Disk 1 unknown not initialized
When western digital shows 'Disk 1 unknown not initialized Unallocated', it means the disk can still be detected with its storage capacity while when the disk shows no size at all stated a more worse damage on this western digital hd.

MBR OR GPT
We would recommend you try MBR at first and then you can convert it to GPT later, or you may select GPT as you wish in the first step when usually GPT is more popular with more abilities for holding data and with better performances.
MBR is more accepted by third party software while GPT is less supported in the market since the later one was not all supported by software developers due to technology update delay.
