817 Storage connected to a USB 3 PCIe card (or Tango combo card) gives an macOS error message upon wake from sleep.May-12-20
To minimize power usage during sleep, power is removed from PCIe cards. Because of this power-saving specification, a USB 3 PCIe card is unable to maintain USB port power during sleep. In macOS, this result in a storage device disconnect upon wake from sleep. The storage device will automatically remount, but the system reports a disconnect message. Because macOS flushes all caches before sleeping, this disconnect should never result in any loss of data.
