Note particularly the last three. Smartctl doesn't know what those are, but
it somehow knows they are failing? With a raw error count of zero, no less?
You don't have a bad SSD Glenn. Apparently the S.M.A.R.T data
structures/attributes for SSD have yet to be standardized as they have been
for mechanical disks. Many of the mechanical disk S.M.A.R.T attributes
don't exist for SSD and vice versa.
Newer versions of the Linux smart tools may fix this problem, or you could
hack up some file tables yourself to get your tools to understand that OCZ
SSD's S.M.A.R.T attributes.
Your SSD is fine. I think the Linux S.M.A.R.T tools aren't up to speed yet
WRT SSDs.
