Note: There will be no fix for "not supported" configurations in future.
Most hardware devices have firmware, hidden software that is an OS of its own.
Like all software, it's imperfect and needs upgrades.
One user who contacted Seagate customer support was told that only drives manufactured in December need to be updated, and their drive, manufactured in October, failed after update because of this.
No indication is given on the knowledge base article that the date of manufacture was important, only a list of affected models and firmware.
Seagate is working with customers to expedite a remedy.”For those of you who had problems, did the new update bring your drives back to life? How did you recover data from a barely working drive?
