I've tried all possible combinations, but I couldn't reach better results than these: PI Max : 88 PI Average : 6,97 PI Total : 218586 PIF Max : 5 PIF Average : 0,10 PIF Total : 3185 http://imageshack.us/f/405/kprobearkhamcity24xwith.png/ 1. Am I good to go with this backup? I've done tests with nero discspeed, too. With other coaster it gives me the final result, but with my best backup the score is 95 till 50% of operation, then magically the score turns to 0 till the end and no result at all. 2. So wtf is with nero discspeed and my best backup score? http://imageshack.us/f/39/eeprombitsettingls.png 3. Is this good (above picture) or it's better to change DVD+R and DVD+R DL to DVD-ROM? Someone on TX forum says that he/she makes better backups with Smart Burn disabled. I think I shall try this one, too. 4. What do you think? Thought it may be good to format my HDD and install Win7 again. It's been a year from my last format & reinstall. 5. Do you think it may help with burning better backups? If you're an expert and you can answer any of these questions I will be grateful. Thank you.
