How do I find old files in time machine after clean install of lion? I recently did a clean install, and reloaded my apps instead of migrating because of previous sluggishness. My problem is I can find most of my pictures. Time machine has already back up the new system, so the only thing I can find is that. I am very much hoping I can recover the missing files. please help. I found the old drive, but it says"resource temporarily unavailable"
