LDM database

Dear guys from Veritas, will you give me some info about LDM database? We
need that for our partitioning tools. Maybe someone else can help. I wonder
why doing reverse engineering of dmboot.sys instead of asking the vendors :slight_smile:

Because asking the developers would lead you nowhere.

Disk partitioning IOCTLs for Windows XP are documented in the current
Platform SDK (see IOCTL_DISK_CREATE_DISK, IOCTL_DISK_SET_DRIVE_LAYOUT_EX
and IOCTL_DISK_SET_PARTITION_INFO_EX). Don’t know if that’s what you are
looking for.

I’m looking for the database format to be able to partition dyn disks from
dos extender, linux, etc. not only from NT.

Max

Wow… the thing is 350KB. Nearly as large as NT4’s NTFS.SYS
Very strange - software RAID driver with 350KB binary size.

they have debug info in the driver. they prepare debug output carefully, but
the routine which must print debug infos does nothing. so I wonder why so
much effort for preparing debug info in release :slight_smile:
anyway that info can be helpful if the Veritas guys don’t want to help :slight_smile:

Max

The .text section is half of the image anyway.
Very strange. More than 100KB of machine code for a software RAID.
