I just checked my ssd 850 health report from hd tune and crystal disk info and I found a problem here is a screen shot attached. Please advise what is this problem and how to solve ?
It's normal for a drive to have error'd blocks with enough writing. I'm not sure when the expected writes before blocks start poofing is for pretty much any SSD offhand but there usually is a 'rating' for them somewhere. I'm not in a position where I can look it up right now.
Anyway, I'll at least explain what's going on. The drive failed to erase 3 blocks because they either have a defect or have gone through too many erase/write cycles (this isn't mutually exclusive, some blocks will erase more than others unless there is an erase count limit specified by the vendor, I don't think Samsung does that). The drive then marks them as "bad" and allocates a reserve block. You can see that it is now using 3 of the spare blocks. This is normal on every SSD and is part of its write leveling. The times to worry about this is if your SSD is increasing this count quickly, if you run out of spare blocks, or you start hitting crashes and blue screens. I don't see a 'spare block remaining' count in the SMART options so it's hard to gauge how bad this is. With that large of a write count, it's likely it just had to reallocate some blocks. It isn't *necessarily* dying, but it is *at least* starting the process of getting kinda old.
If you're worried about it I'd contact Samsung and ask for more details. It's *probably* not a problem. If 3 bad blocks is a problem on an 850 they will probably honor the warranty.
