Can't erase OS X Mountain Lion 10.8.5 from internal drive
Hello.
For 2 days I've tried everything I could find in this forum, but erasing 10.8.5 from the Fusion drive (3TB)
wasn't possible - my Mac just restarted instead. So I tried to change the partition hoping to find a clue:
I started internet recovery (alt+cmd+R), clicked "Macintosh HD" and the "Partition" tab.
Under "Partition Layout" I couldn't change "Current" (was greyed), but I could click on the [+] button
for splitting the drive space into 2 partitions: "Macintosh HD" + "Macintosh HD 2".
I started the process and the blue progress bar was growing while the following text was displayed:
"Checking catalog file."
"Checking catalog hierarchy."
"Checking extended attributes file."
... and some other lines ("...shrinking...") were displayed so quickly that I couldn't write down everything.
In the end I got the message:
"Partition failed - Partition failed with the error: There is not enough free space
in the Core Storage Logical Volume Group for this operation."
Is this information helpful? How can I make more required space available?
Maybe Terminal could help?
BTW: Where is that space and why is there not enough space (anymore)...?
