I tried alot way to mount but still failed
[~]# mount -t ntfs-3g /dev/md1 /mnt/nxp
Failed to read bootsector (size=0)
Failed to mount '/dev/md/1': Invalid argument
The device '/dev/md/1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?

And

[/mnt]# mount -t ntfs-3g /dev/md1p1 /mnt/GAMES
ntfs-3g: Failed to access volume '/dev/md1p1': No such file or directory
Please type '/sbin/mount.ntfs-3g --help' for more information.

Where you create raid? it seems all filesystems are NTFS.

Quote:
mount -t ntfs-3g /dev/md1 /mnt/nxp
define partition number

Code:
mount -t ntfs-3g /dev/md1p1 /mnt/nxp
or

Code:
/sbin/mount.ntfs-3g /dev/md1p1 /mnt/nxp

Which distro you are using?

If you create raid array at boot time why it display NTFS file system type?

Can you please elaborate exact scenario?
