Woops I think i just bought the wrong hard drive.

 

I figured I'd get a portable USB drive for a system clone.

 

I thought it'd be nice when the tornado warning siren goes off or whatever to be able to just pop this drive in my pocket and dash for the shelter.

 

But NOOooOOooo, after cloning to it (using SuperDuper!), it doesn't show up at all in startup disk preferences or startup manager.

 

Am I thoroughly hosed, and need to just get an internal drive for cloning?

 

This is the drive in question BTW :

    Do this:

     

    Erase and Install Snow Leopard

     

    1. Boot from your Snow LeopardInstaller Disc. After the installer loads select your language and click on the Continue button.  When the menu bar appears select Disk Utility from the Utilities menu.

     

    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.

     

    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.

     

    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.

     

    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.

     

    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

     

    7. When formatting is complete quit DU and return to the installer. Install Snow Leopard.

     

    8. Download and install Mac OS X 10.6.8 Update Combo v1.1

    I maybe should've mentioned that other than getting it to show up as a startup disk, I can access this hard drive fine, and the apps etc. installed on it during cloning work as expected.

    Also not sure how erasing and installing Snow Leopard would help, as I'm using SuperDuper! to clone to this USB drive from my main drive, with all it's critical 3rd party software installs and authorizations, and the cloning process would just erase everything including any Snow Leopard previously installed on this USB clone.....

    You had to erase the drive in order to use it on a Mac (it comes formatted in NTFS for Windows). Did you partition it, using a GUID Partition Table (under Options). It needs that to boot on an Intel-based Mac, which the Mac Pro is.
