/X
Forces the volume to dismount (become inaccessible) prior to conversion if necessary. The
system closes all handles to the volume, which means any open files become inaccessible as well.
Converted drives don??™t always perform as well as drives that you created as NTFS drives from
the outset. The main problem is that the Convert utility may not be able to place the Master File
Table (MFT) in the same location as it would appear on a drive that??™s formatted with NTFS at the
outset. The additional head movement causes the drop in performance. The converted drive security
setup may differ from the original drive as well. Make sure you read the Knowledge Base article
at
http://support.microsoft.com/kb/237399
for additional information about security
changes that can occur as the result of a conversion.
Improving Disk Access Performance with the Defrag Utility
As your hard drive processes files, it becomes fragmented; a file may appear in several segments
on the hard drive. Moving the disk head to read each of these file segments is time consuming and
hurts the performance of your system. Windows provides a graphical interface for defragmenting
your hard drive, but using the command line interface can be more efficient, especially when you
automate the process so that it starts automatically.
