Note that I am NOT trying to read or write a Blu-ray disc. The problem is not the USB ports as other devices work fine using all of the USB ports on my MBP. The drive itself is only a few months old. File name: samsungbdse-506.exe Version: 2.5.7 File size: 2. My Samsung Portable Blu-ray Writer, SE-506CB/RSBD no longer mounts after I upgraded to El Capitan last week. or invest in a libredrive enabled drive as I have seen in the UHD sub forum. Below you can download samsung bd se-506 driver for Windows. I have noted that MakeMKV seems to get updated periodically so I will need to wait until I see a new release of MakeMKV with release notes: 'Added support for AACS v7 2 (for those poor souls without LibreDrive). This brought it home: 'The latest version of MakeMKV can decode discs with MKBv72 (AACS v72) but cannot get past the revocation table without LibreDrive'. I had read the article on 'What is LibreDrive' before but was not getting that the decoding and having a key to get past the revocation were two different things. The latest version of MakeMKV can decode discs with MKBv72 (AACS v72) but cannot get past the revocation table without LibreDrive. External Blu Ray CD DVD Drive 3D,USB 3.0 Type C Bluray Disc Reader BD CD DVD RW ROM for PC Mac Windows 7 8 10 XP Linxus iMac. What about this statement from MikeAdmin: 'MKBv72 is currently supported on 1.14.5 with latest key updates.' or is that referring to something different? Samsung SE-506CB Blu-ray Writer Slim Portable USB 2.0 External (Black). So I can use up to AACS v70 discs per the MakeMKV 1.14.4 release notes.
