After XCOPY the NTFS partition on USB drive shown as RAW, Access Denied

I run Windows XP Home, I have an external USB drive Maxtor OneTouch II, 280GB. There are 3 partitions:

70GB FAT32
70GB NTFS [the troublesome]
140GB HFS [used for the Mac]

I ran XCOPY to backup my stuff on XP and it quit on me with an error (I did not write this down as I had not realized there was some problem).

The long story short my NTFS partition became RAW and inaccessible:

Window explorer shows this as 'Local Disk' not the original label:

When I connect my USB drive to the Mac, OS X mounts it and can read the NTFS partition no problem.

Partition Magic shows the partition as NTFS, however the built-in file browser shows it's empty. Disk Management also shows it as NTFS:

Checkdisk finds no problem as well:

Any idea what happened and how I can make this partition working again?
Thanks

 

Why use a DOS program (xcopy) to write to an incompatable NTFS disk? That would not have occurred to me, since you could just mark multiple files in explorer and drag them to the drive as a unit, or put all the files in folders and drag the folders. Think it best at this point to remove the partition and remake it using disk manager in XP, which will also format it any way you like, and save xcopy for writing to the FAT partition.
