I got my new Greaseweazle v4.1, and after couple of uses, it stopped working reliably.
When reading flux I'm getting what seems to just noise, and when reading a simple .img, I'm getting "Ignoring unexpected sector" for each sector.
I suspected the usb cable, the floppy cable, and the floppy drive, so I replaced all of them but to no avail.
I also have a Kryoflux which works fine in the same setup.
I noticed that when connecting the floppy ribbon cable to the Greaseweazle, the motor starts spinning, even when the Greaseweazle is disconnected from the computer.
I tested the Greaseweazle 34 pins with a multimeter, a found that pins 10 and 34 are shorted to ground. I compared it with the Kryoflux and there the pins are not shorted.
Looking at the schematics (with my limited electronics knowledge...) it seems that these pins shouldn't be shorted...
Is my Greaseweazle toast?
