NTFS and external USB hard disk

Archived from groups: microsoft.public.windowsxp.basics (More info?)

I have Win XP Pro SP2
I also have an external Lacie 250GB hard disk I want to store my Virtual PC
files on. But, it is formatted at FAT32 and I can't put a file on there that
is over 4GB. So, I tried to convert the drive to NTFS, but Windows won't let
me do this. It keeps telling me the disk is dirty and to run chkdsk / f.
Which I have done and completes fine finding no problems on the drive. Yet
convert e: /fs:NTFS still does not convert the drive reporting it is dirty.
What is causing this and how do I fix it? I have tons of data on the drive
so I can't re-partition it as I don't want to loose that data. I need to
convert it to NTFS.

Any help appreciated.

Thanks

    Anyone? I've ran chkdsk and no problems, I've defragmented the disk, no
    problems. I've checked the sectors on the disk are all lined up ok, no
    problems. Yet it will still not convert to NTFS reporting that the drive is
    "dirty". No idea what this means. Google search brings up nothing. I've also
    told device manager to run it as performance instead of hot swap, still no
    joy. PLEASE HELP ME!!

    Thanks.

    My thought is that files are in use. In any case, have you tried using the
    Safely Remove Hardware function in the notification area to unmount the
    drive, unplugging, and then plugging back in?

    Using the Safely Remove Hardware function flushes pending writes to the
    drive before closing the handle. I think 'dirty' is referring to a state in
    which the drive is waiting for a signal that no more writes are pending.
    Pardon my faulty vocab here, but that is what I think is going on. When you
    reconnect the drive might be 'clean' again.

    No idea. Have been several posts in the last month about this brand of
    drive (LaCie) so may be something specific to how they are prepared or some
    special extra added by the manufacturer. Suggest checking with their tech
    support.

  6. I had the same problem on a Western Digital 400gb external usb hard drive. The convert command kept giving error drive is dirty. The first time I ran CHKDSK, that gave an error too that the disk is in use etc.

    I unplugged the drive and tried CHKDSK again and this time it ran. There were no errors. After that I again tried CONVERT and it converted successfully.

    Try unplugging and plugging back in these cases and performing CHKDSK /f even if it does not fix anything.
