phillips ide dvd drive, seek problems and weird hangs
 

I'm seeing weird seeks errors and then hangs using my ide cd/dvd drive. When I play a music cd using xmms, I sometimes get a seek error, then the cd plays, but xmms and any programme trying to access the drive (e.g. cdstop, eject, xmms, ide_info, etc) lock up. It seems to reset the the device, but then I can't do a thing and I can't talk to it. I can't eject the drive. The only thing I can do is reboot, which is a real PITA. If I use a pin on the hardware eject, the tray pops out but the disc just keeps on spinning.

Anyone have any ideas and fixes or workarounds?

cheers
