I assume Bob may have linked you to instructions on how to suppress chkdsk on bootup/restart- or maybe Ed O'Daniels's solution did the same. Anyway, I had same problem on bootup on partition H, a partition on my 80 gig slave. I booted into safe-mode (probably should have booted into command prompt, but I was in Safe-Mode already), opened up a command prompt window by typing cmd in the RUN box, then ENTER. Then at the prompt, I typed:
H: chkdsk /f /r . I hope I have the syntax correct; hopefully, Bob or someone else will correct me if I have it wrong. Anyway, the /f and /r switches- to the best of my recollection from my dos days, was to find and repair bad sectors on my partition H. Poof, the problem went away (prepare for a long scan if you have a slow system.) Strangely, there was no report of anything wrong, but the problem went away. Hope this is of some help.

Conclusion
After command the /f /r in window than retsart, it takes the chhdsk....
It took quite a long time and stayed at 4%.... I can't wait longer & pressed the soft button to reboot, it solved the problem.
Thanks again for everybody!!
