Strange Bug When Playing a mounted DVD

[Belarr]

I am running the most recent version of Daemon Tools Lite (4.11), I tend to make backups of most of my anime DVD's.
I mounted the images but about halfway through each of the images it just disappears from the drive listing.
The player software says it was ejected.
It never did this until about 2 weeks ago when running 4.10 and 4.11 does the same thing.

Virtual drive ejects if it cannot access image file.
Please specify more details about where your images are located (controller, driver etc) and your PC specs.

My HD configuration is as follows:

Maxtor 7H500F0 ATA
-- 93GB Windows
-- 93GB Ubuntu
-- 256GB FAT32

Images are located on the FAT32 partition, to be shared between Ubuntu and Windows.

Check system event log then for possible errors maybe.
