From DIY Photography. Even after an Austrian company has shown that it is a hardware they deny, because they would have return money instead of giving out more defective drives as replacements and doing nothing about lost data.
I have already lost one drive to this and relegated any SanDisk drives I have to media cache duty as if they die oh well.
Honestly after years of loving SanDisk I will never buy another SanDisk and they should have to solve the issue or give refunds.
