looking at your output, it's an external hdd
if i take my external usb hdd enclosure and take the hdd out of it, when i turn it on, it gets as far as yours does instantly;

followed a few seconds later with errors regarding scsi communication, naturally because there's no hdd for it to talk to;

so what it could be is that the enclosure is working, but it's not talking to the hdd or the hdd isn't responding
