I'm having a weird issue. I setup one of the drives of a cMP (4.1) as Time Machine Backup, and set it as encrypted backup (never had tried that and I thought about giving it a try). It did the backup and all went well, until I shut off the mac. Now, it is always asking me for a "disk password" when booting, after I give the password a progress bar appears but it does not complete booting. Is it trying to boot from the Time Machine Backup? Has anybody experienced something like this? Do people use internal disks as TM backups?
