Depending on what version of photoshop is causing the error to appear you will delete the following file:
Adobe Photoshop CS5 Prefs.psp (for 32bit version)
Adobe Photoshop X64 CS5 Prefs.psp (for 64bit version)
After opening up photoshop, navigate to Edit > Preferences > Performance
There will be a section called Scratch Disks; verify that D:\ is the one checked as active, not C:\ and change it if necessary.
After restarting photoshop the problem will go away.
Notice that if this preference file becomes corrupt again, the previous steps have to be taken again to prevent permission errors.
