After upgrade from Vista 64 to Windows 7 64, USB Hard Drive initially works, then at some point all the "folders are empty" and I cannot access files untill I reboot. Then same thing all over again.

My setup was working perfectly fine with Vista 64; I had a 1TB  Seagate Freeagent external hard drive where I had all my pictures, music and movies. These media was monitored by my zune software, windows media player and windows media center, and also shared on my network.

Then I upgraded to Windows 7 64. At first it seemed fine, Windows 7 recognized and external drive, all applications were still monitoring my media from it, and I was able to access the files. But after a couple of minutes of accessing the files, the drive just seems to suddenly go offline. I can still browse the folder structure, but the i don't see any files, and folders are empty. In some folders I see the files (maybe the info was cached) and if I try to access it, I get an error to "check the location of the file" or "file not available". Once I reboot my system, then everything seems back to normal but as soon as I try to access anything, it breaks as before. It fails even more promptly if I try to download something on to the drive.

All the USB drivers seem OK. The external harddrive works normally on my laptop that has a windows 7 32bit, so no problems in the drive itself.
I tried removing all other USB devices (I have 7 USB inputs on and two more on my monitor), I tried changing power options so that USB ports are not automatically shut off by the pc, I tried reinstalling all the hardware drives including the NVIDIA Chipset driver, I even reinstalled windows 7. The issue is still not resolved.

Does anyone know how to resolve this? Any help is much appreciated!
