Which of the following is NOT a typical use for an external hard drive?

An external hard drive is primarily used for storing data, backing up important files, and transferring data between computers. It offers additional storage capacity and portability, making it a popular choice for backing up critical information and facilitating data transfers.

The option indicating data retrieval from optical discs is not a typical use for an external hard drive. This task is more commonly associated with CD/DVD/Blu-ray drives, which are specifically designed to read and sometimes write data to optical media. Unlike optical drives, external hard drives do not have the technology to process data stored on these types of discs. Thus, using an external hard drive for data retrieval from optical discs does not align with its intended function or usage.
