I was putting a new hard drive on my Macintosh SE. Very scary because it is an all-in-one computer and you have to work right under the CRT. Anyway, I put the harddrive in, put the case back on, and fire it up, it starts to boot and then cannot find the hard drive. I take the case off and then all of a sudden it boots just fine. I put the case back on, and then it will not boot. I went back and forth several times and I still never figured out what it was, but at lease I got it working reliably now.
