Shouldn't make any difference.
Try ES FIle Explorer and the direct paths from root from my earlier post.
/mnt/usb_storage/
Also try Settings - More - Storage and see if the drive is listed.
If you can't see the storage at all from any app, then it's a hardware problem. Either with the USB storage or H8. I think most likely USB disk isn't formatted correctly but other things to try would be different USB ports on H8, different USB stick, NTFS or EXT format rather than FAT32.
