I don't know why LBA48 would be deprecated. How else should one access
data beyond 128 GiB using BIOS facilities (a common boot loader
requirement)?

The easiest way to detect this is likely to attempt to read data from
either side of the 128 GiB boundary. If both succeed, try bisecting
through the disk until you find something that doesn't correspond to
what the OS sees, and then work out what that boundary might correspond
to.
