Error message - incorrect block count

This is a issue with the hard drive or the file system. Can you boot off your os x cd and run disk utility?

 

Excuse me if I am wrong, but have you actually tried what toolbox suggested- booting your system from the OSX installer disk (not the normal boot from your hard disk) and trying to repair from the Disk Utility that is avaiable in the menus at first page of the install process?

It sounds like you were saying that you had tried that when you meant you were booting from your hard drive and trying to repair via your normal Disk Utility. The reason I say this is because in your first post you say the problem is when you boot your iBook, then you mentioned in your second post that this is where the problem came up (indicating that you were booting from the Installer disk as he suggested).

 

Hello,
I am having a similar problem, i decided to run the disk utility when i noticed my mac was freezing sometimes when trying to open programs causing me to perform a hard reboot (which i now know is not good for the hard drive). i tried to verify disk permissions and i got an error that read

Incorrect Block count for file steam_2011_09_18_14_02_16_833.mdmp
(it should be 0 instead of 13)

then followed by a few more lines of text untill it reads

The volume macintosh HD needs to be repaired
Error: Filesystem verify or repair failed

any ideas on what i can do? the computer starts up fine every time its shut down
thanks!
