Summary: Yes, They Are Bad
Review: I just wanted to add to the negativity of those who have written before and perhaps save some poor soul the aggro of buying and attempting to use Sony CD-R's. In a word, they stink. I purchased several spindles, and they have been uniformly bad, with many bad discs in each spindle. Avoid them. A better alternative are the Memorex CD-R's which contain only one or two bad discs per spindle. Be kind to yourself and don't buy this brand until Sony makes some attempt at quality control.

Summary: It's a SHOCK.
Review: I met some problem as other people said.
Buy whatever brands just do not buy this Sony brand.
Others are cheaper than it, and they won¡¦t mess your work up.
I have never got a horrible blank cd-r.
Never ever buy it.

Summary: You have to be kidding!
Review: I must admit. I ignored the previous review by Jon in Florida, and went ahead and bought these CD's thinking Sony is a quality company, so they can't ALL be bad. Well, I think I topped his 65% failure rate. The first 8 CD-R's I tried all had errors! I've gone thru hundreds of competing brand CD-R's with maybe 1 or 2 failures. This is ridiculous. I've used cheap CD-R's before, and you pay the price. I would classify these as cheap.

Summary: These CD-R's worked great for me.
Review: I use Nero 5.5 and 6 Ultra to burn VCD's with these disks and they have worked great for me. I have not had a single disk-related error and the picture quality is excellent.

Summary: Truly Infuriating...A BAD PRODUCT
Review: Im not taking this crap, I am taking these back to the store tomorrow. I have burned 5 and only 3 of them even finished burning, the others had skips that were not hard to find. I cant believe how cheap these things are, you can see through them in some places(!) it looks like someone poked pin holes in em, in other places on the CD there are lumps. What the hell does Sony do, dump a little grit into the mix before they make a CD?I bought some Imation brand CDs, they were cheaper and I only got one bad CD out of 50. I know this is not my CD-ROMs fault, it dosent like cheap crap and Im not going to use it. Any decent brand of CD youll not be able to see through them, the surface coat of the Imation CDs is thick and they are durable. These Sony CDs are a worthless product.

Summary: Consistently Bad
Review: Just wanted to chime in and reiterate what everyone is saying ... Sony CD-R's are extremely unreliable!

Summary: Surprised by a bad product from Sony
Review: Like others who have written here, I chose the Sony CD-Rs thinking that they would be of a good quality, bearing the Sony name. I use Nero 6 and Windows XP with a modern CD writer at home, and a Phillips DVD/CD writer at work. Nero produces endless "drive speed errors" with these CD-Rs, whilst changing over to a different brand of CD-R immediately cures the problem. Avoid!

Summary: I must have gotten a very good batch
Review: Luckily I haven't had the problems some reviewers here have had. I bought several of these and after burning over 100 I haven't had any problems. I usually get at least one or two per 50. I suspect the bad cds are in the same batches. I'm really very happy with these Sony CD-Rs. They were on sale at an extremely low price at Office Max and have held up very well indeed. After reading some of these reviews I'd buy one 50 pack to test. If you have a good pack the rest are probably from the same batch.

Summary: WARNING! do not buy Sony CDR or you will lose your data!
Review: Please do not buy, look for a different brand. You will lose data. I am furious how many Sony's CDRs I have replaced. They are the absolute worst product out there. I don't know how such a great electronic company would leak such low quality, unreliable CD-R. The problem I have with Sony is overtime the CDs become unreadable. It said not MS-dos error or something when you try to copy the data, basically it become unreadable. The surface of Sony CDR is a smooth pearl. After 1-2 years they start to fake off on the edge like watermark. Not because of careless, but of the CDR surface quality. Other cheaper CDR I have for 3 years (storage in the same location as the Sony's CDR) are still readable and don't fake. I lost some important data with at least 4 Sony's CDR. The files at the outer edge are affected the most. I though the smooth pearl color of Sony was very pleasing compare to other ugly blank CDR. TDK is now my CDR of choice now. It has a clean look and it CDRs are more readable on any cd-rom then Sony. I am in a progress of reburning all data that are on the Sony to TDK. Again, Warning: Do not buy Sony's CDR.

Summary: Don't waste your money
Review: These CD-Rs are terrible. They have no capacity whatsoever for overburning. I get frequent errors, and I hear the lifespan on these is not very long. Put all these flaws together with my gut feeling that, despite getting a 2-for-1 deal, I'd rather have spent 20 bucks on some Fujis or TDKs which have worked well for me in the past.
