Final answer:
A head crash is when a read / write head touches a platter.
Step-by-step explanation:
The statement is true. A head crash is a term used in computer hard disk drives where the read/write head comes into direct contact with the platter, causing physical damage. This can occur due to various reasons, such as sudden movements, impact, or mechanical failure.
When a head crash happens, it can result in data loss and permanent damage to the hard drive. The platter surface may get scratched or damaged, rendering the affected areas unreadable. Proper handling and maintenance of hard drives can help prevent head crashes.
