transferring CDR to CDR

[daveman_84]

Hey everyone...new to the forum, first wanna say how much I've learned from reading new and old posts, it's great.

Anyway, I have a bunch of bootleg CDs I make and trade, most of them are Imation that I made and a mish mosh that I got from others (Maxell, Memorex (prodisc), Sony, etc). I just bought 100 Fuji's (thanks OfficeMax!) and I was wondering if it would be beneficial to copy all my CMC's and whatnot to the Fuji's because they are better quality. It's not an insane amount of CDs I want to copy, in the range of 50...what do you think, will transferring them all to Fuji make the quality better at all?

Thanks!
Dave

Your idea is a good one, but it would best if you had a drive that can be tested for C1 and C2 errors. The latest LiteOn drives can test burned media with CD Doctor or KProbe.

If a disc that was previously recorded has any C2 errors, it would be best to copy it to a new CD-R of good quality like your Fuji/TY's (which can be verified by testing). C2 errors are symptomatic of severe read problems, which may eventually become read failures.

I happened to just purchase a few days ago a Plextor 4824U, so I'm sure it can detect C2 errors. But I wonder, if my Imation has a C2 error, if I copy that CD wont I just copy the C2 error to the Fuji? I'll test my CD's for C2 errors....I'm waiting for my USB 2.0 PCI card to come in the mail, as soon as it does I'll test them. Otherwise through regular USB it would take a year!

Thanks

There is a lot of redundant information in a CD error protection scheme (CIRC), which is used to correct errors which are present in all recordings.

C2 errors are part of this error correction scheme, and lower level C2 errors are fully correctable. Unless your audio CD-R's have uncorrectable C2 errors, properly copying the discs to a high quality media will eliminate the C2 errors in the new copy.

You're welcome, daveman_84.

I have done copying from one cd to a better quality cd and the errors on the original were cleaned up from like 200 constant c1 errors to low 10 max. It had no c2 errors at least. I almost told my Step dad to let their sound man know his cdrw sucked but it worked and cleaned up well so I let it go
