I upgraded a Windows 98 machine to 2000, but accidentally didnt select "Yes" to enable large disk support.  How can I do that now that Windows 2000 is installed without formating my drive?  Thanks.

    dont bother your windows 2000 now convert the drive to NTFS (from FAT)

    How to convert FAT to NTFS

    Firstly BACK up your system, this is the correct way to perform the procedure, but always assume its going to fail :0)


    Converting to NTFS Using Convert.exe

    A partition can also be converted after Setup by using Convert.exe. For more information about Convert.exe, after completing Setup, click Start, click Run, type cmd, and then press ENTER. In the command window, type help convert, and then press ENTER.

    It is easy to convert partitions to NTFS. The Setup program makes conversion easy, whether your partitions used FAT, FAT32, or the older version of NTFS. This kind of conversion keeps your files intact (unlike formatting a partition.

    To find out more information about Convert.exe
    After completing Setup, click Start, click Run, type cmd, and then press ENTER.
    In the command window, type help convert and then press ENTER. Information about converting FAT volumes to NTFS is made available.

    To convert a volume to NTFS from the command prompt

    Open Command Prompt. Click Start, point to All Programs, point to Accessories, and then click Command Prompt.
    In the command prompt window, type: convert drive_letter: /fs:ntfs
    For example, typing convert D: /fs:ntfs would format drive D: with the ntfs format. You can convert FAT or FAT32 volumes to NTFS with this command.

    Important  Once you convert a drive or partition to NTFS, you cannot simply convert it back to FAT or FAT32. You will need to reformat the drive or partition which will erase all data, including programs and personal files, on the partition.
