Unreadable file segments
 

Each time I boot up my computer, ever since my computer was accidently shut off by the powerswitch, i get a message saying file segment 103252, 103264, 103265, 103266, 103267 unreadable. My computer seems to run fine although it keeps coming up with every startup. Is it possibly to remove those certain file segments or have them recovered because chkdsk doesn't seem to be doing anything about it. It also won't let me defragment. Thanks,

Sounds like you have lost some clusters on your harddrive. Format drive.
