making external hard drive bootable with SuperDuper

[dnanian]

Hi, mustangpcc. I'm not quite sure what you mean by "lost the option to designate the drive as bootable". All options in the registered version are "shown" in the unregistered version, and we wouldn't take anything away. All backups are made bootable if it's possible to do so.

I'm not sure what you mean by "wanted you to perform another backup", or that it wanted to force erasure. Smart Update doesn't indicate that work will be erased: it indicates that the end result of the backup is the same as erasing (but the technique is different).

So, in sum:

1 - Nothing. All backups that can be made bootable are made bootable.

2 - No, it'll only make the changes necessary.

3 - You can always clean install Tiger after trying an update. But I've not encountered a situation where a clean install was necessary, and I've done a lot of Tiger updates myself and with others.

Hope that helps.
