I started having a problem with one of my DVD drives, not sure what set it off, I am without ADSL atm and thought it might have been when I put in a PCI dial-up modem, since after I put that in one of my TV cards "Failed to start", but that fixed itself after another reboot.
What turned out to be wrong was one of my drives (an LG) was in PIO mode. This is on the primary channel and was the slave. Being in this mode sucks, not only did it take an hour to burn a DVD9, but it savages system performance. When watching video it just stutters like mad.
So I whipped out the drives and put my old pioneer on slave and the LG as master, job done it seemed, both in DMA mode. Until last night, I put in a DVDRW and set it off storing some stuff while I went for dinner. When I came back, it was just starting the verify stage and the TV had come on to record the daily show and was stuttering again.... The record was fine, just the playing seems wasted. Anyway I saw in task manager that nothing was registering much CPU use, but one core was loaded. So I looked in proc explorer and it said this near 50% cpu was hardware interrupts!!.
Checking in device manger, the drive is back in PIO mode and its setting was "PIO mode only". I then checked my uptime which was 5 1/2 days, sometime friday, but on Monday I'd burnt a disc and then watched a DVD and it performed fine then. So it must have slipped into PIO mode while on. While watching the DVD it locked up MPC near the end as there was some dirt on the disc, after cleaning it MPC was stuttery so I resorted to watching the last 4 minutes in PowerDVD, so maybe this is when it went bad.
I put the setting back to "DMA when available" and restarted, no good, tried a full power cycle, no good. It's in DMA when booting because my boot screen tells me so, but its only the LG which is doing this, although I'm not using the pioneer much as it's just about worn out.
Any advice?
