Thanks a lot for the detailed responses.
I wonder why you didn't have Nero InfoTool, since on Feb. 21 you wrote that you had installed Nero 188.8.131.52b, so Nero InfoTool should have been available via Start| Programs| Ahead Nero| Nero Toolkit.
Although the Autorun status shouldn't matter, for testing you could turn Autorun off as described in S10 of my InCD guide

(the procedure is the same for W2K and XP).
I gather that you used CD-MRW (Mt. Rainier) in both the latest and all previous experiments. Again, it shouldn't matter, but you could try to test the standard non-MRW format, i.e., with the option "Format disc to CD-MRW" unchecked in InCD Page Settings.
In fact I am not sure whether your usage of "formatted to UDF" meant "formatted to CD-MRW", so it might be better to speak about "non-MRW format" and "MRW format".
I have difficulties in understanding your copying procedures. Apparently your burner's drive is called K: (and parenthesized K: gives a smiley as in your post!), so it's better to speak about drive K: or the InCD drive rather than the InCD icon (which normally refers to the systray InCD icon).
You seem to have a folder on one of your drives which contains the three files: PowerChutePersonalEdition.exe, pc523.exe and pcbesetup.exe. What is the name of this folder? The reason for asking is that InCD might have difficulties with long folder names; thus for testing, you could create a folder on your drive C:, say C:\test, copy the three files to this folder (one by one, i.e., don't copy the source folder itself), and then try copying this folder to drive K:.
To check if the freezes occur only when copying pc523.exe and/or pcbesetup.exe, you should try to copy these two files individually (one by one) to K:\ (i.e., the root of drive K: ). Please tell us what happens in detail, because even if you tried this already, your previous description is not clear.
If these individual file copies fail, tell us whether you have FAT or NTFS on the source drive. Namely, NTFS supports additional data streams associated with each file, and if a file with additional data streams is copied to a FAT volume (e.g., your InCD disc), all named data streams and other attributes not supported by FAT are lost, but you should receive an error message, such as "Confirm Stream Loss" described in S17 of my InCD guide. Of course, you should also check whether you have adequate permissions for each file (righ-click each file, choose Properties, Security and your login name).
Yet another possibility is that your difficulties are due to other files hidden in the source directory. To check, make sure that Explorer is set up to show hidden files, or run "dir /ah" in a Command Prompt window in the source directory.
I still don't know if your discs were mounted by InCD after reboots (see S8 in my guide), and how you distinguished between CDFS and UDF. To avoid ambiguities, you should right-click the InCD icon, choose Properties, and report all the relevant entries.
In general, instead of summarizing the results of your experiments, please describe each experiment in detail.
