Get a load of this.
 
My daw is a desktop running win 10. It, and everything connected to it is on a hard switch. That is, the current to it all is cut via a hardware switch. No battery backup anywhere.
 
The other night, Sonar crashed while editing a vVocal region. As is customary, as I looked at the crash dialog the buffer looped on a small segment of the region i was editing going, niet niet niet niet niet niet niet niet niet ........ I'm sure you've all been there. So I do what I always do, and close Sonar and because Sonar is always ever running when this occurs, I shutdown windows and because I was tired, just clicked off the hard power switch to the "studio" and went upstairs.
 
Two days go by.
 
Yesterday I went down to the studio and powered up the hard switch. My daw is set in cmos to auto power up upon AC power loss, so up it came. As soon as windows came up, niet niet niet niet niet niet niet niet niet....... WT!!!????
 
I started wavelab because it's quick to start to re-init the pci rme card that was still looping that audio segment from the great beyond and the looping sound quit. Ok killed it. :-)   Started Sonar up and loaded a file only to have windows bsod on hypaudio.sys which is my UAD-1 card that is largely unused anymore. I powered off the hard switch again, brought it all back up via that hard switch again, and away I went a-editing a Saturday away.
 
How the niet niet niet niet niet niet niet niet niet buffer could stay alive with no power to the chips and no battery backup or anything is beyond me.
 
 
 
 

Sounds like you have the Russian virus there!

Windows has something called a "hybrid shutdown" that speeds boot time by basically logging off the user but only hibernating the OS itself (or something like that).

Windows has something called a "hybrid shutdown" that speeds boot time by basically logging off the user but only hibernating the OS itself (or something like that). 

I'm killing power to it for more than 36 hours in this instance. Does it persist the state to the disk and reload it? That would both suck and suck.

It hibernates the OS, so it essentially writes the contents of memory to disk to allow for fast booting.
 
I don't remember the details, but my recollection is if you do a "restart" it does a fast boot rather than a full restart vs. a "shutdown" that actually shuts down the OS (and then it reboots slower).
 
Did you power off the DAW itself (which might or might not do a "full" shutdown) or power off a power strip or something like that feeding the DAW (essentially crashing it)? I would expect it to do a full restart after a crash.

"Sleep" puts what's going on into RAM and shuts everything else down (for a quick restart).
"Hibernation" puts what's going on onto your hard drive and shuts everything else down (for a slower, but still snappy restart).
 
"Hybrid Sleep" puts what's going on into RAM and onto your hard drive, just in case.  Depending on when you restart it will use RAM, if it's still there, or your hard drive.

I shut down correctly, then cut power to it and it's peripherals.
If win 10 persists the state of things to disk then that explains it. It was doing the looping buffer thing as I shut it down.

Hi Bit
You've provably got the fast startup option enabled in windows (=default setting)

(It saves the memory state to disk for faster booting?)
You can change it in the windows settings.

Thanks M@. I'll check that.
