    I wish to format my D drive, but each time I try to do so, whether in normal or safe mode, I am told " I canít format D because the drive is being used by another process or program". I would greatly appreciate it if someone could tell me how to overcome this impasse.

    Thanks and regards,
    Roy

    Answer:
    Dos bootdisk, Windows 7 bootdisk command prompt.

    As a side note, you may want to ensure indexing or system restore is turned off to the drive.
    Or any other program or process that has dibs on the drive in question.

    Also, most any decent bootable partition tool will be able to accomplish the same thing.

    Invest a little time and energy in a well thought out BACKUP regimen and you will have minimal down time, and headache.

    Build your own system; get everything you want and nothing you don't.

    Especially if at any point you've moved any system files or folders over to the D drive. The system will probably recreate them and it won't be a big problem but its not a certain thing. Best to move them back first.

    Try using a tool such as Process Monitor from sysinternals (http://technet.microsoft.com/en-us/s...rnals/bb896645). It can tell you which process has what files open on the D: drive.

    You can also ask yourself is you redirected any files/folders from the C: drive to the D: drive. Things to consider include: temp folder, pagefile, My Documents, My Pictures, My Music.

    Finally, you could use the format command, from the command line, with the /X option - this option forces the volume to dismount. To see the full range of options, open a command prompt and enter:

    Code:
    format /?

    Thanks for all your help. I moved the paging file from D to C drive, and was then able to format D.

    Best wishes for Christmas to all,
    Roy
