I was having a few problems with 2 new Sony DRU-800A drives. Both drives are in the same computer. It is on a MSI Neo2 Platnium motherboard, AMD Athlon XP 64 3200+, 1gb OCZ Platinum Rev 2 RAM, WindowsXP Pro.
The first problem isn’t directly realted to the drives. When I check the log from Nero, it lists all my drives (DVDRW, and HDDs) with “DMA: OFF”. In windows system manager, all of the channels have DMA enabled, and say either 133 or 66 (the two DVD writers are at 66). In the bios, DMA is also enabled.
The second drive (which I have moved around to different controllers Primary/Slave, Secondary/Master, and Secondary/Slave) will often get “Power Calibration Failed” messesages after taking one or two minutes at the Lead-In when burning. If it gets past that, at 8X it almost always fails. It also has trouble reading RW disks that it previously wrote (when one is in, dvdinfopro, nero say there is no media in the drive)
Another weird thing is both of these drives make a faint clicking noise. It’s not very loud, but still noticable. I think it would be odd that both drives would have something wrong with them.
Is there something you have to do to change a drive? Or can you just pull out the old ones and stick the new ones in? I have a spare hard drive I’m going to slap in the box and do a fresh install of Windows on to see what happens.
Any help (especially with the DMA thing) would be much appriciated
