XP dislikes MiB alignment

While I'm sure about my observations, with a different disk on a different southbridge the same operation ran smoothly, so I don't know what to think.

Let's call that voodoo, and let's go on [1].

[1] I won't discuss how not only a different southbridge and disk can change results, but also the phase of the moon or a concurring solar storm may have affected the results of the experiment.

YOOOO BlackMagic Controlling with vodoo

I have observed a problem with GParted that it will set the Partition Types of some Primary Partitions to CHS values rather than LBA values even when above the 8GB limit for CHS.
New Operating Systems don't seem to care. DOS and 9x definitely do. XP i'm not sure.
It is possible to create Primary and Logical Partitions that meet both the Cylinder and 1MB alignments. I already have done so for my Windows 10 experiments.

Just in case/for the record, there is a known "issue" with bootsector code in 2K/XP (and likely as well in later OS), the bootsector code uses CHS and in some cases with non-matching geometry values it fails to boot, it is easy to patch it however so that only LBA is used, 2K and XP AFAIK actually only uses LBA as soon as booted:

*Almost* the same thing you describe for GParted happens with Windows Format.com (but only for partition that can be actually accessed through CHS):

And now - for no apparent reason if not a shameless plug  - a modified NTFS first sector capable - hopefully - of acting also as MBR:

Yet another shameless plug (the patcher for that issue)...
