DOCUMENT:Q231756 10-AUG-2001 [winnt] TITLE :The Convert.exe Tool Uses 512-Byte Clusters PRODUCT :Microsoft Windows NT PROD/VER:winnt:4.0 OPER/SYS: KEYWORDS:kbtool ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you use the Convert.exe tool to convert a partition from a FAT file system to an NTFS file system, the NTFS partition uses 512-byte clusters. CAUSE ===== This behavior is by design. MORE INFORMATION ================ The Convert.exe tool uses the default cluster size of 512 bytes. Using a smaller cluster size allows more efficient use of space on the hard disk and greater probability that the Convert.exe tool has sufficient disk space to perform the conversion. To change the cluster size, use the /a switch with the Format utility to specify the desired cluster size. For information about default cluster sizes, please see the following article in the Microsoft Knowledge Base: Q140365 Default Cluster Size for FAT and NTFS Additional query words: utility sector fat32 convert.exe ====================================================================== Keywords : kbtool Technology : kbWinNTsearch kbWinNTWsearch kbWinNTW400 kbWinNTW400search kbWinNT400search kbWinNTSsearch kbWinNTS400search kbWinNTS400 Version : winnt:4.0 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
