Thank you for your inputs for my problem.
Please to remove my confusion on K'Probe software.
1. Does K's Probe analyze written or blank DVD or both?
2. I have a Sony DDU1621 reader only.
3. I have a Sony 310A a reader and a writter.
4. Will K's Probe work with both?
5. If I need to install flashware which Sony should I flash?
6. Should I just purchase a new LiteOn 48161H?
7. Is LiteOn a reader or writter or both?
If someone can just answer these question the confusion I have on this program will be solved and I can go on to fix the problem.
Again many thanks for yout time. Please forgive me for being so dumb but I am trying to learn. What do I know as I am new to this.
