For people having problems with getting their LiteOn iHBS112-04 to do disc quality scans using Opti Drive Control please try the work around that I've listed below.
Symptom: When you click start the scan starts up and stops at 6mb.
1) Start "Disc Quality Scan".
2) Wait until "Spin Up Drive" speed reaches 100%
3) Once "Spin Up Drive" speed reaches 100%, click on "Speed" and select any speed. This should get the scan going.
I hope this helps.
