corrupted partition table, need help fixing

Hello (Loner T),


I have an issue with my partition table and need to rebuild it. Would you please assist ?


Output of: 


sudo gdisk /dev/disk0




GPT fdisk (gdisk) version 1.0.4




Warning: Devices opened with shared lock will not have their


partition table automatically reloaded!


Partition table scan:


  MBR: protective


  BSD: not present


  APM: not present


  GPT: present




Found valid GPT with protective MBR; using GPT.




Command (? for help): P




Disk /dev/disk0: 490234752 sectors, 233.8 GiB


Sector size (logical): 512 bytes


Disk identifier (GUID): 57ECCA5D-3ED3-4ECC-B8F8-568B5DF9C6D0


Partition table holds up to 128 entries


Main partition table begins at sector 2 and ends at sector 33


First usable sector is 34, last usable sector is 490234718


Partitions will be aligned on 8-sector boundaries


Total free space is 4035 sectors (2.0 MiB)
