you dont need 32k clusters, corruption occurs after 256gb (which is why xbpartitioner uses 32 at that point)

there is no benefit to using 32k clusters on smaller partitions

The 127gb figure is the limit for when your BIOS lacks LBA48 support. If it doesn't support it, then you simply can't "see" any more space on the drive beyond that point, full stop.

In addition to LBA48, your BIOS also needs to support XBP's custom partition tables. Presumably yours does, as you otherwise wouldn't be able to flip between layouts without re-flashing or messing with your mod in some way.

There are multiple versions of the X3, same as the X2. Some older X3 BIOS types aren't compatible with XBP's partitions, but the absolute latest one (whatever that is) should work fine.

When using an X3 BIOS, however, you need to make sure the "Use Saved Partition Table" option in your modchip settings screen is turned on.

If you can't get the BIOSes to agree on how the drive is set up, then make sure you only use ONE such BIOS for accessing it. Odds are you'll quickly run into data loss otherwise. Obviously, you should go with the one that's paying attention to what you do within XBP.
