Q: Onyx says disk needs repair; Disk Utility says disk is okay?
Yesterday, I finally picked up Snow Leopard. Before installing I figured i'd do some maintenance. Ran Onyx. It came back saying the disk needs repair. So, I inserted my Leopard install disk, booted from it and ran utility. Came back with a number of issues; Incorrect number of thread records, invalid volume file count. So, I ran repair and it came back that it was repaired successfully. Ran verify again to check and it came back fine. But now, when I run Onyx, it still gives me the warning that the disk needs to be repaired. I actually went and verified one more time, and again, it came back okay. Then started Onyx again, and still says needs repair. So, I'm stumped. Is the disk fine? Is Onyx wrong? I'm trying to get this sorted before I upgrade to Snow Leopard. Should I just disregard Onyx's warning, since I've verified and reverified, and just run the maintenance? Any help or insight would be appreciated. Thanks in advance.

OnyX is using the same UNIX command as Disk Utility.
As I understand it, the "live verification" process is quite tricky; making sure all the various directories and catalogs are "in sync" while OSX is busily running requires some things to be stopped briefly, and isn't always accurate.
Try it with as little else running as possible. If it shows errors, also try running +*Verify Disk+* via Disk Utility under the same conditions, and see if you get the same results.
But the bottom line is, if +*Repair Disk+* while booted from your Install disc says there aren't any problems, there aren't any problems.
Just be sure that you always use a compatible version of OnyX and Disk Utility; Leopard for Leopard, Snow Leopard for Leopard.
