OP, repair the disk first, check if the Smart status is OK on the HD.
Smart status says verified.
A failed disk verify in Disk Utility doesn't always mean a failing drive. It usually means that there is data corruption. This corruption is usually caused by a forced shut down. Start up from another drive and repair the main hard drive.
I ran Disk Warrior from CD (I usually have good luck repairing directory from DW)... and got this:
New Directory cannot replace original directory because the original was to severely damaged. It is highly recommended that you backup all of your data from the preview disk.
Comparison of the original and replacement directories could not be
performed because the original directory was too severely damaged. It
is recommended that you preview the replacement directory.
All files found easily.
All errors in the directory structure such as tree depth, header
node, map nodes, node size, node counts, node links, indexes and more
have been repaired.
189812 files had a directory entry with an incorrect flag that was
repaired.
16 files had a directory entry with an incorrect text encoding value
that was repaired.
1 folder had an incorrect item count that was repaired.
Incorrect values in the Volume Information were repaired.
I clicked the details button, and then nothing... Frozen I guess.? Tried clicking preview instead... nothing. Mouse still moved, but nothing was accessible. Finally forced restart and now I don't quite know what to do. ? Should I use the install cd & disk utility to try to repair?
Also, I use time machine for backup to an external HD. Never had to try to restore though. Do I need to do something else before I fool with the directory & disk further.?
