Any ideas on this...my Imac (2.16 Ghz. running system 10.6.8) has bee having difficulty in starting up (lost of hard drive noise and crawling to start up) lately and I have Drive Genius 3 as a diagnostic tool, so I ran "Repair" and "Verify Permissions" and came up with the message" Permissions Error : ARDAgent. app....I gathered some info on these boards to use the app Pacifist (V 3.0.2), to re-install the ARDAgent and it should clear up the problem...followed the plan, ran Verify Permissions in Drive Genius 3, which said it was repaired...I then ran Verify to confirm and came back with Verify Failed, Invalid Directory Count, should be 38 instead of 39, and should be 47 instead of 45...But am getting the same results when I run Drive Genius 3 which is the Volume is repaired, but the Verify has failed.... A real stumper...any ideas? Also just up graded to Firefox 12.0 which is when the slowdown started to appear...Thanks

iMac, Mac OS X (10.6.8)

    You need to repair the file system on your HD.  See the yellow box in #6 of Using Disk Utility.

    Used Disk Utility, same results, reports it's repaired, then fails the Verify test and shows the same message count should be 38 instead of 39, 47 instead of 45...any other solutions?

    In rare cases, Verify Disk can report spurious errors (it's quite a trick to compare everything while OSX is running).  See Mac OS X: Disk Utility incorrectly reports disk errors on startup volume


    That article doesn't mention Snow Leopard, and reports of the difference are quite unusual here.  I can't recall seeing one in several months. And for it to be consistent is pretty hard to swallow, too.


    Plus, your report of your system crawling and getting noise from the HD seemed to implicate the HD.


    You might want to run this: Intel-based Macs: Using Apple Hardware Test.  Run the Extended tests (that may take an hour or more, depending on how much RAM you have).  Write down any error code(s) it shows.


    You might also want to compare the noises you hear to these: http://datacent.com/hard_drive_sounds.php

    Verify while booted from the startup disk is using "live" verification, which can be inaccurate. Boot again from another volume or the install DVD and try verifying again from there. If it shows the same error, then something is genuinely off. If not, then disregard the results from live verification.


    In addition to Pondini's suggestions, you can check the health of the drive with the free demo of SMART Utility. It runs a pretty exhaustive check and might be more accurate than the Hardware Test, which is not really known for accuracy.
