Unrestricted Read Speed: Possible, Not Yet Enabled

Post by FredK » Wed Feb 13, 2019 2:24 pm

I found the subject message in some screenshots as a LibreDrive parameter. What does it mean? How to enable it?

My first guess was that the old MediaCodeSpeedEdit (http://ala42.cdfreaks.com/MCSE/) could be able to patch the firmware such that the read speed will be increased ("riplock" protection).

There could be several per-firmware features (or entire firmware itself) labeled "Possible, not yet enabled". This means that the feature is not yet coded - the LibreDrive code is missing (not yet written) for this particular firmware, but it is known how to do it and it is going to be done. You have to do nothing on your part - one day you wake up, get a new SDF, and riplock will be gone from your drive.

"Unrestricted Read Speed" refers to a riplock - the drive artificially slows itself down if it sees certain files on disc. This is different from media speed table.

@mike admin:
Thank you for the explanation and the pleasant perspective to get rid of riplock sooner or later.

I just noticed this when I opened MakeMKV and was curious myself what it meant. Just out of a curiosity, how long of a wait are we likely waiting to have this enabled? I'm assuming that this will allow for much faster ripping? I was looking at the specs for my Blu-Ray drive and under read speeds, it shows it being "6x CAV".

I just noticed though, that my last rip was at 4.5x or 19.5 MB/s. I looked up the speed for 6x and it appears to be about 25.72 MB/s. In the grand scheme of things, that isn't that much faster. My last rip was 26,040.4 MB, and it took about 22.5 minutes to rip. At 6x, theoretically, it would take about 17 minutes, a savings of about 5.5 minutes.

Is there a list or post that contains examples of current production drives where the answer is:
Unrestricted Read Speed: Yes
It would help my buying choices.

One day, hopefully sooner then later, an update will be pushed that will turn this option on for any LibreDrive compatible drive. This is a beauty of uploading runtime in drive memory - you can always make it better. Any compatible drive will get this option.
