A few years ago I found with my old 7100 that if I forgot the turn the external SCSI hard disk on at the same time or before the computer then all sorts of crashes and freezing were experienced. I did not know the cause at first and after a series of problems with the 7100 unable to start up properly I ended up having to reformat the internal hard disk. I had struggled with all sorts of utilities such as Norton etc and probably made the situation worse myself as I could not find the cause or solution until someone else identified the non-powered but connected SCSI disk. My advice is therefore to start any connected external SCSI at the same time as the computer or have it disconnected from the SCSI bus. Regards, Paul Anderson
