Hi, I need some help repairing errors on my Macbook pro Disk. My Macbook pro has been running slow as of late (spinning rainbow) causing other programs to freeze up. I verify/repaired the disk permissions with no problem until I went to verify/repair disk. The error called "Filesystem verify or repair failed" appeared with the following information: invalid volume count / invalid directory count. This volume needs to be repaired. Question: Is this causing the macbook to run slow? How can I repair this problem? What actions inflicts this problem? ( To prevent this in the future ) Sorry for my grammar errors but I've been working on this repair for hours..thank you in advance.
