- TITLE :INF: Using Third-Party Disk Management Utilities in Windows NT
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:

- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1
- - Microsoft Windows NT Advanced Server, version 3.1

-
- Most MS-DOS-based disk management utilities directly access the hard
- disk by calling MS-DOS Interrupt 13, Interrupt 25, and Interrupt 26.
- The disk I/O model in Windows NT prevents direct access to the hard
- disk; an application must call a trusted device driver for access.
- This prevents an application from compromising the integrity any
- robustness of the operating system.
-
- Some utilities may continue to work, at least in part. For example,
- the Xtree disk management utility has two modes: one that writes
- directly to the disk and another that uses the regular MS-DOS file
- access functions. The latter mode works correctly in Windows NT.
-
- If an application attempts to directly access the disk, the MS-DOS
- subsystem displays a message stating that an application attempted to
- issue an illegal call. You then have the option to terminate the
- application or to ignore the call.
