Hi Everyone
How I thought this was a Nero problem but I Have just uninstalled one version of Nero and replaced with my bros earlier version both original discs.
This problem is also seen on CloneDVD2.
I am now convinced this is a Windows problem.
This is whats happening.
I am unable to copy DVD's with Nero whether they are Video/MP3 files.
Every time I click on copy I receive a warning "disc capacity not big enough".

I had the same problem 4 years ago with totally different equipment and totally different software and I remember wiping the hard drive to solve it.
(which is not the way I want to go)

I have Nero 6 Ultra Edition Version installed ( Now )
I have tried to copy several dvd discs on the fly and it still comes up with the following.

"Data to be written 20,388 MB (21,378,859,008 bytes)
Space available on disc 4,489 MB ( 4,707,319,808 bytes)
please insert larger capacity disc"

If you check the MB above I can see why it will not write
according to this, the disc is only 25% of the capacity required?

Nero sees the source drive as roughly 20gig when I check properties of drive on windows the disc size info is only 3.7gig

I have a clean installation of Windows Pro Corporate edition (US ,UNICODE ) with SP2
installed only a month ago.
Here's a twist, I have just noticed that no matter what disc I try to copy it comes up with the same MB's exactly 20.388 MB which is strange would'nt you say.

Has anyone heard of this before ? Any help would be gratefully appreciated.


P.S I have tried uninstalling the Cd-rom in device manager and re-installing but it still reads 20 gig.
When I check properties of a DVD in the drive in My COMPUTER the disc size is shown correctly only 3.7gig

I posted this earier on cdfreaks with no response, but as I say I dont think its a Nero problem.

Here is a Log File from Nero I have highlighted the device thats causing the problem in RED

I have added a Picture and a Log file from Nero explaining the problem.

Although it may be a windows problem you should still update your Nero to the last version of 6 available. You have gone backwards with your brother's version. Nero's updates actually do help iron out probs. The last version was and is available free.

Thanks Moby
will try that now, by the way the highlight problem device in RED has now
been remapped to CD-rom0 just by disconnecting the ide cable and reconnecting.
it must have changed with a virtual rom device or something like that, I am not sure how it ended up as cdrom3.

Hi Moby
Tried update .....installed fine etc ....but still the same problem any DVD in the source drive
reads 20.388 gig in size. What's all that about eh!
Anyway the state of play is ....I have sent an email to NERO tonight at 5.00pm with loads of pictures for them to look at.
I have also spoken to Samsung about Firmware updates for the DVD Rom drive but thats not a problem as it has worked fine for years. And Nero reconises the DVD model anyway.
I have uninstalled all Nero and All the drives in Device manager.
Swapped the drives on the IDE cables and the Master/slave stuff.
So i am waited for word before I re-install Nero

P.S what is another good program for copying Mp3's on to DVD or general Data copying.
