Seems I'm not really lucky with buying media.
First of all there was this Verbatim DLP 50cd spindle which would have those C1 error spikes in the mid of cd. Now I bought a spindle of MoserBaer cds, which I thought was fine (low C1, no C2, fast burning, strong protection layer), up till yesterday.
Yesterday I burned cd, and it didn't work. It would just stop at one file, and give me CRC error. Other files were working fine. I freaked out, and burned another copy.. this time checked box near "Verify written data" in Nero. Well, it burned fine, went throught data verification, and at 93% it failed. CD would just slow down, and inaccesible files would appear. Just for sake of curiosity I burned one more cd, and same happened, again soemwhere in the end of cd.
I was scared - is it my burner? Then I remembered I still have few of those Verbatims lying around - took those, burned 3 or 4 in a row - and everything was fine.
Hmm I thought. I took MB's again, and burned this time at 40x. Data verification passed, though KProbe showed some C2s, again at the end of cd.
Funny thing, I had about 20 cds burned from the top of that MB spindle fine - no errors. And now this happened. So I thought to myself, let's try some from the bottom. And few worked. Then few didn't. As of now I have 10 broken cds lying around.. all with errors at the end of them.
So I'm thinking to myself.. CD burning is still risky buisness.. It's still far from 2.5min per CD - since you allways have to run Data Verification process.. I mean, come on, even CDs from same spindle can be faulty.
I made 4 mistakes in word MAMA.. and got BEER!
