HELP! I have a Lenovo ThinkPad SL410 Windows 7; my issue is that if I insert a USB flash drive everything works fine; HOWEVER, when I insert an external hard drive it does nothing! It is NOT the disk management setting. I have tried connecting a powered USB hub and it works, hence the ports work IF it is given a power boost but I want to be able to use any of my external hard drives without having to use a USB hub, please help with solution, is there a specific driver? Is there something I might be missing? Thank you all for your help!

try this, have all usb ports empty.
plug a usb flash drive into any port.
go to device manager and expand the usb section.
uninstall the usb driver.
remove the usb flash drive and reinsert.
this should force windows to "install new hardware"
once done try your external harddrive

I'm facing the same issue.
My G470 recognizes USB flash (pen-drivers) but can't recognize any of mines external Hard Drivers (those same EHD works perfectly on other laptops.
