eSata MyBook problems in Windows 7 Ultimate

Whenever I try to access my eSata HDD in Windows 7 it causes explorer.exe to eat up all my ram. I have tried a couple different copies of Windows 7 and it doesn’t seem to matter. At first I thought it was some of the registry tweaks and various other tweaks, but there is no problem on my Vista Ultimate machine and it has the exact same tweaks.

:sad:I’m at a loss right now trying to figure this out, does anybody have any suggestions?

Edit: Everything works perfectly fine over FW or USB, no problems what so ever, the eSata cable is brand new and works fine in Vista, and mobo eSata driver is up to date also.
