DT Mac v5 disk not ejected properly?

Hi,
I'm getting an error notification when my Mac wakes from sleep that says the iSCSI mount (created by Daemon Tools for Mac v5) "disk not ejected properly". This usually happens when I unplug a USB device without first unmounting it. I'm concerned that my data may get corrupted.

Does anyone else get this error?
Anyone know if there's a way for me to fix it?
Is this a bug in DT for Mac? Should it be noticing when the Mac is entering/exiting sleep and unmounting/mounting?

Thanks
