Hi, Been struggling with my new HD that I installed a few days ago - after installing the drive I used a clean install and migration assistant. Really hope someone can help with this! The problem is that when I verify the drive in disc utility, it gives me the following feedback with minor variations: "... Checking volume information. Invalid volume file count (It should be 693445 instead of 693120) Invalid volume directory count (It should be 146379 instead of 146186) Invalid volume free block count (It should be 54214500 instead of 54225168) Volume header needs minor repair The volume McMac was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk." I have already tried repairing with disc util from the recovery HD and I have also tried to fix it with DiskWarrior running from an installation on an external HD. When I run these repair tools, they all report that the problem is fixed. And when I boot back into OS X, the disc until usually reports back with no errors initially. But if I use my mac for some time and then run another scan, the error is there again. Maybe I need a new drive, but what strikes me is that everything seems to be running just fine, and I tried to scan for bad blocks with DriveGenius - nothing indicated any errors.. Any ideas?
