For Xenix, we chose: Cyl. 977 Hd. 5 Precomp 300 Landing zone 976 Sect/Trk 26 For some reason, which we haven't bother to figure out, selecting precomp 0 or None will cause system divide overflow when installing Xenix. In general MR535-U00 is very reliable drive. We have installed a few hundred of them last year and have only seen 3 malfunction ones. However, the DTC controller is relatively unreliable, and the defective rate is a little too high (relatively speeking).
