Sandisk SSD Dashboard version 126.96.36.199
Running SMART disagnostic short test succeeds with no errors.
Running SMART diagnostic extended test reports only "failed". Progress bar shows 10% then 20%, never got to 30%. Problem is repeatable, including after fresh reboot with no user apps running.
Report generated but cant'd be attached (posting only permits .jgp/.gif/.png)
How do I figure out what is wrong? (System is and had been running fine, no obvious issues.)
Thanks for any pointers.
