Went to do an offline defrag of system files on reboot and it hung just before the login screen. After forcing a shutdown and booting backup Win7 gave me the option to do a restore (which may remove applications in the process...message stated) or to repair. I went with the repair as I the message on the restore option seemed flaky. The repair failed. I submitted the report to MS as that was an option. After rebooting again there was an attempt this time to do the offline defrag but the message went by to fast to read the failure. Looked like it couldn't gain access to the hard disk. Any ideas?
