Can I stop my external hard drive from going to sleep?

\n

Short answer: Partly. On Macs that offer it, turn off "Put hard disks to sleep when possible" in Energy (or Battery → Options) settings. Many drives also sleep by themselves, which only the maker's software can change. An SSD avoids spin-up delays altogether.
