hm... this does theoretically allow you to make more than 4TB of partitions, if you ignore the limit of the extended partitions.

Yeah....
The LBA values are all relative values. I tried it.
But... how does it allow more then 4Tb of partitions?? I mean 4 byte of partition entry is size:
0xFFFFFFFF * 0x200 = 0x1FFFFFFFE00 = 2199023255040 =~ 2Tb
Do I right? and what is the limitation of extended partitions?

If you ignore the limit on type 0x0F or type 0x05 partitions:
Create partition table with one partition of 2TB and an extended one starting at 2tb running for another 2tb
put the same table at the start of the second
put the same table at the start of the third
etc.
If you ignore the limit on the extended one, you'll just have a relative daisy-chain of 2TB partitions.
