Data Recovery Glossary > Head crash

Head crash refers to the physical or logical damage caused to the read/write and to the magnetic media of a hard disk. Head crash is caused by any dust contamination, electronic failure, sudden power failure, physical shock, wear and tear, corrosion or a sudden friction with the hard disk surface. In other words, head crash is the failure of the hard disk in which the head graze across the platter surface.

Head crash is also termed as "Click of Death". It is just a simple collision of the read/write head with the surface of the platters of the hard disk. Head crash eventually leads to the hard disk failure and may lead to tremendous data loss. Head crash can effectively destroy all the files and data rendering the disk unreadable.
