After every minute or so of use, I get the SBBOD. Until now, I have been able to restart computer to try to work on problem. But now the computer won't even start. The wheel under the Apple logo just spins. I did hardware test before and it was fine. Now what?
iMac, Mac OS X (10.6.2)
Try a Safe Boot. Hold down Shift at restart and give it much longer to boot. Leave it a while there without opening anything; then restart normally, but don't open anything for a few minutes. Then slowly open applications you use until you see at what point the SBBOD returns.
Check to see how much CPU is being used in Activity Monitor in Utilities.
I can't get it to Safe Boot. I have tried holding down shift key until Apple logo appears, until wheel spins, and even longer. Any thoughts? Thanks much.
The drive may have failed or be failing, or the directory may be severely damaged, or both. But, besides Safe Boot, you can try the other suggestions here: running Repair Disk from the install DVD or fsck from single user mode.
If WZZZ's advice doesn't fix the safe boot issue, Zap the PRAM and Reset the SMC, then try again.
Have been restarting imac due to sbbod but now computer will not restart. Wheel under Apple logo just continues to spin. What do I do now?
