Copying Problem

Question

While copying (rather transferring) files from one Hard Disk to another - larger one, I faced a peculiar problem.

Old disk probably had a few corrupted files and copying was aborted (for the files) with "Invalid MsDOS function... try again skip" etc.

That's OK, and is natural.

But when there are parallel Move (or even copy) commands are executed, and if one command encounters this problem, all the commands- current files of the instants - are marked "bad" 

In fact I observed that even if I open "Properties" column of the "Bad" file (through explorer), a good file (not the one I was checking) even when only one copy command was going on, aborts as bad. After I close my window off the bad file, the copy continues from the then current file (having skipped a few while my property windows was open).

Thankfully it doesn't corrupt, since when I copy it later, it goes through.
