Hi,

Just wondering if any of you can shed some light on an issue that's bothering me. I think I might be missing an old partition from my HDD (a 512gb SSD).

I installed Windows 7 last week under bootcamp, giving it a measly 25gb. This proved to be a massive mistake and I'm certainly paying for it now. Realising the problems this caused I decided to try and extend the partition.

So in OSX I lowered the Mac partition and booted windows, where I used mini tool partition wizard to expand it to 80gb. This, did 'work' but somehow I ended up with less space. In Windows my bootcamp partition was indeed flagged as 80gb BUT it was all instantly used up by seemingly nothing, giving me a remaining 1gb. Something was amiss.

I decided to restart windows, thinking it may clear some temp files or something. As it was shutting down, Windows updates started and got stuck midway through. I hard booted the macbook.

This completely frazzled the 25gb/80gb partition and I was no longer able to boot into Windows. So using this tutorial:http://nerdr.com/tag/fix-bootcamp-partition-not-booting-mac-and-macbook-pro/ I managed to have Windows show up again and booted into it.

As I expected Windows needed repairing. So in the absence of a recovery drive I decided to just wipe the partition and start again.

Back in OSX- I went to Disk Utility just to check the partitions. There was an unidentified gap between OSX and Bootcamp- so I tried to expand OSX back into this space- it wouldn't work. The partition was unsuccessful each time. so I created another OSX partition in this space, which worked fine- no more gaps.

I then started up the bootcamp assistant again to try and remove Windows. The assistant got stuck on re-partitionng. So I went back to Disk Utility and noticed I could use the little minus symbol to remove both Bootcamp and the extra OSX partitions- which I did. I then quit out of the useless bootcamp assistant.

Success! I was now back with no bootcamp, and a full 500gb OSX partition.
SO now I used the Bootcamp assistant again to create 100gb of space for installing windows. Which all went well.

Upon completion I booted into Windows- where the Bootcamp partition is showing as 92gb (8gb is acceptable to be missing in some mysterious windows filesystem) fine.

However, under Windows- my OSX partition (and 'macintosh HD' under My Computer) is showing as 372gb. Confused, I installed Partition Wizard again, which states that the total HD capacity is 465gb, and that OSX is indeed on a 372gb partition.

I rebooted into OSX. In OSX, everything worked out perfectly, my Mac partition is at the correct 400gb and the Bootcamp partition is at 99gb.

Strange then, that in Windows it shows up at 372gb- which possibly accounts for the 25gb parition I messed up when I first installed Windows?

Can you guys boot into Windows 7, if you have it, and tell me if your hard drive is missing 30+gb from the 'Macintosh HD' drive capacity. The partition you allowed OSX?

I'm mainly worried about using up 372gb in OSX and reaching an invisible limit.


Thanks, hope this one isn't too long winded.


Also, an interesting sidenote, the partitions are labelled with start and end LBA's as such:

1: 1 - 409639
2: 409640 - 782476111
3: 782476112 - 783745647
4: 783747072 - 977104895 (Bootcamp)

Note that the numbers follow on from each other, until we reach the end of 3 and start of 4- could this be my missing space?
