Ran Onyx and it said to start disk utility from the install disc for start up. Think this is the cause of my issues I was having with some glitches. But apple instructions say to just click first aid and select your volume. Mine says a couple things like 465.8 GB WDC WD5000 and Macintosh HD... I'm assuming the correct volume is just Macintosh HD right? And then it just says click repair, but which one... repair disk permissions or repair disk? Thanks

The Repair functions of Disk Utility: what's it all about?

Repair Disk verifies and, if problems are found, corrects issues with the directory on a disk or volume.

The directory is analogous to a combined address book and road map to where data is stored on a disk or volume. A volume, also known as a partition, is section of a physical hard disk which, from the perspective of the operating system, works like a separate disk. All hard disks have one or more volumes or partitions.

Repair Disk Permissions verifies and, if problems are found, resets (repairs) the permissions on Apple-originated files and folders (objects), i.e. Mac OS X system-related objects and Apple-provided applications bundled with Mac OS X. This is described in more detail in the AppleCare® Knowledge Base document "About Disk Utility's Repair Disk Permissions feature."

Verification compares the current permissions settings of an Apple-originated object against those specified for that object in its associated installation receipt. Receipts are files saved in the Macintosh HD > Library > Receipts folder, i.e. the /Library/Receipts directory. If the permissions of an object differ from those specified in its associated receipt, its permissions are reset to the values specified in the receipt.

First permissions, then disk.

It does not hurt the disk in any way anyway.
