drive constantly loses formatting

Yeah, but you don’t bother telling people the whole story, from those other forums. You neglect to mention that you’ve had this drive for YEARS, and have been running a full-bore Linux distro from it. Including home, swap, and boot. What you HAVE been told (repeatedly) is that the number of read/write cycles it’s been through, along with DOZENS of formats, has led it to have problems. 

THIS is why your drive is failing and having errors, because you trashed it by being stupid. If I drive my car into a tree, I shouldn’t complain to Chevy that it’s not working right and has dents. 

The real “problem” is you and how you’re using the equipment. And SanDisk can’t help with that.
