A method and apparatus for detecting lubricant depletion in a disk drive is provided. In some embodiments, a first end of the tension member may be secured to the aerial platform and the second end may extend unsecured from the aerial platform at a different elevation than the first end. The elevated design of the platform allows for the collection of the hazardous material runoff in a containment vessel deployed underneath. The second optical sensor is shielded against irradiation of ambient light. A removable protective layer covering the wells protects the electrode layer from attack by oxygen and water prior to being utilized to make the display. A holder for an inductive component includes the carrier device and an electrical isolation device.
