Q: HELP! I have 7 partitions, 2 EFI, 2 MacHD, etc.

I have no idea how this happened, but my internal HD has ended up with 7 (yes, seven) partitions, 6 of which are invisible, and several of which are duplicates. Neat trick, I know, and no, no clue how!

 

Specs: iMac 27" Late 2012, running Mavericks 10.9.5. Have tried rebooting into Time Machine (external drive), a CarbonCopy Clone (other external drive) and Recovery Mode, none of these will allow me to re-partition the drive. Here is what Disk Utility shows (with hidden volumes enabled):

Screen Shot 2015-01-29 at 7.49.00 PM.png

When I run diskutil list, the drives appear as follows:

/dev/disk0

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *121.3 GB   disk0

   1:                        EFI EFI                     209.7 MB   disk0s1

   2:          Apple_CoreStorage                         121.0 GB   disk0s2

   3:                 Apple_Boot Boot OS X               134.2 MB   disk0s3

/dev/disk1

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:      GUID_partition_scheme                        *1.0 TB     disk1

   1:                        EFI EFI                     209.7 MB   disk1s1

   2:          Apple_CoreStorage                         999.3 GB   disk1s2

   3:                 Apple_Boot Recovery HD             650.0 MB   disk1s3

/dev/disk2

   #:                       TYPE NAME                    SIZE       IDENTIFIER

   0:                  Apple_HFS Manor                  *1.1 TB     disk2

 

This all started when trying to set up BootCamp, which also threw up a list of 7 volumes, none of which could be used to install Windows.


I am pretty much out of ideas...... Help?

    I see this is getting lots of views and no answers. Eeek!

     

    Is this configuration a normal thing? Am I worried about nothing? Although I still can't re-partition the drive, which I kind of need to do, so....and more ideas on that?

    This is not normal.  You could boot up using command-r and then using Utilities erase your drive, and make one partition then use TM to restore everything.  I had to do that a few weeks ago to fix a similar issue.

    I tried booting into Recovery Mode (command-R) and the options to reformat the drive are greyed out. I can erase the main partition, but I can't re-partition it.  That's the sticky part - I could wipe the whole thing, but no method of booting will allow me to re-partition.....

    Do you have a fusion drive?

    You need to do…

    diskutil cs list

    …in Terminal to show the core storage setup.

     

    Please post that here, it will make it easier to see what you have.

    babowa: Yes, it's a fusion drive, but this structure stills seems wrong to me. Shouldn't I still be able to do a re-partition in Recovery Mode?

    I only had a fusion drive for about a week (a new iMac with multiple power management problems which was returned to the store), but I had a problem first trying to partition it in Disk Utility and then trying to repartition and erase the drive in recovery to be able to return it. I finally managed after several tries - can't remember which step finally worked; try to erase either the entire drive and/or one partition/volume at a time. You can only have 2 partitions on a fusion drive by the way.

     

    FWIW, I got a replacement iMac without a fusion drive because, frankly, I was not impressed as I didn't seem to have control over the drive and there really did not appear to be a speed increase with the SSD.

    Thanks for the tip. I wonder what to do about the oodles of extra hidden partitions? Those seem to be the ones causing trouble. What I'd like to have (eventually) is two partitions; one for Mac OS, and one for BootCamp. But the extra EFIs and such are freaking out the Windows installer.... I have a feeling that the 'extra' hidden drives were created by BootCamp, but I 'reunited' the drive using the BC utility, so it should have corrected for that, I'd think.  Alas...

     

    I'll keep pecking away at it, though....

    I have gotten BootCamp to behave, but I still have an excess of hidden partitions. Except when they're not hidden.

    Because this is what happens when I reboot:

    Screen Shot 2015-02-04 at 11.11.23 AM.png

    'Manor' is the primary internal Mac Boot drive, BootCamp is well, BootCamp, partitioned off the internal drive.  'Archive, 'Warehouse,' and 'Carbon Copy' are all external USB drives. It's the three EFI beasties I'm concerned with! I can understand having one for the internal drive, and maybe one for BootCamp. But three? And should they be showing up like this? They all vanish after a few seconds, but I'm thinking this is not supposed to be a thing? There are still two hidden partitions called 'Macintosh HD' that don't mount on reboot, but are still lurking there.

     

    Any other thoughts? It doesn't SEEM to be a performance issue, and they're not that big, so it's not like it's costing me space I need, but it's weird. I don't like weird when it comes to my Mac; I depend on it too much! LOL But, I remain at a loss.

    AND the plot thickens. Last reboot my Mac started into BootCamp. I figured I'd forgotten to change it back in the Prefs. I went to do that and got this: Screen Shot 2015-02-04 at 6.15.27 PM.png

    Clearly I CAN boot into Mac OS, but I have to do that by shutting down and holding 'Option.' So maybe this IS a serious issue.....

     

    Er, HELP?

    Sorry, this is beyond my realm as I don't use and am not at all familiar with Bootcamp; on top of that, I do not understand why the EFI are showing as they shouldn't be. Hopefully someone will chime in shortly.

    It is possible that the GPT is corrupt on each of the two disks. You have a 1TB Fusion drive (120GB SSD/1TB HDD).

     

    Can you post the output of the following commands?

     

    sudo gpt -vv -r show /dev/disk0

    sudo fdisk /dev/disk0

    sudo gpt -vv -r show /dev/disk1

    sudo fdisk /dev/disk1

     

    These will show the GPT and the MBR on each physical disk.

     

    Was Windows installed using EFI, rather than the traditional Hybrid MBR?

     

    There is also a bug in Disk Utility (and the System Report -> Storage view) where the same storage can be reported more than once.

    Thank you for the reply, LonerT. I will run those commands and post the result here shortly.


    As to the Windows install, I'm not sure what you mean. I used the BootCamp software to partition and restart, but I did have to go back and change the BootCamp partition to NTFS in order to install Windows onto it. Once I had done that, the Windows installer was able to format the partition, and the install went smoothly. But the 'extra' partitions were already there at that point. Other than that, I did not do anything different in the Windows install process.

     

    As to a reporting error, I still have three EFI drives appearing at startup, which doesn't seem to have anything to do with DiskUtility....

     

    Terminal results in a jiffy!
