Hello Everyone!

I would like to know if i can install MAC OS X Tiger on an External USB Hardrive?
I'm not sure if it matters but the Hardrive is a Laptop 40-Gig Hardrive.

Thank-You
Bye

You can install it, but I'm not sure if you can boot from it.

Try this:

When you start the Tiger Installer, select your USB hardrive as the destination drive for installation.
If that part works, then try going into System preferences and selecting the USB drive as the startup disk. (By going to the Startup Disk preference pane)

Hope it works!

Nup, Macs can boot from USB. The feature has been in since the PowerMac G4s :)

There is only one problem!
when i did go to do that i it didn't come up on the list (i think!)
But wouldn't have have to install OS 9 then OS X on it?
ok but is what i will do i'll back up all of my 20 gigs of files to my eMac HD then i'll format it with the installer Dvd then i'll add the OS 9 Drivers when partitioning then hopefully it should install?
anyways i'll write back in about 2 hours.
Bye

PS: Thank-You for the very quick replys!

IIRC, the eMac should be able to boot off a USB drive.

I just plugged in my external hard drive using the USB 2 but i doesn't show up as a startup disk.

It works fine when I use Firewire.

Bootable backup using Carbon Copy Cloner.
eMac 1.25 GHz.


edit: USB 2 clarification.

USB booting is one of those semi-yes semi-no things. Depends which Operating system :). Debian and OS 9 can boot using a USB key drive on G3 iMacs with the correct firmware (it was a much advertised feature at the time that they finally got USB booting!).

Afaik though, OS X won't boot over USB, no matter which machine. As for booting on USB 2 macs, that's another matter entirely - I don't know if things changed there or not.

I believe CCC had some issues with 10.3.x and 1.4. I think it is working fine with 1.4.2
I used to use CCC, but now I have switched to Super Duper. Demo version will let you do full clone, but "paid" will also allow incremental back up.

CCC now works on 10.4 (it has been updated), incase none of you guys knew.

AppleCollector,

Use target disk mode.

Turn off the iBook. Connect it to the eMac via a 6 pin to 6 pin firewire cable. Start the iBook with the T key held down. It will then act as a firewire hard disk and show up on the eMac desktop.

Install Tiger.

Disconnect the iBook the same way you would any external drive - choose eject or throw its icon onto the trash can. Then, simply turn it off by holding down the power key for approx. 10 seconds.

Senna,

The machine is a dual USB ibook, and thus has no firewire.. so your suggestion wont work for the poster.

I was going to suggest grab CD media for Tiger and install (but then realised, this wont work either, as I believe Tiger checks for firewire hardware, and when this is not found will drop out saying its not supported).

Um, dual USB iBooks DO have FireWire.

Yep it has firewire, managed to install it via Firewire in Target Disk Mode.

Thankyou to everyone who helped me out!

They do, then why on earth did the poster waste time on USB.. firewire is the best... and target disk mode is the best function on a machine :)

PS. And I will say what I said while doing certification along with everyone else, why on earth can't apple name models in a much nicer fashion.. Dual USB.. what sort of name is that for a model. And yes I dont know all the models well, who could when your not been a fan from day dot :)
