CRS326 OS Image corruption - hardware failure?

New out of the box this ran for 6 months or so and one day was unresponsive. Bootloader was unable to find an O/S image to boot. Flashed it again and all was well for 3 months and same thing.

Appears to be a hardware issue perhaps bad flash. As Netinstall formats storage, any clever tricks to format the drive while identifying and taking out of service bad areas?

All I had was a screen capture of the log, the attached log is courtesy of an online OCR site.

Thanks, Jay
