For clarity, the drive that I was referring to was an hard disk drive that was failing, not SSD - I have no position or info on whether it reports SMART data accurately for SSD's. I've found it to be useful for HDDs, but I don't use it for SSDs.I remain unconvinced that Smart Reporter is accurately predicting SSD failures.
On the failing drive above, I dug a bit more, and it was reporting 254 reallocated sectors (which may be the maximum?). Other parameters seemed to flag problems as well.
At any rate, clear to me not worth risking any more data on that drive, given that it coincided with a corrupted/unreadable file and is about six years old.
