i recently was hit on my bicycle and broke the screen on my new macbook. i have replaced the screen and now when i turn on the computer i get a white screen with the apple symbol, it stays on for about a minute then shuts off. i have put in the OS X start up disk and run the disk utility. i ran the verify disk and came up with the following: checking journaled hfs plus volume checking extents overflow flie invalid leaf record count (it should be 92 instead of 90)checking catalog file incorrect block count for file com.apple.audio.devicesettings.plist incorrect block count for file com.apple.audio.systemsettings.plist incorrect block count for file com.apple.bezelservices.plist invalid sibling link volume check failed error:filesystem verify or repair failed. before i replaced the screen i had a friend check out the hard drive to make sure it was ok. he hooked it up to and external drive reader and was able to access my drive and said everything looked fine. what do i do?
