Customer Rating:      Summary: I've Had NO Problems! Comment: I've had these disks for a couple months now and haven't had any problem with them going bad. I loved the price. Great quality! Would buy from again!!
Customer Rating:      Summary: Bummer! What happened!? Comment: I had the same situation as previous posters, I went thru a couple 50-spools of the 4x and had almost NO problems. Then I couldn't find any more of those and had to switch to the 8x... and now something like 3/4th of my current spool fails to burn with "power calibration error". I have a sony 4x DRU-500A.
Customer Rating:      Summary: Read this before buying!! Comment: I say read this before buying because I am not going to trash Memorex, I am going to explain what will go wrong and why. These discs should work for a while. Memorex used to be a very highly regarded name in fact. Recent Memorex releases have gone down in quality. I scanned and diagnosed some of these Memorex discs, and found out a few things...They have manufacturing label CMC MAG, the worst manufacturing label on the market. Memorex doesn't even make these discs! They buy them from CMC MAG and write Memorex on them! Some CMC MAG discs have gone bad and completely corrupted in less than 2 months! If you are using these for anything but temporary, stay away. The quality is good, while it lasts.
Customer Rating:      Summary: be aware... bad product Comment: I bought 50 DVD spindle. Used them all with no problem. Once tried to see the movies they all started freezing 1/2 way. I called my friend and he had the same problem. It looks like I have to turn off the DVD player for about 15 minutes and wait for the DVD temperature to cool down. The normal heat generated from the DVD player is affecting the DVD disks. Once I do that, it works fine. Unfortunately I already bought another 100 spindle from Best Buy, but these were worse, I recorded with no problem but it froze all together once tried to watch the movie. I tried 5 disks with same result. I returned them with full refund. I used generic DVD from Staples and worked great. I transfered some DVD's and they worked fine. I'm using Philips now on NEC DVD burner and they worked great. After doing some research and reading some reviews on chat lines I found that a lot of people having the same problem. One person said that Memorex use the cheapest die for thier DVD's. Please be aware, they might burn fine but when you need to retrieve the data is were you'll have the problem.
Customer Rating:      Summary: Unreliable Product Comment: While using this DVD-R, I had success rate of about 66% to 75%.
I did some research and found out some interesting things. First, I read internet posts describing Memorex 8x DVD-R media doesn't work well at 8x speed and that 4x is recommended for better result. So far this has worked. But this is very disappointing because this product is supposed to work at 8x speed.
Another post I read was much more disconcerting, because the poster wrote his Memorex discs, which he burned months ago, was no longer working and that he lost large number of files.
At this point, I'm considering purchasing different brand of DVD-R and backing up my files all over again just to be safe.
