Common USB components between appliance and disk

  • Try a different USB cable

  • Try with or without a HUB

  • Try a powered or non-powered HUB

  • Try a different USB disk entirely

Same disk and enclosure models

Try a different model of enclosure and disk to isolate a problem model.

Appliance USB hardware

  • Try a different USB port, including the front and back of the CFA

  • Try using the disks with another host

    This will likely involve formatting them since the CFA uses Linux file system for archiving.

  • Copy large amounts of data to the disks and watch for failures

  • Reconnect and perform the tests
