I hope folks read this comment before proceeding to attempt a Sleep/Wake button repair on the iPhone 5! Apple has an iPhone 5 Sleep/Wake button replacement program, free, for iPhone 5 devices manufactured through March 2013. See program details at https://www.apple.com/support/iphone5-sl.... Don't do this yourself if you don't need to. It's a difficult repair.

This works beautifully with the WD40EZRX Western Digital Green 4TB 3.5" SATA3 64MB Buffer Hard Drive on a Time Capsule MD032LL/A (4th Generation) running firmware 7.6.4.
