CRC Errors are most commonly associated with damaged or dirty media
That may be true with original dvds,along with encryption. Now when re-ripping backups,it's a whole new ballgame. The 1st copy has to be as good as you can make it,which means reducing those little PIE/PIF errors. Re-ripping backups is a pretty good way to tell if your backups are ok if you have no access to quality disc scanning test like nero,plextools,kprobe.
What good is a backup when 6 months down the road you need another copy of it,so you re-rip it and get hammered with CRC errors?
1) Use quality media to begin with-it'll prevent a lot of issues.
2) Keep the burner's firmware up to date,this controls the writing strategy to your specific media so it can be properly burned.
3) No paper/sticker labels. Major no-no
4) No multi-tasking during the dvd backup process
5) Keep to a basic 4x-8x burn speed. Quality media,faster burn,crap media-slower burn.
6) Keep the burn from reaching the outer edge.Keep the backup target below 4370 mbs with quality media,even smaller with crap media like 4300 mbs.
Now after using that formula and you still got CRC errors while trying to re-rip your backups,you got something majorly wrong with the dvd-rw drive that burned that 1st copy. Think all dvd burners are alike? NOT!
There's some crappy drives out there.Higher coaster rate,low compatable backups on stand alone players,and a lot more of those little PIE/PIF errors-even with using quality verbatim and taiyo yuden media..
I checked my discs and found that they are Maxwell
Maxell used to make some awesome media,which was made by Hitachi. If you look on the outer shrink wrapper for country of origin,the Made in Japan will yield the Hitachi's-which are mainly the +8x/some -4x/-8x speed.
Here's the manufacturers of Maxell media,and notice there's up to 3 different manufacturers on the exact same speed and format of maxells:
MAXELL Plus format:
+4X MADE IN TAIWAN: RICOHJPN-R01
+8X MADE IN TAIWAN: RITEK-R03
+8X MADE IN JAPAN: MAXELL-002-00
+8X MADE IN JAPAN FULL HUB/White Inkjet PRINTABLE: MAXELL-002-00
+8X MADE IN TAIWAN Full Hub/White Inkjet Printable: Cmag:
+16x MADE IN TAIWAN: CMCMag-M01
Maxell Dash format:YELLOWTOPS
-4X MADE IN TAIWAN: RITEK-G03
-4X MADE IN JAPAN: TY-G01
-4X MADE IN JAPAN: MXL-RG02
Maxell:GOLDTOPS
-8X MADE IN TAIWAN: RITEK-G05
-8X MADE IN JAPAN: MXL-GR03
-8X Made in Taiwan: Cmags
Seing all those different manufacturers,some people have have good results when getting the Hitachi,Ritek,or Ty maxells,and poor results with the Cmag maxells.
Maxell: For the best discs,which I rate as well as Taiyo Yuden or Verbatim,get the Made in Japan spindles. Same goes for Fuji and Sony.:clap:
