Recently, both the drives have been functioning slowly. When I write 16x-rated Verbatim DVD+R discs with EITHER, the writing starts at around 2.0x and slowly increases to maybe 7-8x by the time the disc is written. When reading DVD-ROMs, again, it starts at around 2.0x and very slowly increases to only 6.0x MAX. This did not used to happen, with either drive.
I have also noticed that the speeds of the 2 drives are "connected" - if I start reading discs in both drives at once, the speeds are exactly the same, increasing and decreasing - one had a read error once, and the other slowed down to the same speed - and if I pause one, the other drops to 0.0x.
This seems like quite a strange problem. I have tried uninstalling and reinstalling both drives, and the IDE channel - to no effect. Both devices are working properly according to Device Manager, and are using UDMA2, not PIO.
