← ScienceWhich risk increases when a hard drive’s read/write head exceeds its Curie temperature?
A)Sudden drive head catastrophic mechanical cracking
B)Permanent loss of recorded ferromagnetic data✓
C)Runaway thermal expansion in the spools
D)Disk platters developing microfractures quickly
💡 Explanation
Permanent data loss will occur because exceeding the Curie temperature causes loss of ferromagnetism in the head. Therefore, permanent damage happens, rather than simply mechanical destruction or physical change at the disk, because information is no longer magnetically distinguished.
