Thank You For Saving Me!
 

I use SuperDuper! to create a daily backup of my primary drive on my Mac Mini. Both drives are external.

This afternoon I inadvertently disconnected my primary drive while it was busy, thinking that I was disconnecting my printer. The drive is now useless.

Fortunately, I simply switched my boot disk to be the backup, and I'm now back in business. I've ordered a new drive to replace the primary. (I also have a second backup that I rotate out periodically.)

I just wanted to say this was the easiest disaster recovery I've ever experienced.

Thanks, SuperDuper!

Ain't it grand?! To be able to flog your system with impunity is liberating, though not necessarily recommended to the masses.

When you say your drive is now useless: Are you sure? What do you mean by useless?

I've tried to erase and partition it with Disk Utility and it just sits there with no progress.

So, it's seeable, at least in DU. Do you have DiskWarrior, or even TechTool Pro?
