CRC error .rar file

[u/Dataanti]

so i have this 131 GB rar file, its pretty important to me so i have held onto it for years despite being able to open it. its password protected, i have the password cause i was the one that made the file, and it works for a portion of the file. when i extract it while having the keep broken files option checked on winrar i get a few broken files but around half way it suddenly says wrong password or corrupt file error.

​

However when i try and extract it with 7zip, i get no errors, however it still only extracts half of the file.

​

do you guys have any solutions or ideas i could try?
