When a hard disk is said to have "crashed" it means that the read/write head has come in contact with the magnetic medium. The read/write head is SUPPOSED to "fly" above the surface, never actually touching down.
The disk turns at such a high speed that if the head touches down it destroys the surface resulting in what is affectionately called a "head crash" or a "disk crash".
A computer virus cannot cause that kind of hardware failure.
Some viruses can affect data on other kinds of drives, as long as it can be written to, such as floppies and removable drives. Writable CD's are not likely to be affected.
