Detailed explanation-1: -A head crash is a hard-disk failure that occurs when a read–write head of a hard disk drive makes contact with its rotating platter, slashing its surface and permanently damaging its magnetic media .
Detailed explanation-2: -After a head crash, particles from the damaged platter and head media can cause one or more bad sectors. These, in addition to platter damage, will quickly render a drive useless. A drive also includes controller electronics, which occasionally fail.
Detailed explanation-3: -The most common symptom of a head crash is a clicking, screeching, or whirring sound-basically, if your hard drive makes any unusual noise, it’s a sign that something is physically damaged. Since hard drives don’t have that many moving parts, the read/write heads are probably affected.
