Accidentally formatted to HFS on a NTFS USB external disk
Posted: 27 Aug 2012, 03:28
I have a 1 TB USB external hard drive. It was formatted in NTFS and used to store files (about 230 GB on it), non-bootable. Yesterday, I accidentally formatted it to HFS while trying to free 10 GB and install a Mountain Lion bootable disk bought/downloaded from APP Store. I came to this forum while searching on the net and it seems someone had similar experience and was able to recover the lost NTFS partition with helps from here. I tried the test disk and came to this screen
