This is a rare bug that I was unable to re-create. However, here are the details.

From the console run: c:>udefrag -o c:
After 6 hours of defrag overnight, the machine rebooted.

Issues

The hard disk started making clicking noises and could not boot into windows.
Powering off the machine and turning it back on did not allow the machine to boot. Clicking noises came from the hard disk.
Unplugging the machine and the power supply and plugging it back in did not allow the machine to boot.
Vista Repair CD was unable to detect the hard drive.
BIOS was able to detect the hard drive after 2nd power off and power on resets.

Fix

Switching the SATA cable from port 3 to port 1 allowed the hard drive to function normally and boot into windows.
On boot, UltraDefrag reported about 10GB worth of data was missing. i.e. before 198 GB free, after boot 205 GB free.
Hard Disk was still fragmented on boot.

Machine Specs

ST3320613AS Barracuda 7200.11 SATA 3Gb/s 320-GB Hard Drive

Forgot to mention, according to the SMART data, hard disk has been running for a total lifetime of 98 hours

Also forgot to mention, using version 4.3.0 of UltraDefrag.

Did you disable your Anti Virus software before starting the defragmentation, since not doing so results in a race condition between the two.

The system drive is best defragmented at boot or in safe mode, because only then there is not much going on.

To get your lost files back, open a command prompt and run "CHKDSK C: /R /F /V", which will restore lost files on next boot.
Make sure that let this run over night too, since it takes quite long.

The issue you have reported cannot be caused by UltraDefrag since it moves files on disk through single Windows API call FSCTL_MOVE_FILE. The program never changes disk structure directly and never tries to change everything else related to hard drives.

So, your crash was caused either by hardware fault or by conflicting drivers.
