So I copied disk.sys and partmgr.sys 5.2.3790.3959 to an XP 32 machine, the original MS disk.sys and partmgr.sys was 5.1.2600.5512. Instead of Disk Management MMC saying "MBR GPT protected", I now see all 16TB of this Seagate HD. The 16 TB drive was formatted to empty from a Win10 box with NTFS on eSATA. SMART says zero reallocated sectors. But, out of curiosity I ran XP 32 "chkdsk E: /r" on the 16 TB NTFS partition. I really want to be sure all 16 TB is addressable, and not magically loose data left and right months later. I am using a ICH9R southbridge Core 2 mobo.
XP32 Chkdsk, is a disaster.

Now I have 0 files on drive, and only ~550 GB free disk space. XP 32 chkdsk really did add 15.5 TB of bad clusters. Ironically the Intel Matrix Raid BIOS config screen says its a ~550 GB drive but I dont have the drive in a RAID config, this 16TB drive never will boot drive. Just extra NAS basically and the tower case has alot of room and is on 24/7. Has anyone else ever run XP 32 chkdsk on a > 2TB GPT drive before?
Is chkdsk logic inside NTFS or some other driver? Are there more files to copy from Server 2003 32? Feels like a disaster to leave this GPT drive forever in an XP 32 box if user error, or my error running chkdsk wipes the data. I'll reboot into my Win10 rescue stick and format this drive again and run chkdsk from Win10. Reports are fuzzy online if ICH9 chipset or the Win32 Intel drivers for ICH9 handle > 2TB at all on any OS.
