Your issue is with the file system on your hard drive. And your problem usually means your hard drive is starting to fail so backups become your friend very quickly. This problem can also be caused by other problems, like hooking up external hard drives and not unmounting them correctly. In which case the hard drive is just fine, its only a damaged filesystem which requires cleaning up</div><div><br><blockquote type="cite"><div dir="ltr"><div>> They system then will reset and then you can again enter single user mode.

The command fsck is issued from a shell and means 'File System Check'. This runs a UNIX utility which checks out the filesystem on your hard drive. The option -y tells fsck to not query you for a yes/no response, but assume 'yes' for all queries. This fsck command also calls fsck_hfs, which is a more specific checking utility. But if fsck_hfs fails for some reason you might not really know why. If your error persist it would be worth your while to try fsck_hfs specifically.</div><div><br></div><div>For all utilities you can open Terminal and type "man <command>" to learn more.</div><div><br></div><div>Did you resolve your problem?</div><div><br></div><div>Kristen</div><div><br></div><br></body></html>
