Hi,

 

Can anyone please give me a clue as to what may be happening with my iMac early 2008.

 

The problem goes in this order:

 

Flash plug in crashes. Plug-in version 11.6.602.171 is installed. (reload keeps working)

Browsers crashes (mainly using Firefox 19.0 for work 'cos I have too, but also Safari and Chrome) reset keeps working

System crashes (run Disk utility) it says different things but here is an example....

 

Verifying volume “JBH iMac”

Checking file systemPerforming live verification.

Checking Journaled HFS Plus volume.

Checking extents overflow file.

Checking catalog file.

Invalid extent entry

Incorrect size for file WScbb6b82af5544594822510a94ae8d65-7c1ea.html

(It should be 8192 instead of 1099511634962)

Checking multi-linked files.

Checking catalog hierarchy.

Checking extended attributes file.

Checking volume bitmap.

Checking volume information.

The volume JBH iMac was found corrupt and needs to be repaired.

Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.

Checking catalog file.

Checking multi-linked files.

Checking catalog hierarchy.

The volume JBH iMac could not be verified completely.

Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.

 

Repair with disk utility, and the problems start again.........

 

I have installed a clean system (twice) to no avail, everything is updated to the latest version.

 

I am thinking that the HD is beginning to fail, can anyone please advise?

 

 

Thanks a lot for your thoughts. 

 

 

Finest,

iMac (20-inch Early 2008), OS X Mountain Lion (10.8.2), 2.4 GHz Intel Core 2 duo 3GB Ram

    Check the S.M.A.R.T. status of the HD in Disk Utility, if it's not verified then it's failing. Backup IMMEDIATELY and plan to replace the HD. Also run DU from the Restore Partition of Mountain Lion and run Repair Disk, if any errors appear after running it 2 times get the HD replaced. Finally run Apple Hardware Test in EXTENDED MODE at least 2-3 times in succession, if any errors appear immediately take the machine in for repair.

    I suspect either failed RAM or a Dimm needs re-seating. Remove RAM and reseat.

    If you do find your HD is failing under S.M.A.R.T. status you might consider a SSD instead of a regular platter drive. I have the 2.66.model of the same year and my SSD has given my old platform new legs. It is fast and responsive and all my data/storage is now on an external Firewire drive in a hot swappable cradle. By installing a SSD you will decrease the internal temps of the system and probably extend the life of the system. If it were my system I would put 6GB of RAM into it with a 240GB SSD. You can only get a 1.5 Gbs Link Speed but it is so much of an improvement over the HD you will not be looking for a newer/faster model. Mine rocks!!!!
