Can you post the full model number of that drive?

That may be the notorious “Seagate drive of doom”

Was it the 3TB drive the victims, or the 2TB ones?

Both. These are definitely vulnerable.

They issued a fix midway through the run of the ST2000DM001’s but they didn’t change the model number.

The issue was the head servo, if memory serves. That, combined with the newly built 1TB platters made those drives ripe for destruction.

Am I the only one who can’t read a Seagate model number without misreading it as having DOOM in it, regardless of hiw very good the drives are now.
I guess the catchy click bait nickname worked too well on me, and has stuck

Yeah, that’s why we called them the drives of doom.

But like you said, it was only the run between those models until it was fixed.
Now the drives perform well for the price…
Backblaze being an example of how they do average out to be worth the cheap price, as long as one can afford the redundancy to cover inevitable deaths.
All drives die…

Very true. Unfortunately.
