From dde33348e53ecab687a9768bf5262f0b8f79b7f2 Mon Sep 17 00:00:00 2001 From: Anton Altaparmakov Date: Mon, 21 May 2007 09:37:42 +0100 Subject: LDM: Fix for Windows Vista dynamic disks This fixes the LDM driver so that it works with Windows Vista dynamic disks which are subtly different to Windows 2000/XP ones. The patch was needed to get a Vista formatted dynamic disk to be recognized and parsed successfully. Thanks go to Chris Teachworth for the report and testing.
