Cannot burn a CD-R In Drive D nor CD-RW in drive E despite changing various discs. However can read or play music.

Look in the Device Manager..........

Start | Control Panel | System in classic view | Hardware tab | Device Manager

Click on the (+) next to DVD/CD-ROM drives.  Post the brand and model of the drives.

Please describe how you are trying to write to a disc.  Are you getting an error
message?  

Samsung CD-R/RW SW 252S ( in Drive E)   Error: Drive not accessible, incorrect function.

Samsung DVD-Rom SD 616 E  (in Drive D)  Error: There is no disc in drive. Insert a writable CD into drive

I am using Sonic Burn CD/DVD with record now.

I have deleted and reinstalled these drivers and also deleted and reinstalled the Sonic Burn program.  Still the same response.

Thank you for your interest in this subject.

The SD616E is a DVD-ROM and is not capable of writing to
CD media: it can only read them.

The SW252S is the writing drive.  In My Computer, right-click
the E drive and select Properties.  Then select the Recording tab.
Is the box for Enable CD Recording on this Drive have a checkmark?

Yes it is checked.  The source of files is marked from C drive.

However, I took the time to uncheck, apply, and hit ok.

Then I checked it again, applied and hit ok.

To find out if we are making progress, I tested two ways to get a copied disc.

Good news!!

I now have a drive E Window which I previously did not have.  I can go from My Documents, copy to Drive E Window, and make a copy on disc..

Bad news!!

I still cannot use the Sonic Record Now program which says -a suitable drive is not detected. 

Thanks for all your clues!!   It looks like the problems in Sonic.
