Hello everyone. I have been asked to backup a DVD which appears through WinXP to be a 4.3Gb DVD. However, Nero 6 says it is blank or invalid. I have copied its contents to the HD, but there are over 200,000 files and over 15Gb of data on this disk.
I don't know how this is possible. Is there a simple explanation for this that someone out there knows, or am I slowly going mad ?
Thanks in advance for taking the time to read this.

Sounds like the 4 gigs worth of data was unzipped (uncompressed) when you extracted it to your HDD to give you your 15 gigs. Did you have to use WinZIP, WinRAR or similar to get the files to your HDD?

Hi. It is not zipped or apparently compressed. All the files are sitting there like a normal directory. I have some more details below
From Nero
Total Capacity 4,428MB
Book Type DVD+R
Session01 [4,428MB]
Track01: 0 4,533,760KB, ISO9660/bootable (mode 1)
From the Drive Properties Window
Type: CD Drive
File System: CDFS
Used space: 4,642,254,848 bytes 4.32 GB
Free space 0 bytes 0 bytes
Capacity : 4,642,254,848 bytes 4.32 GB
From the File Properties Window (after selecting all files/folders)
of the DVD
209,831 Files, 5,425 Folders
Type: Multiple Types
Location: All in G:\
Size: 14.6 GB (15,761,940,264 bytes)
Size on disk: 14.8 GB (15,987,015,680 bytes)
Attributes READ-ONLY
From the File Properties Window (after selecting all files/folders)
of the HARD DRIVE COPY
Type: File Folder
Location: \\orak\DRV2(E)
Size: 14.6 GB (15,761,940,264 bytes)
Size on disk: 15.1 GB (16,241,471,488 bytes)
Contains: 209,831 Files, 5,425 Folders
Attributes: None set
So, I have copied all the files off the DVD onto the hard drive and there are all there. So I don't have any answers. When I try to copy the DVD with Nero, it says the disk is blank or invalid.
The only thing I can think of is that because of all the tiny little files on this DVD, they are using a lot more space on the HD because of redundant space allocation. The hard drive is NTFS by the way.
I can always burn it onto 3 normal DVDs. But I am puzzled how someone put this much info on a DVD !!

Why don't you try DVDDecrypter, ISO-> Read, ISO-> Write.

try another program to do a direct copy of the disk..... VSO has a program called blindwrite6:
http://www.vso-software.fr/products/Blindwrite/blindwrite.php
this program will do a direct 1:1 copy of your disk to another disk! It's made for that! check it out.
also Sonic RecordNow will do a direct copy!
and it's funny that Nero can read info on your disk but doesn't recognize your disk? Have you tried Nero Express to do a direct copy? What version of Nero do you have...... the stable version of Nero6 is 6.6.0.18 ...... what do you have?

Hi there. I used DVD-Decrypter in ISO mode and it worked. Perfect backup. Thanks for the assistance. Nero version is 6.3.1.6. Will have to upgrade to 6.3.1.20 or better.
ALthough am still curious how they fit that much on a DVD !!!

ummm... i have no clue on how to burn all that data, but depending on the type of files these are, the answer may be "codecs", which will compress files, and also will decompress files, when they are compressed they are useless, so sometimes Windows (if you have the proper codec) will decompress these files when copied to your harddrive, no software that i know will automatically unzip a file, so that excludes the theory of WinZIP or winrare..
PS: codecs are usually used in media files like music or video, they will extract just the part of the media that is being used, and when it is finished being used will compress it again.
