--- Comment #5 from Andrius Štikonas <andr...@stikonas.eu> ---
Git commit f4cbc64f683c1b9601ed484602105d1d59ebd423 by Andrius Štikonas.
Committed on 01/08/2026 at 11:07.
Pushed by stikonas into branch 'release/26.08'.

Rewrite NTFS updateBootSector code.

Old code was not safe for partition that starts beyond 2 TiB.

Also switch to QDataStream::LittleEndian rather than hand-fixing endianess.
