When I first install the Wheezy OS on a Kingston 8GB class 10 SD card, using Win32DiskImager, it works fine, but the second that I try to expand the FileSystem by bringing up the config screen (sudo raspi-config), and expand the FileSystem, i get the message that in the next boot up, it will attempt to resize the FileSystem, but when I boot up it just hangs for ever. I read some blogs that it says this resizing may take some time, well I even let it stay overnight (over 6 hours), but it hangs forever. I tried to repeat this process few times by formatting the disk with my PC (fat32), and run Win32DiskImager again, but the same thing keeps happening. If I don't attempt to resize the FileSystem, everything appears to be working fine, I can install programs, and have no issue at all, but the problems start when I try to resize the FS. I would appreciate some help.
