I have a data file that is 4.7 GB in size and I have been trying to burn it onto a DVD-R. I used drag-to-disc and copied the file from my hard drive to the DVD. The problem is that once the file is burned on to the DVD-R the size is 300 MB as opposed to 4.7 GB. I tried this 3 times with new DVD-Rs each time but the same thing happened. Copying the file from the DVD back to my hard drive confirms the file has indeed somehow shrunk to 300 MB.

Can anyone please tell me what is going on?

I have no clue why that would happen.  That is strange.  Try Creator Classic.  Using packet writing software like Drag to Disc, InCD, and DLA is begging for trouble down the line.  It is unreliable, at best.

First, you're never going to get a 4.7 GB file onto a 4.7 GB DVD.   There is some 'overhead' which means that the maximum you're going to get is around 4.3 GB.

Try opening Creator Classic and burn the file with that.   That program has a gauge at the bottom ( make certain that you've selected to burn to a DVD) that will tell you if the file will fit.    

Plus Creator Classic doesn't use 'packet writing' which some people consider unreliable.

Yeah, my file is actually 4.3 GB or thereabouts. It definitely can fit onto a DVD but like I said it shrinks to 300 MB for some reason. I will try creator classic but it would be nice to know why drag-to-disc is behaving so strangely. It is either a bug in the software or something I'm doing wrong.

Also, I wonder why "packet writing" is unreliable once I close the DVD. After all, the filesystem on the DVD is still UDF.

there are many, many, more on this subject, just do a search if you need more info.

That is a pretty bizarre behavior, even for D2D!!!

Even if compression were turned on (a very, very bad idea) there is no algorithm that could possibly go from 4.3gb to 300mb!

Depending on the type of data I would expect 3.9 or 4gb after compression. Then whenever you would copy the file back to a HD, it would be uncompressed.

Now 300mb is about right for the Overhead needed to format a DVD for packet writing…

Since we are dealing with a V7 version, keep in mind that IE7 and or Media Player 11 can wreck V7 programs.

Why are packet writers unreliable? Cannot say for sure, but this is just another entry on the long list of disappointments from those that think they can use it…

I'm not sure what you're referring to, but I did not find an answer to my original question via search which is why I created this thread. The link you sent doesn't even answer my followup question about why packet writing is unreliable if I am just writing one file and close the DVD immediately.

Packet-Writing, whether DirectCD, Drag2Disc, Nero's InCD, Sonic's DLA, etc, tends to be fussy at best (demanding the exact same Opearating System and program Version that wrote it to be readable - if it's in the mood to do so), and can fail for any reason or none at all.

If the idea is to KEEP the data, NEVER format the disc.

I didn't believe that when my software guru warned me, and managed to learn the hard way.  You can too if you want.

I was really trying to get to the bottom of WHY it is shrinking the file. Yes, I am now using CD Copier or whatever it is called, but the shrinking file issues seems more and more like a bug since no one is able to explain why it is happening.

V7 started about 3 years ago and has been out of production for the last 2 years.

During that time no one has ever encountered, or at least reported, the problem you are having…
