I am completely newbie with the optical drives stuff, so I apologize in advance.
I have burnt a Windows 10 ISO file into a blank DVD, under a Windows 10 PC and an internal Blu-Ray burner (Pioneer BDR-212EBK) with the Windows’ built in tool for ISO DVD burn. Burning took quite a lot of time, like 25 min.
I have burnt the same Windows 10 ISO file under a Mac with an external DVD burner, also with the MacOS built in tool, and this time process has taken 20 minutes.
Does anybody know why an internal optical drive, which is technically faster and supposedly more reliable, burns the same exact ISO file slower than an external optical drive?? Also, and this I found VERY WEIRD, the visible “drawing” in the DVDs surface (you know, the written sectors) look completely different in the Windows burnt DVD and the Mac’s one: the Mac’s one looks normal, while the PC’s one looks… like a few rings superposed.
I would really appreciate any comment. Can the internal optical drive of the PC be faulty or have been tampered to behave strangely? It is brand new. A million thanks in advance!
