to the internal hard drive? It may be more
capable than you imagine. You probably have enough room on it for
work-space. Project folders can be transferred to the external drive
for storage.

Also, confirm that your laptop DOES have USB2 ports. USB1.1 won't
cut it.

The buffer is set to "Min" which gives me a latency of 7.5 ms in and 4.3
ms out. i've increased it one notch and it seemed to help.

processor scheduling is set to 'background services'.

i got the external drive because i was having trouble when recording to the
internal drive.

thanks for the suggestions.

So increase it two notches. Does the problem go away?

The same problem? With the same low latency setting?

In Device Manager, look at Properties/Policies for your external hard
drive. Optimised for Performance?

Also, you might try turning off Lower Latency in Device Setup/VST
Multitrack/Expert.


Going back to your OP. If the disk light only flashes every 30
seconds you are writing data in BIG chunks. I wonder why?

You can only write a sector at a time. It is buffered in the file buffer
till then.

i've just noticed something i should have checked a LONG time ago...the hard
drive light flashes when the computer is idle, with no applications running.
i now think it's a windows thing and not related to the soundcard or cubase.
ugh. i'll keep plugging away until i find something.

Windows always has stuff running. You can turn some of it off (in fact
most, if you're using an off-the-shelf installation) but you can't
turn everything off. Check one (or many) of the web sites that explain
how to optimize your Windows PC for audio applications.

That's naughty. But if your glitches coincide with your audio data
blocks being written to disk, not with these background accesses....

What file system? If NTFS, is Indexing turned off?
What processes are shown (with no programs running) when you press
CTRL-ALT-DEL?
