Okay. last night I burned an image file of my matlab student version with the Samsung. After making sure the Daemon tools work I burned the iamge file on a TY CD-R. Later when I tried to verify the burning using Nero scan I got error messages when spinning up the drive. I then tried copying the file onto desktop but the drive kept spinning up and down (sounds like it has trouble reading the disc it just burned!). Afterwards the dialogue box shows "59 minutes remaining...". Same things happened when I used another Verbatim AZO media. I tried later on a Liteon CD-ROM it works flawlessly.
I am not sure but I think 830U is another Samsung?
