Hi Nadya
Yes the key would be +/-16 chars. However, getting the harddisk serial number is a standard API call. Someone else has already given the code in another thread. The key could also be shortened in various ways. I just thought it was quite easy and removes the need to check the table (any table) for duplicates.
