New case has only one exhaust fan. Its time to use the outdoor probe on my Radio Shack Indoor/Outdoor Digital Thermometer to see if I have a systemic problem and need another fan. This box is a lot quieter, and I like that. But cooked isn't fun either. Don't know what happened but I have two tapes which the drive refuses to accept. All others I have close at hand are "good" at least thru "mt stat". I'll take the questionable tapes to work where I have the twin of this drive. If it breaks there then I'll quit worrying and throw the tapes away.
