FAT 32 File OverRun

Recently I started getting an error once Windows starts up. It is in a parallels box, not windows and it says FAT32 File Overrun. Windows freezes, shuts down, and trys to restart. Sometimes it will work for 10-15 minutes, then it does it again. Does it also in windows safe mode. I cant find anything on it. Any thoughts?

Running 2010 MBP, 8GB RAM, 1GB allocated to VM
Parallels 6.0.2106
Windows 7 Ultra 64 bit
Have 29GB left on my Virtual disk

 

I think the message probably says overflow and not overrun.

What version of Windows is this? There's no reason to use FAT32 instead of NTFS if the Windows version supports it.
FAT32 has several limitations, one of them is 4GB file size limit, this means it can't handle files bigger than that, and that's probably the problem, it's possible the file in question is teh pagefile or the hibernation file if you have 4GB of RAM assigned to the VM.

 

Nope it definitely says FAT 32 file over run. I only allocate 1gb of memory because that was a suggestion from parallels brides for a different issue. After trying again this evening, I again got the same error. I was able to get windows open enough to get to the command prompt. I checked the file structure and the drive is formatted as NTFS so why would I be getting a FAT 32 error
