I bought a set of two hard drives, one failed and went into write protect mode. According to Sandisk Customer Support, "Write protection errors occur when a flash drive detects a potential malfunction within itself. The drive enters read-only mode to prevent data loss. There is no way to fix this. To ensure that the problem is with the flash drive and not your computer, we recommend that you plug the USB drive into a different port on your computer. You should also try the drive on another computer if possible." Of the many flash drives I've used over the years, this is the second drive I've failed with, and so has Sandisk. The first one had some bad memory sectors so my linux boot disk won't install.Ironically I bought these discs to replace a bad one.I give it two stars for a drive that still works and fixes the broken one.UPDATE 6/29/18 : Sent back the defective one and got a replacement from Sandisk. I'm trying to burn ISO and I'm surprised! It's back in read-only mode. So it's a 2v2 in which I'm downgraded from 2 stars to 1. I'll eat up the price , only to throw those CDs in the trash.
