Disk Space Meter is in the red, but i have 48.5Gig free space on my data drive..?

Hey guys.
 
So i am unable to load a project i'm working on in SonarX3 - it loads a bit, and then hangs.  I noticed that my Disk Space Meter is in the red, so i looked up what that might be about and got this:

Disk Space meter.  Shows the amount of available space on the drive where your wave data directory is located. The tooltip shows the actual remaining disk space on your audio disk.
Haven't found much more than that.
 
In this case, is 'my wave data directory' the audio folder for my project? 
The audio folder for this project has 6 or 7 Gigabytes of recorded audio in it
The project data hard drive (500Gig capacity) has 48.5 G available space.  Is this OK?
 
Does the number of tracks affect the 'disk space'
There are a lot of tracks in this project - would that affect the disk space meter?
 
And finally, what/where is this tooltip that shows 'actual remaining disk space'?
 
Thanks for your help!
 

Thanks robert_e_bone.  It is/was set to >1024.  Should i try >2048?  How about >4096?
 

I think slarta is on the right path.

I would also be concerned that you only have 48gb left of a 500gb drive. Once a mechanical HD gets over 3/4 full, it's time to do some house cleaning because it's performance starts to degrade after it gets over half full.

First trouble shooting action is ALWAYS to run a scan disk test.
 
Is it only the one project doing this?
 
And move some of the projects to another disk. If you can load other projects use save-as to another disk.   
 
Defraggers want at least 15% free space.
 
And: make sure the system is not placing a pagefile on the disk.
 

you can't expect a drive that is 90% full to perform well. you need a new drive to move your audio to. and don't let it fill up more than 50% (rule of thumb from the video side).
 
i just picked up a wd 4gb usb3 for $149. 2gb are under $100.

yeah, tb, my bad.

Your Recording and Playback I/O buffers effect your DISK %. The lower the settings, the more work is put on your DISK. I suggest raising it and getting at least a 7200 RPM hard drive for audio only.

Actually I seem to keep reading that a SSD drive is best for your C drive-- OS and Programs, and a standard SATA 7200 Blue or Black drive for the audio and projects.
SSD drives are pretty small still dollar for dollar so I can see this logic.
I'm still buying 1TB drives as I think they are the best bang for the buck.
Pretty hard to fill them up if it's just Sonar.
Sample Librairies are another kettle of fish but I don't have anything more than what came with Sonar. 

Hey, thanks for the suggestions, jm24.  I didn't know about safe mode.  Yes, other projects open.  It's just the last two saves of the one project that won't load.  I wouldn't be surprised if it the biggest project i have ATM.
I'll definitely give safe mode a go, right now.  Is safe mode pretty self explanatory - run and follow the promts?
 
 

I never use save only save-as to a new name.
 
Do it to a new folder.

Yes

Then close.
And try to open the new project.
If there is a problem it could still be a plug.
 

Save it with "save as" to your back up drive.. I wouldn't continue with the drive you are using at this point.
