    I have a PC on my desk, and I created an account on it named exactly as the one on my PowerBook, with full admin permissions. However, I cannot write to the drive when it it mounted. Can anyone explain why this it? The Windows volume is formatted as NTFS.

    I sure can. OS X has "limited" write capabilites to an NTFS volume. It can read it, but (basically) not write to it.

    OS X can write to FAT32/16 volumes.

    Contrary to what the previous posters said, you should indeed be able to write to it. I do this almost every day. Is your Mac user account an admin user?

    Over the network, using samba, no problem.

    On a mounted drive such as an external hard drive? No way. You're not writing to it.

    How are you mounting it, original poster?

    I think you can write to the NTFS partition if the Windows computer "serves" it to the Mac, but not if the Mac mounts it. Macs cannot write to NTFS partitions directly. Basically, in the former setup, the Mac asks the Windows computer to write to the partition, and it does it on behalf of the Mac. That way, the windows computer makes sure the NTFS journal is correct, etc.

    What you want to do is right click the folder(s) you want to share (or the root drive) and edit the sharing tab. At least, that's the way it was up till Win2k. I think it's the same in XP.

    And more importantly HOW are you connecting from the Mac to the PC? If done through networking (sharing) there should be zero problems writing to an NTFS drive from MacOS X. But if you're doing some kind of direct connect thing where the Mac accesses the PC's hard drive as an external drive or something, then you may have problems.

    I gather that the original poster is tying to use the volume over the network, not directly. The local format under Windows shouldn't matter.

    This sounds like a permissions fault.

    XP Home

    Login as an administrator
    Use sharing and security in XP Home by right clicking on the drives icon.

    Click on the message starting ..

    If you understand........

    Tick share this folder on the network.

    Then tick

    Allow network users to change my files.

    XP Pro

    Login as an administrator

    Open my computer
    Go to tools menu
    Click folder options
    Click view
    Scroll down and untick use simple file sharing
    Now right click on the drive that you want to access

    Click sharing and security
    Click permissions
    Click add
    Type in everyone or your mac user account name
    Permissions should be set to full control or manually tick them all.

    Click on security on the tab at the top of the box.
    If the user account everyone or your mac user account is not visible then add it.
    Tick the full control box or manually tick them all. Ticking this box ticks all the others.

    You could also map the drive as a network drive.
