  1. When I contacted SanDisk support they told me I probably had a “counterfeit” flash drive. They INSISTED I send a copy of my receipt to show where I purchased it (it was WalMart) instead of helping me fix the problem. It was NOT a counterfeit product & I will never buy this brand again. They NEVER did help me fix the problem. I bought in a multi pack & paid extra because it seemed to have higher storage & safety features. That was money down the drain! Will never buy this brand again.
