In order for the files to go 0 byte the following two scenarios must occur:
1. The current directory as seen with pwd command must be SYS:_NETWARE.
2. An invalid target directory is used
So if the target directory does not exists it will copy the files to the current working directory. If that is _NETWARE, then all files will go 0 byte. Hence corrupting the database. If the current working directory is not SYS:_NETWARE then the files will be copied there.
I would suggest not using this utility. If you are going to use it, then do not use the /q switch.
