iMac (27-inch, Late 2009). 2.8 GHz Intel Core i7. 8 GB 1067 MHz DDR3. The internal DVD optical drive has been replaced with an SSD that is my start-up drive (OS X 10.3).
I've got a 1 TB WD My Book Studio external USB Drive with 3 equal partitions. One partition has OS X 10.8 on it. Two others are data partitions.
The partition with OS X 10.8 will mount most of the time, but I get a message that it is corrupt. Disk Repair cannot repair it. I was able to copy all information that I need from Downloads, Desktop, Documents, etc to another drive. I want to reformat and install OS X 10.3 on this partition.
I need to make sure that I don't lose the contents of the other two partitions. At the moment I have no available extra space to back-up this data . That will change very soon.
Can I use Disk Utility in Yosemite to reformat just one of three partitions? Is there a safe/safer way to do this?
Thanks in advance,
Cincinnati
