Final answer:
A stoppage of the hard drive resulting in data loss is known as a Crash. It can be due to physical or logical issues, often requiring professional recovery services if it's a physical crash.
Step-by-step explanation:
A stoppage of the hard drive that often results in data loss is called a Crash. When a hard drive crashes, it means that the drive has experienced a physical or logical failure that prevents it from operating normally, which can lead to the loss or corruption of the data stored on it. Logical crashes can sometimes be resolved with software tools, but physical crashes typically require professional data recovery services, and can sometimes lead to permanent data loss.
