This item is from the Yet Another Enhanced IDE/Fast-ATA/ATA-2 FAQ, by John Wehman and Peter den Haan with numerous contributions by others. (v1.92).
OnTrack has a web site: <http://www.ontrack.com/>. Most importantly, you can find their Disk Manager FAQ at <http://www.ontrack.com/ontrack/faqhome.html>. There's also a bit about DM in section 13.1. If all of that doesn't help, contact OnTrack tech support at email@example.com.
Beware that some licensed versions are supported by the OEM rather than by OnTrack. In such cases the OEM usually offers help, FAQs etc. on their web site.
