Why does this happen?

3. In the miscellaneous options, check "Keep Broken Files".Outcome: Winrar succeeds at extracting the files even if you are given Volume/CRC Failed errors. The extracted files will NOT be corrupted and will work flawlessly. Just ignore the error messages and it will work.Although I'm not 100% sure about this, I believe that this has something to do with faulty memory.Large files such as multi-volume .rar files use alot of memory, or if running at the wrong voltages, can be unstable and perform errors.These errors are reported in Winrar during extraction but don't actually affect the extraction process.So for anyone who's going crazy from downloading and re-downloading "Corrupted Volumes" when the uploader claims that they are working fine, then save yourself the trouble and use this solution to save yourself some bandwidth, time, and grief.
