has anyone else encountered an error that part 2 of the RAR is corrupted, when trying to extract the 3.1 UHD MKV? I’ve tried redownloading part 2, and still get the error.
The multipart downloads also include a .SFV file that contains the checksums of each individual multipart RAR. If you use a checksum verification program to open this .SFV file, it will verify if part 2 (or any other part) is truly corrupted or not.
If all parts pass checksum verification, you may be getting this “corrupted” error when something else is wrong, such as using the wrong extraction password. This depends on what extractor program you’re using and on what system.
I fixed it by downloading the latest version of Unarchiver… rather embarrassing.
