Can someone please tell me how to format my hard drive with NTFS and a 32K cluster size. I'm wanting to use NTFS but I don't like the default of a 4K cluster size that the XP installation CD uses. I read somewhere that the command would be: format C:/FS:NTFS /A:32 I created an MS-DOS startup disk and copied the format.com to it. I booted up to the floppy and ran the command. It responded that the program cannot be run in MS-DOS mode. Am I doing something wrong?
