I have a Western Digital 40 gig hard drive. I installed XP pro on it using the NTFS file system. Is there any way to go back FAT32? DOS will not see NTFS to my knowledge. thanks
Why, exactly, do you want DOS access if you have XP already? In my case, it's because I have a triple-boot system:Windows XP, Win98SE, and Linux. FAT 32 is trivially readable by all three.
It all depends on what you want to do with it, I suppose. NTFS.com provides a series of utilities that can access NTFS from DOS, including a boot floppy . Some utilities are free, some cost money. The site also has good information about the two file systems and their comparisons. In most respects, NTFS has it all over FAT32--no file-size limit, larger hard drives, and higher reliability.
You could set up a FAT32 drive partition of, say, 2 GB and use it to transfer files between OSes, if that's what you're after. Give us a better idea of your intent and we can help further.
