Have had this code come up on Hardware test  4mem/4/40000000:Oxb7757d98   Rang MAC, given case # they said it was the hard drive (2T) has been in for the service and they said it was software and fixed. They ran Disk Utility and it couldn't repair it then ran Smart Utility, Drive Genius and Disk Warrior ( Idon't have any of these programes and do I really need them if the Mac is working) and it repaired it successfully repairing Disk Permissions.


Brought it home and it has happened again the code above came up. iMac shut itself down, had issues with Disk Permissions but iMac goes to Grey screen and slider then the Grey curtin comes down and says to turn off computer?


When I brought the iMac I only ordered it wit a one terrabyte HD but came with two terrabytes, at first I thought this might be good, but is 2T as reliable as 1T?
