Hi there
mounting one external NTFS formatted USB HDD on to a Linux Network File server system I got the following message :

[root@gudmundur jim]# mount /dev/sdb2 -t auto -o rw /mnt/DV0
The disk contains an unclean file system (0, 0).
The file system wasn't safely closed on Windows. Fixing.
[root@gudmundur jim]#

If I re-connect the HDD back to a Windows machine is there anything specific I need to do to permanaently fix the HDD as the message re-appears again if I re-connect to the Linux machine.

None of the files appear broken and I can't see any physical HDD errors in the log (Linux) so is there a Windows utility I can run to properly close / clean up any files on the disk.
