When should I throw an exception?

Andy Mc's C# FAQ for C++ programmers
This is the subject of some debate, and is partly a matter of taste. However, it is accepted by many that exceptions should be thrown only when an 'unexpected' error occurs. How do you decide if an error is expected or unexpected? This is a judgement call, but a straightforward example of an expected error is failing to read from a file because the seek pointer is at the end of the file, whereas an example of an unexpected error is failing to allocate memory from the heap.

Once you create that disc, you can use it as your master disc to load into the hard drive and make your duplications. No.

Animation: a Processing extension

How does a hard drive work?

FAQs
Hard Drives store data used by the rest of the computer. When a hard drive needs to read or write something its controller receives a request from the motherboard.

From the buffers the data is sent to the computer to be processed.
