Will not boot from HD
After the spinning soccer ball (did not unfreeze), I pressed the power button to restart and got the flashing folder with?mark. After several reboot attempts including option command PR to zap PRAM, and attempts to do the hardware test (unsuccessful), I booted using a Mountain Lion Install CD. Profile showed "there was an error scanning for Serial-ATA devices". Disk repair found only the optical CD drive. Even tried to restore from my Time Capsule, no luck as it hung up looking for the missing HD. Does this mean my HD is dead? Any hints on how to resurrect this before I buy a replacement HD?
Is this a good question?
