I have the following:
Western Digital 2 TB HDD (65GB used space)
Seagate 250 GB HDD (with nothing on it)
The 2 TB HDD has Mac OS X 10.6.8 that I need to clone onto the smaller drive in order to use it with a Mac Pro (A1186). I want to shrink the partition on the 2 TB drive via gparted and then use clonezilla to clone that partition along with the boot partition onto the 250 GB HDD. When I open gparted terminal shows an error that says it only supports 512 bytes length sector and gparted shows the partition with a caution exclamation mark that indicates it can not read the contents of the drive. Mounting the drive allows gparted to read the contents and tells me how much used/free space I have but I can't shrink the partition while its mounted. So how do I go about shrinking the partition ensuring both HDDs have the same byte sector size and cloning it to the other drive in order to make it bootable?
Please see images that show gparted with drive unmounted and with the drive mounted.
