My USB drive have 256 bad blocks according to Rufus, and yes it does contain bad blocks since it always give corrupted error message when I try it to install Windows, but running chkdsk on this USB drive shows no error at all, and even though Rufus have the option to check bad block it doesn't have the feature to fix it, how do I fix my USB drive?
The last time I use it a month ago it work fine without any error for installing any OS, I only use it for regular file since then with no problem until now when I want to use it again to reinstall my Windows.
Here is the log.

The flash drive is failing and should be replaced.
The most likely cause of this issue is flash memory that is wearing out. Flash memory has limited endurance and USB flash drives tend to use lower-grade NAND which has lower endurance than the types found in SSDs. See: Can a USB thumb drive "wear out"?
This problem cannot be resolved by the end user. The drive should be replaced as continued use can eventually result in data loss.
