Time machine data inaccesible
I recently reinstalled the OS (10.6.7) on a 4.5 year old MacBook Pro and restored my data from backup. Having done so, Time Machine then copied the contents of the hard drive back to the backup disk. There is plenty of space, so this isn't a problem. The difficulty is that I can no longer access older archival copies of my data.
The vertical column with the dates in Time Machine recognizes that the backups exist. Time Machine takes me to directories marked:
drwxr-xr-x
but incorrectly claims that they are empty. I cannot access the directories marked:
drwx------
at all. When I look at the content of the disk directly, the inaccessible directories have a filled red circle with a horizontal white line in the middle. From the command line when I try to change to one of the inaccessible directories, it says, for example:
> cd Mail/
Mail/: Permission denied.
> chown -R main Mail
chown: Mail: Permission denied
chown: Mail: Operation not permitted
The directory structure is the same as it was previously since the data on the hard drive were restored from the Time Machine to begin with.
Are there suggestions for how to access the archival data on the Time Machine backup drive?
Thanks for your help.
