I plan to keep the full and differential images on separate DVD disks. Therefore I have first create the images on HDD and then transfer them to DVD using any 3rd party burn app. My burn suite is nero 6.0 reloaded. For UDF 2.01 format (the highest supported by TI) it offers following settings in the manual mode: Partition type - physical, virtual, sparable Which one should I use for the purpose my TI recovery CD doesn't have problems to read it ? Have just created a rollback image of my windows installation for recovery if some times my win gets stucked (currently this quite fresh installation without big balast). In such situations it is better to go back to fresh installation via such backup then to repeat the installation. The rollback image was written to DVD+R directly from TI. I realized that TI didn't finalize the disks. In this case I don't plan to place on that DVD any further images, so maybe closing would be good ? May I close this disk from nero ? From my earlier experiences in general CD burning I know it is always optimal to close the disk if no more data will be added. This helps to increase compatibility with available reader devices and applications. I guess TI doesn't close DVD because user may wish to burn there some more images in some time. Isn't it any risk in handling DVD by another applications/OS ? TI 9.0 Home latest build.
