did a great job: Following happened: I have a 1 TB sys disk in my Mac Pro. which is Mountain Lion and all work is done from here. I was suppose to test a Software which runs only on Windows. I inserted an SSD card and installed Marvick on that drive. Then I opened Bootcamp and partitioned the SSD, formatted the Partition "Bootcamp" to NTFS and installed Win 7 on it. Also I downloaded the drivers from the Apple Website and installed those. Everything worked fine, Win 7 is installed, .... but my original 1 TB sys drive does not show up as sys anymore. It says: "System Reserved" and below 109.4 MB. I can not open the drive in OSX, because it is formatted in NTFS. When I look at the Get Info, it says: Capacity: 104.9 MB Available: 79.6 MB Used: 25.3 MB Format: NTFS Only in disk utility, I can see, it is (was) my 1 TB system drive. I was installing WIN 7 on a partition on my SSD drive, not touching the 1 TB sys at all. WIN or Bootcamp has overwritten my Mac SYS with NTFS. What are the possibilities to remove the NTFS Partition to get on my data again?
