Ext HDD won't show up in windows 7, works in 8.

[DCUK6]

Have a ext HDD that works perfectly in windows 8, it's still named passport so can't see them reformatting it.

 

When you plug it in, it lights up but you don't get a thing in windows, no installing message or anything in device manager. Disk manager does t show it either.

 

Plugged in my stick and it worked fine.

 

Plugged the HDD into a surface tab and it worked fine.

 

I've updated the USB drivers so there aren't any unknown devices listed.

 

Any ideas?

Tried a different port? I have seen occasions when something glitches enabling the drives usb driver and the easiest way to fix it was to switch the port.

Yep, front and back.

Just for kicks, check in Windows 8 what format the disk is in and partition layout in Disk Manager. Windows 7 plays nice with many things but some things just knock it off balance. Also I do know many drives these days are getting firmware updates, so it's worth checking if there is a firmware update too. Won't be the last time a firmware upgrade fixed wacky behavior.
