macbookpro 10.6.8; 500 GB HD
I'm preparing to upgrade to el capitan. I bought a 1 T ext HD from One World computing. Under Disk Utility its current partition map scheme is master boot record. I want to divide it into 2 unequal partitions - a 400 GB to BU my current configuration via superduper to make a bootable bu I can use if my upgrade runs into a snag. I want a 2nd bootable partition of 600 GB to back up my computer reg w/ superduper after the upgrade. The OWC has a setup program that appeared on the desktop when I first plugged it in. It shows up in Disk Utility as ms dos 32 format and not as a dmg. So I'm going to use DU.
On the partition tab of DU it offers me a choice of Mac os extended journal or mac os extended journal case sensitive. On Finder searches I sometime wish I had the option of a case sensitive search. Does the journaled case sensitive format have any relation to finder searches? Does it have any cons?
I don't see any options to make a partition bootable - you used to have to do that w/ windows. Superduper will make the partition bootable when I choose that option when setting up my backup?
I can have 2 partitions bootable on one HD? When I option start it will offer both partitions as choices?
Partitioning will erase the disk, right?
Can and should I run a HD test on it looking for bad sectors before partitioning or will partitioning do that?
This is probably simple and straightforward - except for maybe the choice of journaled or journaled case sensitive. 8 years in and I'm still windows paranoid.
