Note: If you unplug the USB SCSI Adapter from the
computer, or the device(s) from the SCSI chain,
the operating system may not recognize this and
might think that the device(s) are still connected. In
the event that the device(s) and/or the USB-SCSI
Adapter is unplugged from the computer, and an
application tries to access the device(s), your
computer will hang. You must cycle power in order
to recover your system.
Hence, to disconnect a device from the SCSI chain,
always drag its icon to the TRASH first, then
disconnect the USB SCSI Adapter or devices.
