2. What blank media are you using? Specify a) brand name b)type (-R, +R, -RW, +RW, RAM, DL, etc.) c)media code, d) capacity/size, e) batch codes/serial codes (often found printed on the inner plastic hub of the blank disc), and f)country (factory information would be great as well, if possible) where the media was made (look on the physical packaging; do not rely on programs to accurately give you this information).
If you don't know how to obtain media codes, you may find the following programs useful:
