I use Onyx to run maintenance from time to time. It always asks to check S.M.A.R.T status when first starting up the software. For the first time I ran into this message today:
error detected -9972 while verifying/repairing volume disk0s5 iMac
I have searched everywhere for some info on that with no luck. I repaired permissions using disk utility.. everything looked clean.. nothing to repair. I restarted the computer, and upon starting up Onyx again I received the same message. I'm seeking help in finding out what this error message -9972 means.

Answer 1

OK. I ran disk utility and checked SMART status. It showed unverified or not verified.
Then I did verify disk and here is the message:

I already had my iMac backed up using a program named SuperDuper. So I did the reinstall. It asked if I wanted to erase the disk. I figured ya.. did the install and then ran disk utility again. I lost the message it gave me.. but similarly it stated disk needs repair. I connected the back up drive to my macbook pro and I connected my iMac as a firewire drive. I again used SuperDuper.. this time I used the restore function. I was asked again if I wanted to erase the iMac drive. I said yes..
So far.. everything seems to be in order. The restore worked with no problems. All my settings etc are as they were. The computer seems to be responding more quickly while I am using it. Disk verify shows verified now. Thanks for your help! The only thing now is this folder is open on my desktop every time I boot the computer now: English.lproj Do u know why this may be popping up or what I can do to get rid of it? Thanks again.
