I know when creating ISO cds in burning software, the user has the choice of ISO Mode 1 or Mode 2. There is no such option in UltraISO. Is the choice of Mode 1/2 dependent on the burning application or the ISO image itself?

I don't normally use Mode 2, but I do know that Mode 2 burning allows you to fit more data on a CD because it reserves less space for error correction.

I was just asking out of interest whether Mode 2 needs to be enabled within the ISO image, or whether Mode 2 is the responsibility of the burning software.

Sorry for any confusion.

In fact, space for error correction of mode2 form1 and mode1 are exactly the same. So this is not a reason for using mode2.

Mode2 Form1 or Mode1 is used for burning an ISO image to a CD-R/RW disc (not DVDs). ISO images have no mode1/mode2 attribute, but raw CD images such as BIN have one of them.

Maybe I was confused about Mode 2-XA or something. Because VCDs use some form of Mode 2 with reduced error correction.

If the Mode attribute is not part of an ISO image, then there is no problem.

Thanks

Hello,

Firstly excellent software thank you...

Rather than starting a new topic about Mode1 vs Mode2 i though i would continue this thread because it does not answer my query which is:

My UltraISO Version is 8.6.5.2140

I have a CD Image which is MODE2/FORM1

When i open the image file and change a file within the image and select "Save" not "Save As" it saves the image as MODE1/FORM1  I need it to save as MODE2/FORM1 is there a setting i need to change/update in order to keep the image as MODE2/FORM1?

Many thanks
