I've just replaced my scratchy Hitachi for a Samsung, I thought the disc scratching was a Hitachi only problem. Oh well, I'll stick with it now, I felt a lot happier as soon as I tried the first disc, it sounds alot more smoother and responsive but the main thing is that I don't get that feeling that the drive's chewing and mauling my discs. I'd have a bad feeling every time I put a disc in, I remember burning The Darkness on a precious Verb and as soon as the start screen had loaded I got an dirty disc error, checked the disc and it got scratched. The same thing with Nascar 08 on loading the first race circuit and I burnt the second Lost Oddysey disc 4 times!!!! That was when I had enough and did the padding and reduced the read speed and it sort of worked, it didn't scratch the Lost Oddysey disc at the same point, it was during a cutscene and it wasn't as deep that time.
After that I didn't really use my 360 so much in fear of it shredding my discs and like I said in my prev post the laser conked out on me recently so I opted for a new drive, just not a Hitachi from my history with them. I've a stack of games that I've burnt but not tried and now that the new drive treats my discs like a butler wearing white gloves I'll be catching up, I've skimmed through a few, I'll be having a stint on Viking Battle For Asgard next, then Dark Sector all the way to the recent stuff, Don Kings and Civilization so I think that's around 20+ plus to catch up on, I know it's a tough job but someone gotta do it.
