Spybot Can't Find My Hard Disk?

I have been having this problem on and off for some time, depending on the updates I obtain.

After the most recent set of updates were installed, Spybot began doing this again. As I ran the software to scan for problems, it would give me the message that there was no disk, and stop the scan. Clicking any of the buttons stop, continue or retry, allows the scan to continue, but it has to be clicked once for each type of check being made. Considering how many types of things are being checked for... this makes it impossible to run the program.

This doesn't always happen though. It only seems to happen sometimes, and the rest of the time the scan runs without a hitch; before this last update for example, the scans ran perfectly.

Anyone have an idea why this is happening?

The specific message I get is:

Windows - No Disk

Exception Processing Message c0000013 Parameters 75b6bf7c 75b6bf7c 75b6bf7c

Hello,

This is a known problem which can occur in Windows.
The problem is usually caused by having Drive C assigned to a device with removable media. If you have that situation then either put media in Drive C or reassign the device to another letter.

There are instructions for reassigning the device to another letter here:
No Disk Error
