So bunky you say that your disk drive is giving you problems? Well it seems that my drive would not read a good disk to save it's life. A quick trip to the macdoctor, 60,000 I/Os later, and the drive is pronounced fit for service. In the interim, another drive buys the farm!!! What gives? Somthing in the air maybe? Well I had to pick up the first drive anyway. I tell the tech my problems and with a twinkle in his eye he asks me "which side of the Mac do you keep your drive on ?" Well any true, red blooded hacker puts the drive on the left side, right? WRONG!!!WRONG!!!WRONG!!! It seems that the left side is where the power supply for the Mac is kept. So the mactech tells me that apple just came out with a blurb that says the drives should NOT be put on either the left side or the top (RFI). Well to make a short story long, I put the drives on the right side and PRESTO!!! no more problems. Will miracles never cease. If any of you have had this problem lets hear from you.

Sounds familiar. Being left-handed, it was natural for me to put the external drive on the left set of the Mac -and that's the way I first set the machine up. Within the first week I started having trouble copying files to the external drive, and things quickly deteriorated to the point where it claimed that every disk I inserted was unreadable. Took the drive in to my trusty dealer ...who could of course find nothing wrong with it. Hooked it back up and everything worked fine [you can imagine how sane I felt at that point]. That is, everything worked fine for a couple of weeks. Then the same deteriorata. So I started fiddling everything I could think of, and finally hit on the right-side-of-the-machine solution. And it's been all sweetness and light since then. p.s. Things also work perfectly well with the cable going straight out from the back of the Mac and the front of the drive facing away from the machine. But this isn't the handiest arrangement.

I've been working with a Mac for about three months now. My second
drive is on the *left* of the Mac. I haven't had any problems what
so ever, yet (knock on wood).
Does a minimal amount of time has to pass before the problems arise?
In which case there is still time to move my drive from left to right.

On the same topic, I keep my extra drive on the right side... but last week was a record setting event in the LA area. Temperature records over 100 years old fell to the heat wave. And my extra drive starting disliking disks. Now that it has cooled down a bit (90s and low 100s), things work better. But I'm still turning off the Mac when I'm not using it, 'cause the top gets more than "warm to the touch" after a few hours. --Darryl Richman, INTERACTIVE Systems Corp. ...!cca!ima!ism780!darryl The views expressed above are my opinions only.

The only time I ever actually saw a Mac have trouble with EMI/RFI from the power supply screwing up an external drive was when the drive was on it's side, right up againster the left side of the Mac. Since this blocks the vents on the hot side of the Mac, it's probably not a good idea anyway.

The media (coated polyester film, generally) of floppy disks has high thermal and humidity expansion coefficients. At high temmperatures, the data tracks can move enough to be unreadable by the drive. > But I'm still turning off the Mac when I'm not using > it, 'cause the top gets more than "warm to the touch" after a few hours. > Good move. I recently moved my Mac to my basement (oh, that's right, no basements in super-state CA :-) ) because my upstairs was too hot for the Mac's convection cooling to work well. I'll have to move it back in the winter for my own comfort, I suppose, but that's not a high price to pay for the increased longevity (speaking statistically, of course.....). -- Andy Hogan Rosemount, Inc.
