I have a PB 1.33 GHz, and I am running 10.3.7. This morning, I tried to wake it up from sleep, and it seemed to be comatose. I did a hard restart, and it was very slow booting. I managed to login, but it was also very slow loading the desktop, and the hard drive was being much louder than usual. I tried to repair disk permissions, but the system locked up and the application was not responding. I again did a hard reboot; however, this time I got to the white screen with the gray apple, and the system froze. I booted into single user mode and did fsck with the following result - Incorrect block count for system entropy cache (It should be 1 instead of 0) Keys out of order Rebuilding Catalog B-tree The volume could not be repaired. After typing reboot, I got a kernal panic on the white screen with the gray apple. I tried hard rebooting a few more times, and again I am getting kernel panics on the white screen with the gray apple. Is this a system problem or could it be a dying hard drive. Thanks in advance for any help.
