Isn't scsi0 in this context just the first SCSI host adaptor?

Try looking into use the smartmontools
<http://smartmontools.sourceforge.net/> to get drive health statistics via

As far as debugging goes, I'd check that termination etc. is OK, then try
borrowing new cabling and a new controller in that order.
