External hard disk(HHD) showing irregular capacities and partitions I tried to partition my external hard disk on Mac using disk utility.
First I have Erased newly added 2TB HHD with &quot;Mac OS Extended (Journaled)&quot; with &quot;GUID Partition &quot;.
After that I have created three partition
PC - Exfat - 500 GB

Time Machine - APFS (Encrypted) -- 500GB

MAC - APFS -- 1TB

I was trying to use &quot;Time Machine&quot; partition as backup but it was failing and giving error so I have erased HDD again with &quot;Mac OS Extended (Journaled)&quot; with &quot;GUID Partition Map&quot; but It got messed up.


Though I just have 2TB capacity it showing up to 3.5TB in total and irregular partitions ?
I have tried Erase few more time completely but given partitions are not going away.
How to restore to its original state no partition with &quot;Mac OS Extended (Journaled)&quot; having GUID Partitions Map ?
