Hot Swap SATA Not Mounting

Here's a weird one...
I just built a new rig using an i7-4770k in an ASUS Z87-Pro motherboard.
I wanted two SATA ports to be available as eSATA using SATA>eSATA adapters, so I configured 2 ports (from the Intel Z87 controller) as AHCI and enabled hot plugging in the bios. After wrestling with things a bit, I also removed the Intel Rapid Storage Technology driver, since it apparently interferes with hot swapping drives. In any case, at this point, when I have a drive attached to either port (using a Thermaltake BlackX eSATA drive dock), I do get the tray icon and the option to "Safely Remove Hardware". Clicking that option does dismount the drive, so everything appears to be working in that regard. The problem is that when I plug in a new drive, the system doesn't mount it or even acknowledge that a new drive has been attached. The only way to mount the new drive seems to be to reboot the system with the new drive attached, which really defeats the purpose of hot swapping.
Any ideas why the system isn't mounting the new drives?

No luck. I hit "Safely Remove", and the drive disappeared from Disk Management, but when I have it rescan the drives, the one in question does not reappear.

Sorry it took me a while to respond- I tried updating the BIOS, and it totally hosed everything, so I ended up having to reformat my primary drive and install Windows fresh.
In any case, yes, I did try unplugging it. In fact, I just plugged it in for the first time since the reformat and the system didn't recognize/mount it, but when I rebooted with the drive plugged in and turned on, it mounted fine!

I've got similar HW/OS and the same problem. If you go to Device Manager and select Action->Scan for hardware changes, it will find the new drive and mount it.

Don't know why Windows 7 doesn't do it automatically, though. But at least you can get it mounted without rebooting. SATA hot swap bays are cool, much better than external enclosures, which I was using before.

Nope. Neither scanning in Disk Management nor Device Manager has any effect.
I'm positive it isn't an issue in Windows, as my previous computer (also running Win7 x64, just like this one only on older hardware) would mount drives automatically as soon as they were plugged in. Therefore, this almost has to be a driver/configuration issue and not a problem with Windows itself.
