I have a corrupt RAR but I dont need all the files….

Hoping I can find an answer to my problem here.
I had to back-up my whole PC so I placed all the files I wanted to keep into one folder and then pace them into 3.7GB RAR files, all PART numbers. Well, when I try to extract them, I get “header is corrupt” and CRC errors in some of the rars, I don’t really need all the files so is there a way to just extract the files that are OK without WinRAR cancelling the whole extraction as soon as it reaches an error?
Please suggest some software! As I said, I’m not looking for somthing to repair the archiives, just a tool to keep extracting even when it reaches and error.
Answer #1
Right click the first part,Click on “Extract files…” and enable “keep broken files” then extract.
For future cases you’d be best keeping backups as-is (non-compressed) onto another partition,internal or external hard drive.
Discs are not as reliable,Also,You should stick to quality brands such as Verbatim (Only the made in taiwan ones tho).
Answer #2
On a side point, Taiyo Yuden are the best discs in my opinion, they have been bought out by JVC.
These are the ones I get, never had a coaster.
