I bought in ComUSA 850MB CDRs .
But, my CDRW do not like to recognize them as
850MB, it says that it is 702MB media.

I checked : Creative and Acer RWs.

Any ideas?
 
lobo> Your burner has to support the capacity. Chances are that those two do not.
Chances are that the highest capacity it will recognize is 700MB, hence recognizing the higher capacity disc as 702MB.

There are also 900MB CD-Rs available nowadays, but again, your burner has to support that capacity.
 
Hola!

I read, test and earn some knowlegements from it.

Really, I can write slightly more than 700MB to 700MB CDR with owerburn.

Also, my Creative CDRW 8433E can wrote 850MB CDRs. Not each software supports this size. Also, I found, that some CDR blanks, like CompUSA can be nonreadable ufter burning - only 3 from 10 was read without errors. The PNY blanks has better results - 8 from 10 was good.

Ha-ha! Be away from chip alien CDRs :bgrin:
 
English can be your friend. Really.

Anyway, yes, with overburn, you can extend the capacity slightly. There are some issues with it though.
1) You shouldn't expect more than a few MB worth of extra data on the disk. Figure that, at best, on a 700MB disc, you'll get 710MB.
2) Both your CD mastering software AND your burner must support overburning. Not all do.
3) If you try to overburn too much data, you could potentially damage your drive.
4) Any drive will be able to write to an 850MB disk. However, it won't recognize the full capacity if the drive doesn't support that capacity. It's pointless to buy 850MB discs if the best you can hope to acheive is to write 700MB to it, when you could buy 700MB discs for less money.
5) 8 out of 10 is only good when compared to 3 out of 10. An 80% success rate is absolutely pathetic. Good media + good hardware = good burns. I'm still waiting to burn a bad disc with my burner, but I buy good media and have a good drive. I've burnt roughly 700 CDs in the past 2 years, and have never burned a coaster that wasn't due to my cancelling a disc mid-burn.
Both PNY and CompUSA media are crap, but PNY looks good next to CompUSA only because CompUSA is crappier than PNY. Look into Imation, TDK 100% Certified (not Certified Plus), Verbatim, or Fuji. All will be significant improvements to the point where you could actually verify that your burner is causing the coasters.
 
Hello!

Thanks For Your reply!
It was good and useful. I quote following :

Unfortunately, english is not my first language, even it is not the second :(
Another problem is : sometimes I do not know what I want to say.
The coincidence of two these features can to hurt
and to insult anybody :(

So, I am very sorry, if something wrong
