The dialog may say something like "the drive is full"' but that is just because that is what someone typed in the dialog text line many years ago.




...well aware of misleading or just plain wrong error messages...

Good to see you have a sense of humor!
 
After you check the DPC latency you'll probably have some sense of what is going wrong. ;-)
 
 
 
I was using a Class 10 Compact Flash card to record a media stream at 35Mbps last week and the device had a buffer over run which interrupted the stream and stopped the recording mid way.
 
16 tracks of mono 24/44.1 equals 11.2896 Mbps.   fixed: 16.934.40Mbps
 
It's worth a try... but I'll bet something running in Windows interrupts the process.

Video card drivers (especially the ones with HDMI audio), wifi drivers, anti-virus and disk indexing services have been known to interrupt smooth performance, though usually the issues are more severe. Are you reasonably sure none of these are interfering?

Huh?  Why doesn't 44,100 * 24 * 16 = 16,934,400?

You are correct and I was mistakenly quoting the rate of a 16 channel a 16bit/44.1kHz stream. I apologize for the mistake.

If you're recording live performances, I think 11 ms latency is unnecessary and could cause the machine to hiccup if anything else happens on the computer while recording.
Not that it has anything to do with your current problem, probably, just sayin'.

I saw that too when I started pulling data together.
 
Although that exposes another mini-beef I have.  You can only make configuration changes for a particular interface when you're actually connected to that interface.  That takes even more time during Sunday morning setup when time is at a premium.
 
Hmm...what I could do is just edit the AUD.ini that I use for the X32.

Did you have a chance to run a DPC latency tool?

I turn off just about everything I can when recording on laptop. I saw you don't have laptop comnected to wi-fi, but also disable the wi-fi adapter completely when using Sonar or any other latency affected product. Disable background services and scheduled maintenance items like scheduled disk defragmentation. Also software update checks that often load at startup like quicktime/ itunes, various adobe programs, java, etc. I recommend going through your list of programs that load on startup every now and then because tons of things from printer apps to various proprietary "assistant" programs tend to load automatically and check for updates too. Just disabling wi-fi and Nvidia's crappy audio drivers alone reduced my latency exponentially. Good luck.
