They generally disappeared completely, no longer being readable. Spinners die much more gracefully with an easier disk recovery.
That's a weird thing to say. In a datacenter you want your disks to be fail-fast. I.e. you want them to drop out of the array early and cleanly.
Nobody "recovers" harddrives in a datacenter, you just swap them.
The worst failure-mode (that is still way too commonly seen) is that of the "lame drive" that grows bad sectors, predictive failures and all that jazz over time, causing bus-resets, confused controllers and bringing the whole array to a crawl until a human steps in.
That said, my experience with SSDs in that regard isn't too good either. I've seen them fail cleanly but I've also seen a single failing Vertex lock up a LSI-controller hard...
