Booting from External Hard Drive--Stupid Question?

Okay, this is a potentially "stupid question" since I am suffering no problems with it. It may also be a point not worth mooting since I am getting it upgraded.

Current Computer:

MacBook 13" Black 2.1
2.16 GigHz, 4 Gig RAM--yeah . . . I know--OS 10.5.5

Right, this is an upgrade from my infamous Widdle Mac which was a semi-souped up Pismo that ran 10.4.11. I had the data transferred smoothly to the 300 Gig HD of this current computer. I decided to get as part of the deal with my dealer an external hard drive [Ex HD--Ed.] to use as back up.

At that time, I did not know if I wanted to use 10.5. I held off on the Widdle Mac due to speed and wanting to make sure the "bugs" were out. So I got SuperDuper!, "mirrored" my Internal HD [Int-HD--Ed.] . . . happiness!

So I could boot off both. When checking System Preferences--"Start Up Disk" I could see both the Ex-HD and, obviously, the In-HD as options. This worked both ways--whether I booted from the Ex-HD or the In-HD.

Reading HERE I became convinced to try 10.5. Had the disks from my dealer . . . and . . . the System would not recognize my previous system--wanted to "Erase and Instal." Reading through these fora I figured I might have a problem with much of my "stuff" being old PowerPC--even though I updated . . . I think.

Simple solution, methought, I have a mirror. So I backed everything up to the Ext-HD as per usual. I originally planned this if 10.5.5 turned out to not be for me I could easly "go back."

OS 10.5 happily Erased and Installed on my Int-HD--connected to my Ext-HD, the installer happily asked me if I wanted to transfer my previous account.

Great success! Update to 10.5.5 . . . and I have been enjoying it ever since.

There was one weird thing which I mention in similar threads: the Int HD 10.5.5 will not recognize the Ext HD 10.4.11 as a bootable disk IN System Preferences--"Start Up Disk"

But what if you reboot, hold the option key, stupid?

The Ext-HD is there and you can boot off of it. Interestingly, on ITS System Preferences it will show both its Ext-HD and the Int-HD as "bootable" disks.

So why worry? Hence stupid question. The Ext-HD is there to protect data. So long as I can "rescue" my documents and porn . . . should I care?

Okay, after a month enjoying 10.5.5 I decide to back it up to the Ext-HD. Since I have NOT used Time Machine--maybe be part of the issue?--I stuck to SuperDuper!

Voila!

But . . .

Once again, the System Preferences "Start Up Disk" will not list the Ext-HD. Yeeeeeeessssss . . . when you boot up with the "Option" there is the Ext-HD which will happily boot up. Strangely, it will NOT list itself as one of the possible Start Up Disks! Only the Int-HD.

Is this a "thing" about 10.5.5 on an Intel?

Why do you ask that?

I have TechTools and . . . while you can boot off its partition, it is not listed in the "Start Up Disk" list either. That may be because TT has not yet fully, completely, been updated for 10.5.5--coming out in a few weeks.

Who cares? Should I care?

Other than it being "odd" I noticed when I booted from the Ext-HD--just to make sure it works, about everything worked fine but Microsoft Office. This I can understand a bit since MS probably does not want you just "copying" it! Should my Int-HD die tonight, I can obviously replace it with the original disk and there you go!

Now one thing I may try tonight is erasing the Ext-HD--loading on 10.5 straight--rather than having it "copied" as a SuperDuper! update/back-up--and THEN back up and see if that changes anything.

So . . . anything I should be concerned with or, frankly, care about?

Finally, IF this is something "particular" about the MacBooks of 2007, I am getting this replaced with a 2008--2.4 Gig--for a few $$$ more from my dealer. He did not have it available at the time, and he is happy to let me use this provided I do not, obviously, damage it!

. . . or . . . in trying the solution, you can discover that you did not enable journaling on the Ext-HD. . . .




. . . ooops.
