Yes, you and I would think so.
Unfortuneately, not everyone agrees with us.
To give you an Example, we did run into a slightly related issue with Nero BackItUp just a few months back. Where we allowed the Customer to have full control as to where we allowed the customer to change the TEMP directory for Nero BackItUP. The issue was that we had it set to the C:\Windows\Temp directory by default, and before any new backup occured, all files were deleted in the C:\Windows\Temp directory before a new backup occurs. And I mean all files.
The user could select their own temp directory instead of the default one we provided. And some customers did just that. THey selected their C:\ drive as the temp directory. And when they went to do a backup, our software would ask them 3 times if they were sure they wanted all files in the C:\ directory deleted. After the final confirmation, we deleted all files in the C:\ directory. Unfortuneately, this includes the OS and everything else.
We allowed them to have control, we told them what we would do, and we requested confirmation 3 times. But it's still our fault that all their files were deleted from the C:\ drive.
So we had to create a fix so that if a Customer did happen to select the C:\ root directory, that we did not delete any system files, etc.
I know this is extreme and it's not exactly the same issue, but they are related. As the data on the DVDRW or CDRW could be just as critical or even more so.
We could put an option in there so they can choose if they want to erase the CDRW or DVDRW media without prompting. But what if they forget they had set this? Or if you are in a company and one user sets this, and another users is unaware of it and ends up losing vital information.
We have to take all of this into consideration.
But it's not a bad idea to have an option to allow this to be erased by default. Maybe we can bury it so it's not likely to be done by mistake, or something. We have to look at it from all angles and see if the benifit outways the risk.
I will suggest it as a feature non-the-less and let our Engineering Development team decide.
