This rewiew is for rewriteable media only!

These CD-RWs are very low quality. I have been using them for a year now and they are bad after erasing them 2-3 times on AVERAGE.

There must be a reason why Fujifilm only produces 650MB and does not offer 700MB disks with phase-change medium! (Fuji disks are my most dependable CD-R medium.)

I have used them with multiple CD-writers, packet writing, UDF, digital-camera, the pocket version 210MB/24min and the full version 700MB/80min. The pocket version for my digital camera (CD-MAVICA) is loosing pictures (read-errors) after 2x erasing the discs. Generally I cannot rewrite the discs or erase them with cdrecord after few times (MEDIUM ERROR).

Their ATIP information is as follows (so that you can distinguish them from other 'brands' that use the same discs):

I have tried one hundred of these CD-RWs on three different burners (the first 50 were sent back to the manufacturer at my expense). The results are as follows: 70% will not complete the writing process. 10% completed the writing process but were illegible at a later use. 15% would not write a second time, and only 5% were reliable beyond 2 writes and multiple reads.

You might say "hey these are relatively inexpensive, so even if some don't work, I am still ahead of the game." The reality is these CD-RWs will be a big time sink for you. Your PC will stall and stammer, your drive will make strange noises, often for several minutes, as it attempts to read these CDs. Writing is even a bigger waste of time - you will be alerted there was an error in the writing process while 10 - 15 minutes into the process (being only 4X).

My advice is to buy the competitor's higher price version and save your TIME (and get value for your money).

PS: I see the price of the competitor's equilavent item is now lower than this brand, so choosing is a "no-brainer".

I've had mixed results with these Memorex CD-RW discs, having used them on both Windows NT and Windows XP PCs. The discs oftentimes work fine, but more times than I would have liked I've started to add files to an existing disc only to discover that the disc has become unreadable for some reason. This happens even when I use the discs on one PC alone (it happens much more frequently when I go back and forth between computers). I do back up some of my important files on these discs, but I would never depend on them as my sole means for recovering files lost in a PC crash. I'm sure Memorex CD-RWs such as this are quite common among workplaces, as they are relatively inexpensive and widely disseminated. For basic Word/WordPerfect and spreadsheet files, they are OK for the most part. I wouldn't trust these things for graphics or other large files, however, and I certainly would not trust them with really precious files. And whatever you do, make multiple backups of your important files or, if at all possible, make use of more than one backup device.

These are CD-RW discs, of course, so they are made to order for saving text files, spreadsheets, and the like; if you want to save music files, you'll want to use CD-R discs; CD-RWs won't play in standard CD players, and only CD-RW allows you to reinsert the disc and add files at any time (until the disc gets full, of course - it holds 700 MB).

Do Not buy this brand. I have used Philips CD-RWs, they work pretty fine numerous writes and erases later.

I bought these from J&R computers, I dont know How I will return these to them now, probably at my own expense. The question is not of money, I spent 3 full days in trying to figure out what's wrong.

I don't know how Amazon still displays this when somebody does a search. Nobody should sell this product.

If I could rate it a zero, I'd rate it a -10! Stay away from these! I've saved files on over 100 of these. Everything seems fine until I try to retreive something out of them or remove a file. Then good luck trying to open it back up. It'll say the disc is corrupt or cannot be read at all. And I've tried this on 3 computers. Same thing. Yes, you can imagine my fustration that only 5 discs had info. ARg!!! Please, stay away from these. You have better chance of saving your stuff hand writing it and taking months to file it than getting these to read anything!

And please check your discs immediately after writing. Don't wait till months to find out that your data isn't there.

If you have to get these, copy your data somewhere else and write. Don't cut them and lose them into the blackhole that is Memorex!

They are everywhere but just because they're everywhere and the cheapest out there, and have been around a fairly long time doesn't mean they work. Please Memorex, how can you call these Cd-RWs??? Wish I read all these reviews!

At less than a dollar per frisbee, this is the best price I can find for frisbees. They don't fly very well and they break relatively easily, but this is the best value I can find for 25 frisbees in one place.

A lot of people are disappointed because they expect to be able to use these discs as rewritable CD media. The problem with that is, they don't work very well for that either. I, too, tested this for myself.

Using Nero Burning ROM, I tried many times to burn different kinds of data onto several of the discs -=AT 4X=-, just like you're supposed to. IT WORKED! It burned fine. Then it took 5 minutes to open a simple HTML document on the burned disc. Subsequent trials run with the "Verify Written Data" checkbox checked revealed that every other sector or so was unreadable after burning. It's like writing with a white crayon, except this is white paper. This persisted on several OTHER computers with different CD burner drives and even different software.

I finally realized what great frisbees these things are. Cheer up people: THEY ARE GREAT FUN! So grab your spindle, go outside, and start chucking these things at your neighbor's annoying dog. =D

I have been using these to backup data with a Roland VS-2400CD recorder which uses 1 to 4x media.

When it came time to restore the data, I found out that EVERY SINGLE DISC I HAD BACKED UP ON THIS MEDIA WAS UNREADABLE ! I have over 30 of them.

I tried them in the computer, with a Nero disc quality test, which came to 0. Surface scan showed between 10 and 30% defect accross all discs !

I also tried burning them on the computer, and the results were no better.

These are the discs made by InfoDisc . As mentioned in another review, they are the worst. Sure, you can write on them, but don't count on being able to read when you need to.

Avoid at all costs !!!

before i can actually burn on any of these cd-rw's i have to do about five "quick erases" on BOTH of my cd-roms (doesn't work if i try it even 20 times on just one cd-rom), before that - gives plenty of writing errors.. plus - half of the cd-roms i tried to use these cd's on refused to read them.. buy something else..

p.s. "is it live or is it memorex?" the label states.. it is dead and it is memorex..

My computer is unable to read of burn theses disks in my CD-RW drive. Is it my computer or is it Memorex?
