files have suddenly gone missing!

[Bebbetufs]

I've been working on an unattended CD for my HTPC setup. I duplicated and renamed my original CD directory, did all changes (didn't touch the I386 folder) and made an ISO. I'm now getting "cannot copy file" messages during install.

After several tries different files are missing every time. The missing files are mostly .dlls!

The last one missing was cryptui.dll. I did a search of all my CD directories, and the file is not there....it is but it is called cryptui.DL_

Has my source gone bad on me, or can I do something to remidy this?

TIA

I deefragmented the drive and did a cold boot. The problem of the missing files is now gone. If anyone else experience troubles with missing files it may be a good idea to defragment the drive before creating the ISO!
