Well, within an hour or so of getting my new LogicPort logic analyzer hooked up, I’m at least noticing some symptoms that I haven’t seen before.
The drive is putting out(or the logic analyzer and my sx is seeing) very short time between pulses. Like 2.9us, 1.7us, 2.75us, and then gets back on track. Since my SX is detecting these edges, it’s writing a “1” for each of them. This is how I end up with double 1’s.
Now the next question is, is the drive really putting out pulses that are too close together? Or is this noise?
Odd enough, i tried a disk other than my test disk and I’m not finding any weird pulses. Maybe I’ll try another track on the same disk to see.
