Weird spin drive issue: 3+ mins loading Hearthstone decks!?

You shouldn't have to play Hearthstone to know my issue. I'm just using it as an example. I have two drives:

C: My operating system and misc files.

E: All my games.

I have Hearthstone installed to the E drive. When I launch the game, it's fine, until I load my decks or start a match. It then takes 3+ mins to load. I can hear one of my drives working insanely hard. This seems odd to me, considering Hearthstone is not technically demanding. Both of my drives have plenty of HD space (both ~100 GB free out of ~590 GB total). Once this 3+ minute load phase is complete, I never have to worry, until I quit Hearthstone and re-launch it.

Two questions:

1.) Which drive is the culprit, do you think? The E drive storing the games, or is the game somehow passing commands through my C drive?

2.) How do I fix it, if I can? Should I replace the HDD? Reformat? I already tried reinstalling and defrag, which did nothing.

1) If the game is on the E: Drive, then it will load mostly from that drive. Do other games also have a slower than normal loading times? and the HDD works too much on other games as well?

2) You could first try a "chkdsk /R" on the E: Drive to fix bad sectors, but to be safe I would buy a new drive.

1.) I believe it's only on Hearthstone, although I have noticed when I try to run League of Legends, the network login will timeout the first time and I have to keep logging in until the game lets me on. It's been like this for weeks. I think maybe the client is mistaking my long HDD load time as a network error, so it's timing me out and saying I can't connect to the server.

2.) I will try this now and report back.

The "chkdsk /R" will take about an hour or more.

Another test I just thought of is why don't you install Hearthstone on the C: Drive and see if it does the same thing?

I did the chkdsk on the drive, but it reported no bad sectors and didn't fix anything that I can tell.

I've now installed Hearthstone to the C: and sure enough it loads great, so yea the E: drive is definitely the culprit. Well, I guess that settles it then. I recently acquired an SSD hard drive which I'll be replacing the E: drive with. My biggest concern was isolating which hard drive was the culprit, so I feel better now knowing what to remove.
