Time Machine is Frozen I am running Mac 10.8.5 on a 2008 MacBook Pro, I have my time machine save to an external hard drive. Recently I have been unable to back up my machine because it gets hung up on 'Preparing Back Up' I have seen it chug away for 5 hours preparing that thing, I'm begging to think that it might be broken. I have gone into the external hard drive, and deleted the .inProgress then tried to Back up, didn't work. I have also tried to delete the old back ups, I say tried because while the delete dialogue comes up, they don't go anywhere. I have had to do this in standard finder view because the Starfield freezes when I try to go into that. So my questions are these, what is wrong with my Time Machine? Can it be fixed? Should I just reformat my external hard drive and restart the Time machine?  

EDIT:
The logs for the inProgress files were empty, there is no latest and the last one that worked, from october said:

1: Try this before we proceed:

Unplug your Time Machine backup device
Open Disk Utility (Open Finder &gt; Click Go at Top Menu Bar &gt; Utilities &gt; Disk Utility.app)
Click on your main HDD at the left
Click Repair Disk Permissions
Enter an Administrator Username/Password and Click OK
Once complete, plug in your Time Machine backup device and retry

If this doesn't work, then we need to checkout your logs files (instructions below).

2: How to view your Time Machine log files:
Time Machine keeps a log specific to each backup in the root directory of the backup.
To access its logs, do the following:

Open Terminal (Open Finder &gt; Click Go at Top Menu Bar &gt; Utilities &gt; Terminal.app)
Type cd /Volumes/[Time Machine disk name]/Backups.backupdb/[Machine name]/Latest
Type sudo nano .Backup.log to view the log file

Note: To view the &quot;in progress&quot; logs go into inProgress directories via Terminal you can also see the hidden log files if you type 'ls -al'.
Let us know what these log files say and we can better assist you with your issue.

3: Lets check the system log for the Time Machine's backup process.
I'm certain your issue lies with a single or a couple files that are not behaving nicely.

Open Terminal (Open Finder &gt; Click Go at Top Menu Bar &gt; Utilities &gt; Terminal.app)
Type sudo grep backupd /var/log/system.log
