I tried to make a partition for Windows on my Mac by using Apple's Disk Utility, because bootcamp already showed me that it didn't work for some reason. But now I'm stuck with a 70 gb hard disk, and I'm not capable of accessing the other part of the hard disk (I'm using a MacBook Air with 120 GB SSD).

I kind of expected Disk Utility to let me change the name and everything for this new partition I made (intended for Windows), but for some reason, the only thing that happens is that I can't access the rest of my hard disk anymore and there are no more partitions available.

I hope I've made clear what the problem is, I'm not a native speaker (as you might have noticed) so it's a little hard to write a question about a subject like this.

Here is the output of diskutil list:

/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

  • What kind of "hard disk utilities" did you use to partition your SSD? Apple's Disk Utility? – klanomath Nov 23 '15 at 7:32
  • okay, sorry! I just couldn't really get the codethingy done... I used Apple's Disk Utility indeed, nothing I have done so far has been done by a peer-made program – coen Nov 25 '15 at 5:21
  • The diskutil list output doesn't reflect the observations you made in your question. The output shows the default partition layout of a CoreStorage LVG with one LV( and a Recovery HD) occupying the whole ssd. – klanomath Nov 25 '15 at 7:53

I once had a simillar problem, the disk verification in disk util shown minors errors, but it wasn't able to fix them. As such, I couldn't delete a fat32 partition. Here is what I did :

  • first i booted into safemode. The startup was long as it was fixing errors. (On boot, before startup chime, press and hold Shift)
  • after that i booted in recorvery mode (the same: on boot cmd+r)
  • when the recovery mode shown up, i did load the disk utility and deleted the partition. It worked this way.

However, You Should always do backups of your data, especially if you are messing with partitions
