Morgan Posted September 16, 2006 Posted September 16, 2006 With "verify" checked I get a ton of i/o error messages after the completion of the burn session but have noticed that the DVD still works. For the time I have "unchecked the "Verify" box. Whats going on here???
LIGHTNING UK! Posted September 16, 2006 Posted September 16, 2006 It means your drive can't read what it just burnt. Are you using crappy discs by any chance? Is your firmware on the drive up-to-date?
Shamus_McFartfinger Posted September 16, 2006 Posted September 16, 2006 Bad media by the sound of it. Post your log so we can have a look.
blutach Posted September 17, 2006 Posted September 17, 2006 If you do any scanning afterwards, you'll find a whole lotta red areas. You have a bad burn and verify has picked this up for you. Regards

lfcrule1972 Posted September 18, 2006 Posted September 18, 2006 That's cos the standalone players compensate for some DVD errors I imagine cos they know that discs get dirty or scratched. Your DVD drive in the PC looks for perfect data off the disc, what it's saying is that your data, just burnt is NOT perfect. You have quoted Sony & Memorex as the brand but they don't make the actual dye on the disc. This varies a lot between manufacturers, the best is probably those made by Verbatim and Taiyo Yuden with some of the worst being made by CMC MAG. Take a look at a log from ImgBurn and see what dye your discs are using then look at the Media/Drives forum (link in my signature) and see some tests on most commonly used media, if yours is in there take a look at the scans etc compared to Verb and Taiyo Yuden dye. If you post a copy of your log we can check the dye manufacturer for you
polopony Posted September 18, 2006 Posted September 18, 2006 if you do some reading on this forum you'll see that Memorex with CMC MAG dye is some of the worst garbage there is and members have mixed results with sony also . Verbatim and Taiyo Yuden are the discs of choice .Try reading the memorex stuff 6 months from now
blutach Posted September 19, 2006 Posted September 19, 2006 But the dvd still plays even after all the error messages. I use Sony & memorex..... Playing/watching it is largely irrelevant. A bad sector or two might flash past without you knowing it. Or a sector that verifies incorrectly may simply have a byte or 2 wrong (how would you tell on the screen?). The true way to verify is to do a bit for bit verification. Once the md5 hash comes up identical, you know you're OK. As for Memorex, they are usually junk. Regards
Shamus_McFartfinger Posted September 19, 2006 Posted September 19, 2006 Sony aren't the best either. I know some Sony media (like their DVD-RW's) are actually Riteks.
