Asus DRW-24B5ST


How does the Asus DRW-24B5ST perform as a scanner? I believe it is based on the LiteOn iHASx24 C series? I used a LiteOn iHAS122 C in the past and it showed high PI Errors with known good media and I am wondering if this performs the same? Are there any firmware updates available and can it be crossflased to a LiteOn?
