Which outcome disrupts recording when a hard drive overheats?

A)Loss of domain alignment
B)Oxide layer passivation
C)Head stiction increases
D)Reduced data transfer rate

💡 Explanation

Excessive temperature provides energy to ferromagnetic domains causing increased entropy; this drives domain randomization driven by the Curie Temperature, because domain walls become unstable, therefore, magnetization is lost and the data becomes partially garbled rather than other error modes.
