Verifying Disk and Disk Repair ...

Question

Please forgive me, but I know very little about this. I just ran "Verify Disk" on my hard drive in Disk Utility because my firewire devices aren't working and got this message:
Verifying volume “Macintosh HD”
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Illegal name
Illegal name
Checking multi-linked files.

Checking Extended Attributes file.
Checking volume bitmap.
Checking volume information.
The volume The volume osh HD needs to be repaired.
Error: The underlying task reported failure on exit
1 HFS volume checked
Volume needs repair
It won't let me repair the disk, though.

Answer 1

Disk Utility will likely be able to repair this (Disk Warrior is a fine product but you have to buy it, so try the free Apple solution first.)
If you run Disk Utility & click on the "First Aid" tab, please note the last sentence in the onscreen instructions in the window just above the white area where the results of the verify come up.
It explains that to repair your startup drive, you start up from your installer DVD, & run Disk Utility from the Utilities Menu. If you are still uncertain about what this means, click the "?" bubble button in Disk Utility's window & its Help will open to an overview page. Select "Testing and repairing your startup disk" (as it explains) for more detailed info.
