Superblock options on OS X
Posted: 02 Oct 2016, 09:22
Hi,
My main system is 10.6, but I have a 10.8 install on a 320GB USB drive. I was booted to that to download sierra and create a bootable USB sierra installer. But in the software, I had the 10.6 drive (named MacMini) selected by mistake when I hit create. I hit force quit when I realized what was happening. It's a 100GB partition with 52GB of apps and system etc. Now it only has 5GB on it and it is named "Install macOS Sierra" but Testdisk actually sees it as MacMini, which seems great to me. But I can't seem to recover this.
When I try write partition, it says Partition: Write error.
So I thought maybe I need superblock, but don't want to do the wrong thing.
So what is the difference between [Org. BS ] and [Backup BS]?
Here is what I have on that screen:
Disk /dev/rdisk0 - 256 GB / 238 GiB - 500118192 sectors (RO)
Partition Start End Size in sectors
2 P Mac HFS 409640 197007831 196598192 [MacMini]
Volume header
HFS+ OK
Backup volume header
HFS+ OK
Sectors are not identical.
