General questions about drives and 'updating'

Post by dmitche3 »

Just curious.

I've read that drives will update themselves when media is inserted into them and the version of protection, or what ever is lower in the drives firmware, etc. etc.

My question is, is this updated by simply placing the DVD/BluRay into the drive or is it from accessing the media on the discs?
TIA.

LibreDrive and AACS

"One famous “feature” of AACS is a so-called host revocation. It was designed to ensure that only “approved” software can use your drive. Every Blu-ray disc contains a file that has a list of host keys known to be used by "unauthorized" software. This list has a version number. The moment you insert the disc into your drive, the drive checks if the list is newer than the one it knows about, and if it is, the drive re-flashes itself (updates firmware). With LibreDrive mode your drive just became immune to this nonsense."
