Build Your Own SATA Hard Drive Switch

Posted by timothy on from the there-can-be-only-one dept.

Mikey Win writes "ExtremeTech shows us a cool hardware hack that allows multiple operating system to boot without dealing with any tedious BIOS setup changes. How? By building your own SATA hard drive switch. The result? You can expect a longer hard drive life span, power supply load reduction, and partitions protected from becoming overwritten or corrupted."

  1. Power through data kills! by redelm · · Score: 0, Redundant
    If this is just a power switch, when what assurance is there it won't fry some drive? The most elementary rule in digital electronics is to supply power before data, and remove it after data.

    Switching circuits should not try to draw power from data lines! And if power is not supplied, they will. Perhaps some systems are robuse (3.3V isn't much), but I would not count on all circuits not having some overheat path.
