I have an RGH'ed Xbox 360 kinect 320 GB. I installed FSD3 because there was some errors intercepted on the last FSD (1.02) so updated it to 3. I downloaded some games for my xbox and can still copy extracted iso. I remember the last games that moved are Madagascar 3 and Prototype 2. That was transferred after I installed FSD3. But nowadays, I downloaded CODBO2 and Halo 4. I extracted them and it seems that I cannot copy nor move them to the HDD via usb. It shows "operation failed" after a few transfer of files. I wonder there is something wrong with my console. There are huge space left on the hdd so I do not suspect on the storage.
I extracted the ISOs via xbox360iso extract (latest). Seems fine after extraction. The only fails me is that the transfer operation. I only use "card reader with micro SD (8GB) in it". It operates like a USB dongle though.
