I was given an iHAS324 DVD/CD writer that I installed into my older Mac Pro (10.6.8). I was under the impression that it would work using an IDE to SATA adapter. It reads and plays discs fine but freezes up when I try to burn. Additionally, it whirs every few minutes (a quick, double spin?) even when I'm not using it. A friend told me that I might need to flash the drive but I'm not experienced in this and don't know where to even start. Is there something that I might do to get it working properly? If not, does anyone have a recommendation for a good DVD drive? Thanks in advance for any help that you might be able to provide me with.
