Very exciting question I know but...

I have a dvd+r drive, everytime I write data to a DVD+r it burns perfect, then when I put it back into the computer it says its a blank disc!

I've got the burner set to closed disc sessions so it should be working....I'm using sonic burner, the POS that comes with Dell pcs, but i've made discs in the past with it no prob....anyone shed some light on this? Annoying the hell outta me as this is the 4th disc I've tried....Memorex brand

Try using CDBurnerXP Pro to burn a DVD and see what happens. The Sonic stuff is pure shite.

Possible explanation but by no means absolutely certain is this; (though try what irlrobins said and use other software as well)

Memorex use CMC MAG a lot, CMC MAG are in short crap. The quality of CMC MAG varies so much that you can have perfectly fine discs and awful discs in a batch. Your writer although it can write data to the disc the quality of said disc is so poor that it cannot be read back by the device that just burned it.

You could prove or disprove the theory if you have a NEC or BenQ DVD writer and do a disc quality check on it with Nero CD/DVD Speed and see what comes back. If those drives cant read it either then you know the disc is toast.

If your writer can burn other discs and read them back then I would suspect it is a media issue.

Put a blank disc in download Nero CD/DVD Speed click the disc info tab and see who the media code for the Memorex disc belongs to..

Yeah I checked, twas the disks, bought 5 yesterday, all 5 failed.

Used DVD discs I got - an unknown brand from the pound shop no less - and they worked grand....I'm actually going to write to Memorex, as they is the third time I've gotten a batch of cd's/DVD's that don't work. A few months ago I bought a box of 10 cd-rw and only 1 worked in my NEC drive. I've never had any issues with any other brands...

Honestly it isn't worth your time contacting Memorex I'd be amazed if they even responded they use CMC MAG because it's cheap & nasty but the key part is that its not awful all the time so it lets them get away in some circles without being branded an out-right bad media vendor.

If you want discs of consistent quality then use Verbatim branded ones, you can get cheap discs that are of high quality but you must know what you are looking for and have a decent DVD writer.

If quality is your top priority then look no further than Taiyo Yuden discs, simply the best.

For cheap discs, I use bulkpaq. I've only ever had one bad burn with them and they really are cheap as chips.

The two brands 8t8 recommends are defo the best, but I find them prohibitively expensive.

OP, had the same prob myself a couple of weeks ago, the disk worked on some computers but not all. The problem was that I was using a DVD+R and not all computers can read these, I used DVD-R and it was perfect. The lecturer said that was the problem, maybe its worth a go??

Stick with DVD-R if possible also i find maxell and others always corrupt during burning sooner or later. Get Octron 5 pks from Aldi or LIDL these have never let me down are compatible in just about every dvd player in home cinemas also and to date i have never found a bad disk with them.

8T8

The compatibility issue doesn't really matter that much anymore, only very old hardware cant read DVD+R's combine that with a writer which doesn't write the discs very well either & a DVD drive which although it may support DVD+R isn't a very good reader either you have a recipe for problems.

If you bit set DVD+R's to DVD-ROM you'll often have better luck with drives that cannot read the discs for whatever reasons - quality permitting of course.

Wanted to add something here:

I used my Compaq (I know, I know, shoot me please!) laptop to burn some files to some HP DVDs and afterwards had the same problem as the OP.

Kept trying it in my machine to no avail, however, when I tried again a week later, just on the off-chance, all of a sudden the computer recognises the disk and will play the files for me! Two days later, it says blank disk!!! A week later, yep, it recognises and reads the disk no problem.

I still haven't gotten to the bottom of the problem. I've had no problem playing DVD movies and no problem with CDs, CD-R or CD-RW, just this on-off problem with my own data DVDs. Weird.

I have used Memorex Cd's almost exclusively since getting my PC which has a DVD/CD R/RW +/- burner unlike my old Win 98 crappy thing.

Anyway I must be through I'd say about 40 Cd's and about 20 Dvds both RW and R and have never had a problem.

I also use Sonic Record Now which came with the PC and have never had a problem, either I am lucky or the OP is extremely unlucky. When choosing Dvd I choose -R or -RW always as I support the DVD Forum and it is their format of choice. I have heard from a few people before that DVD+ is much more unreliable than -. Maybe that is the problem

r3nu4l what make is the writer in the machine if you update the firmware it may perform a better write on the media, HP use MCC though not all time which is usually a reliable media.

Download VSO Inspector if your not sure what make writer you have it will tell you.

CD's and DVD's aren't the same and like I said the quality of the CMC MAG that Memorex uses various a lot, it is also depends on the writer and how good it's write strategies are for the CMC MAG code in its firmware. Plus Memorex don't exclusively use CMC MAG either so it may be you never even had one of those discs and as for DVD- more reliable than DVD+ that is rubbish the DVD+ format was created in part because of technical deficiencies in the DVD- format that come companies didn't agree with and didn't want to pay royalties to.

I think what you are mistaking for reliability is it's all about hardware support and whether the device supports it or not and the DVD+ format can change it's booktype to DVD-ROM for devices that don't support it which by now should be few and far between, the same cannot be said for the DVD- format case in point the DVD-R DL format is dead in the water as almost no hardware can read the discs with its DVD-R DL booktype whereas the DVD+R DL discs simply bitset to DVD-ROM and are treated as normal factory pressed dual layer DVD's by DVD players.

Try burning at the slowest speed possible. I know that sounds dumb but it gives me consistantly better results. By doing this I rarely get coasters regardless of what brand of CD or CDVD I use.
