Mmmm, I always get high PIE and low PIF, does it mean anything? Defective drive? or just bad media? Thanks!
Bad media.To check if you have a good drive, try with quality media such as MCC003, MCC004, TY T02, TYG02.
Yep, crappy media would've been my answer. Go with what Zevia said for the best results. 4x Ritek DVD+R's also do well if they have a RicohJPNR01 media code. Not sure how the R02 and R03 media codes do but think scans of them looked pretty good as well.
