new SD clone not in start-up disks
Hi all,
About to upgrade to Snow Leopard, so I duped my start up disk to a USB2 disk in case Snow Leopard goes haywire. All of the SD status indicators, including Make Bootable, were green at the end of the process. But when I restarted (for good luck!) and plugged in the USB2 disk, it doesn't appear in the start up disk window. Any ideas? FWIW it was originally a MSDOS FAT disk that I reformatted to HFS+ journaled using Disk Tools. Also, Disk Tools shows the disk partition map scheme as master boot record... I figured SD would take care of all the permissions and other issues so the disk would be a valid start up disk, am I missing something? Thanks in advance! -Chris |
I'm sure it's not partitioned properly: it needs to be repartitioned as GUID. See the Frequently Asked Questions -- Help > Frequently Asked Questions inside SuperDuper.

Excellent, thanks for the quick response!
So, from the FAQ, HFS+ is an overlay on MBR, which is not bootable, gotcha. I don't have an actual disk formatting utility, just Apple's Disk Utility. Do any of the DU options... http://ccaajj.net/Picture1.gif ...use APM or GUID as the underlying partition scheme? GUID is really all I need, running an Intel Mac. Thanks again! -Chris |
You need to go to the partition tab and repartition. Click Options in there to choose the partition scheme.

Perfect, I hadn't noticed the Options button.
Thank you VERY MUCH for probably the best customer support experience I've had in some 15 years of dealing with Mac tech issues! Have a great long Labor Day weekend, -Chris |
