Dear All, I have installed FC6 ( from five CDs burnt ) in our PE6600 dell computer, which contains 4 CPUs and 16GB RAM. FC4 was installed in this box previously with no any problem. However after FC6 was installed and rebooted, I got the message of "asking for cache data failed, assuming drive cache: write through, reading all physical data, this may take a while..." This process really took very long (after overnight and still continuing)with back screen. Could any one help me with this problem? Many thanks in advance. Liqin
