Another HDD failure?

Win 7 Home Prem from the OEM disk WD Blue 500 GB HDD 4GB RAM NVIDA Graphics card (can find the model if it really matters)

Was suddenly experiencing drastically increased load times (noticed mostly in games like WoT or Total War loading into a fight). Tried repairing the OS without success. Tired a system restore, but out only made things worse (missing parts of the steam library and a failure to download them). Tried a chkdsk and had some sectors that came up with errors (none reported on numerous chkdsk's since). Tried a full reformat and reinstall and got the first batch of updates before an I/O error on restart. Could still intermittently load the OS, but performance still sucked and random system hangs and "connection failures" remained. Replaced the wireless card and tried reinstalling thinking maybe it was that due to the connection failures and thought updates may have been corrupted on download. Needless to say, it didn't work either. Album below are the current errors, not having success getting into the OS at this point.

I had a HDD failure previously where I only got I/O failures on boot and replaced that drive with this one about 2years ago.

I've ordered a SSD for a replacement, but figured I'd check in here to see if anyone more tech savvy had thoughts.
