How is this an LBA issue?

I'm sorry Consul - but I'm very confused here -
1. you are referring to your system, where you have used MS to create
partitions. Yes, MS uses fdisk, but it's not the same, and MS creates
"damaged" partitions (that's why they're "out of order"). When Debian
(or whatever GNU/Linux you used) created it's partitions it was lumbered
with a DOS extended partition - and yes, they won't align on cylinders -
but thats an MS issue - Debian (or whatever you used) can only work with
the remaining space.
2. your drive has 512B sectors - the OP has 4K sectors
3. you are just listing partitions, not creating them (or did I miss
something?
Is this in reference to the OPs problem? Or are you also having a problem?
NOTE: you are also using CHS - which is OK for MS, which works with both
CHS and sectors (though I struggle to see the relevance to Debian) - but
Debian *only* uses sectors.

That's because MS created the partition....

1024, 2048 or 4096. (Recent kernels know the sector size.

Without actually having a 4K sector hard drive, again, I struggle to
understand the relevance...
The partitioning tool doesn't have to be "4K-aware" [sic] - but if
partitions and sectors don't align (Byte multiples) then several reads
are required, hence the performance loss.
Maybe I'm just tired, or it's a language thing. My apologies if I've
missed something here.
