Q: Partition BootCap on DD 3To Fusion Drive: A methode

In continuation of another post above a bootcamp disk problem, i ask to now how to crate a Bootcamp partition on a 3To. Fusion drive using command on terminal like:

 

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo gpt -vv -r show /dev/disk1

sudo fdisk  /dev/disk0

sudo fdisk /dev/disk1

 

The end of the first thread:

Can't format former Boot Camp partition

 

Thanks.

    Hello Loner,

     

    I look over the page 5 of the other discussion but it was a complicated solution when i have multiples disk problems. Could you, please, give me the operation step by step to put my Fusion drive well?

     

    Second question, what do you think about the solution of an external disk with Windows?

     

    For information:

    1. Boot your iMac using Command+Opt+R (Internet Recovery).

    2. The following steps will erase both the SSD and HDD.


    a. Delete "Macintosh HD" Logical Volume - diskutil cs deleteVolume 7D2AB070-B558-4788-BD0F-ECD835245C2C

    b. Delete "Macintosh HD" Logical Volume Group  - diskutil cs delete FE01F854-51A7-441B-9BBE-B903BA3E5262

    c. Verify using diskutil list that the SSD and HDD still remain disk1 and disk0 for the following steps to work. You can reboot which will renumber disks.

    d. Erase SSD Logical Volume - diskutil eraseDisk jhfs+ SSD disk1

    e. Erase HDD Logical Volume - diskutil eraseDisk jhfs+ HDD disk0

    f. Create a new CoreStorage volume using HDD/SSD (the order of disks is very important). Steps d and e will create an EFI partition, and disk0s2 and disk1s2 will be the 'entire' capacity of the system in HDD and SSD respectively.

     

    diskutil cs create OSX-MacintoshLVG disk1s2 disk0s2

     

    g. Create a 'full' logical volume using the lvUUID generated by step f. Note down the long string from step f.

         diskutil cs createVolume LongStringfromStepF jhfs+ "Macintosh HD" 100%

     

    If you see any error messages, please stop and post back here.

    Ok thanks, just disappointed having to erase again my hard Drive.

    You doesn't answer me, what do you think about the solution of an external disk with Windows?

    You should definitely try it.
