MakeMKV Scsi error - Medium ErrorĬommon Scsi error - Medium Error messages are listed below: Ensure that the disc is in good condition with no major scratches or damage that might interfere with the reading process.Ensure that your optical drive has the latest firmware updates.

#Makemkv key install#

You may need to install the libaacs library or similar libraries to handle decryption.

Some discs use AACS (Advanced Access Content System) or BD+ for protection.

#Makemkv key software#

You might need additional software like WinX DVD Ripper Platinum, or AnyDVD to handle the decryption process. MakeMKV is not designed to remove copy protection by itself.

Make sure you are using the right software for decrypting and ripping copy-protected discs.

#Makemkv key update#

Update to the latest version of MakeMKV.

Increase Read retry count in MakeMKV preferences.

Set your computer system back to a date before your free beta key expiration.

Update MakeMKV beta key if you are using its beta.

Run MakeMKV as the administrator on your computer.

The following SCSI error illegal request in MakeMKV is commonly complained by users. MakeMKV SCSI error - ILLEGAL REQUEST: READ OF SCRAMBLED SECTOR WITHOUT AUTHENTICATION NOTE: Installing DASPI kernel extension will fix this problem once and forever. Starting from OS X 10.4.4 Apple doesn't release source code for IOSCSIArchitectureModelFamily driver. If none of the workarounds works for your particular drive, your choice is to use slow direct access mode, change drive, or call Apple and make them fix the bug in their OS. Some drives will ignore the data, some will return an error and some will hang. Similarly to type 1 workaround, MakeMKV will supply a buffer for SEND_KEY command despite specification requiring no buffer. Most drives will ignore the buffer and return zero data but some will hang or behave erratically. MakeMKV will supply a buffer for REPORT_KEY command despite specification requiring no buffer. This will work for drives that use the same AGID slots for Blu-ray and DVD. MakeMKV will invalidate DVD-specific AGID instead of Blu-ray one. In no case will any workaround permanently damage the drive. In the best case a workaround will fix the problem in a worst case a workaround will crash drive's firmware and reset would be required. When MakeMKV detects the bug it tries to use a workaround specified in preferences. The same command for DVD discs is implemented correctly.

#Makemkv key driver#

Per both SCSI MMC and AACS specifications this command shall have no data payload but OS X driver requires non-zero data buffer. Two functions - IOSCSIMultimediaCommandsDevice::REPORT_KEY_V2 and IOSCSIMultimediaCommandsDevice::SEND_KEY_V2 in IOSCSIArchitectureModelFamily / IOSCSIMultimediaCommands / SCSIMultimediaCommands.cpp have the same error that prevents sending INVALIDATE_AGID command to a Blu-ray drive. Apple has been notified about this bug but apparently ignored it. The bug prohibits release of a system resource so in a worst case you'll have to shut down and power on after opening every single Blu-ray disc. The API has a bug in it that prevents its usage without workarounds, and for small subset of drives there is no workaround at all. So, at least in theory, any program can read data and key material from Blu-ray discs without obtaining exclusive disc access and from any capable drive.

#Makemkv key mac os x#

Mac OS X version 10.5 'Leopard' and above support Blu-ray discs and feature API for Blu-ray specific AACS key exchange. A separate rant on this matter can be found here. Mac OS X version 10.4 'Tiger' and below don't provide any Blu-ray API and MakeMKV has to use so-called 'direct access' API that works only with write-capable drives and is significantly slower compared to regular read access.

DASPI kernel extension is included with MakeMKV. Starting with version 1.6.4 MakeMKV introduces DASPI disc access mode that is faster and more stable than 'OS access' mode. NOTE: The text below applies only to 'OS access mode'.
