I use an assembled desktop with two 2 Tb Western Digital hard drives,Intel
Core i3 3.2Ghz processor and 8 Gb RAM running Windows 7 Ultimate 64 bit;
DVD-RW: LITE-ON iHAS-124
Antivirus: Avira Free Antivirus;
Firewall: Zonealarm Free Firewall
DVD-RW drive is not able to write to DVD-RWs. Usually the writer hangs. Trying to open DVD-RWs by rightclick in My Computer yields hourglass symbol. DVD-RW writer was changed with another copy of the same model without improvement. Brand new DVD-RW showed same result. CD-RWs read and write properly.
Equally poor result with burning sofware Nero 7 Essentials, Ashampoo, Deep Burner and Windows burning software.
