Sorry for jumping in snoopy.
It appears to be an issue with any storage devices such as hard drives internal and external,CD/DVD rom,floppy and so on.
You may benefit from downloading new hardware drivers.

Now people asume that downloading and running a driver update means it is installed.That is just not the case.Some do install some do not.
Once downloaded all the relevent hardware drivers I would then open device manager and right click and choose update driver.This then will hopefully ensure the driver did install.Time consuming I know but it may resolve the issues.If the error occurs using external devices then update all items in USB section and such things as network.Update all storage hardware.
I would also power off the computer and check internal connections are fully seated.
