After using old version of ZU (from 2009) on another PC, I get this error: "ERR:51E0EB14010104 CMD:0000000000E0EC NO DRQ!"

Can someone help me to unlock WD5000AVDS? I tried with zu.exe and z!.exe but it only shows only "ELAPSED 00:01.. 00:02... 00:03" and nothing happens. When I press enter, it shows "UNLOCK NOT DONE". The drive is from tv recorder. I suppose nobody will help me for free.. I can pay ...
