Hi, I'm running OS X Mountain Lion on a Late 2009 iMac. Over the last few days, I have noticed that something has gone horribily wrong with my internal hard disk. The free space on my drive, instead of being at the bottom of the table, is at the top.

I've got no idea how I managed to do this, but I was wondering if anyone knew how to fix it. Running

$ sudo gpt -r -vv show disk0

outputs:

 

gpt show: disk0: mediasize=1000204886016; sectorsize=512; blocks=1953525168

gpt show: disk0: PMBR at sector 0

gpt show: disk0: Pri GPT at sector 1

gpt show: disk0: Sec GPT at sector 1953525167

       start        size  index  contents

           0           1         PMBR

           1           1         Pri GPT header

           2          32         Pri GPT table

  1953525167           1         Sec GPT header

and

$ sudo diskutil list

gives

 

/dev/disk0

   0:      GUID_partition_scheme                        *1.0 TB     disk0

   2:                  Apple_HFS Lion Client             363.9 GB   disk0s3

   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s4

Any help would be appreciated. Thanks
