Drive reading as wrong size and can't partition

[whooshbong]

Wonder if anyone could help, as I not sure what questions I need to ask.

When installing High Sierra I decided to go for a complete reinstall so backedup, deleted my bootcamp partition and created bootable usb of High Sierra. Install went fine. I then tried to recreate bootcamp for a windows 7 install. That seemed to be ok until actually installing windows in the installer which said it couldn't because of the wrong file format (NTFS). Following Apple instructions didn't help. Tried a few times by deleting the partition and starting again. Nothing worked. Now however it seems that the drive its self is screwed. I can seem to create any partitions of any kind through High Sierra or through Recovery mode, and the size of the drive has shrunk. However when I click on the option to partition it is reading the drive as 1.11Tb. The drive should be a 1Tb fusion drive. I've tried unmounting and repairing the drive via recovery and also did a fresh install from recovery but nothing seems to be working. Please help or point me in the right direction.

I had some similar problems with high sierra. I think since disk utility was completely upgraded it is not as good as the old disk utility. My problem was that i had a 40 GB partition that i had set aside for windows via bootcamp but then abandoned as i couldn't sort out the bootcamp install but for some reason after i installed high sierra , it had renamed it as the Recovery HD. The recovery partition definitely should not have been as large as 40 GB. In any-case , after futile attempts to sort with disk utility(it just would not delete or resize). i had to use terminal to resolve. IE , open terminal , type 'diskutil list' which showed the drives and sizes , then deleted the faux windows recovery partition and resized the main disk to use all the available space. I'm sure you could probably accomplish what you need with diskutil and there are plenty of guides on using it on the web if you google.

Frustrated with the limitations of Disk Manager in Sierra and El Capitan when encountering similar issues I bit the bullet and purchased Paragon's Hard Disk Manager for Mac:

which solved the problem. Unfortunately there's no trial period and it is expensive.
