Yes, it looks like the drive is failing, many of those numbers aren't good. The real information is in the "Raw values" column, which gives the values as a hexadecimal number. The visible IDs 05, 07, 0A
, B8, BB
, BC, C4, C5
, C8, C9 should all be zero in the raw values tab. The ones I bolded are not.
If you have no backup of that data at all, I strongly suggest getting a new drive, copying the data to it, full formatting the old one, and then copying the data back to the old one for a backup since it hasn't failed completely yet. I would then suggest removing the old HDD from the computer, and periodically connecting it with a USB HDD dock (so that it is powered off, stored on a shelf most of the time) to update the backup and verify that the HDD still works. Of course, if you have a good backup, just throw this HDD out.
