[UFO Chicago] Dead DVD does dubious dance during desired duties

[Jesse Becker]

Since the subject doesn't really make sense (it's late, I'm
tired), here's a translation:

I have an IDE DVD installed in my desktop box at home.  It
doesn't work (anymore), and I'm wondering if it's a
hardware problem, or something else.  The drive *used* to
work, but I haven't needed to do anything with optical
media at home for months... (yay DSL).

The gory techinical details:
  * Kernel:  Linux 2.4.20 (gentoo)
  * System:  P-III 1GHz, 512MB ram
  * Using DevFS
  * hda: IC35L060AVER07-0, ATA DISK drive
  * hdc: SAMSUNG DVD-ROM SD-616, ATAPI CD/DVD-ROM drive
  * hdd: IOMEGA ZIP 100, ATA DISK drive

Symptoms:
  1) Can't mount CDROMs
  2) Can't play DVDs
  3) The device files in /dev are not created for the DVD
drive, but are present (and even correct!) for the hard
disk and zip drive.
  4) Symptoms are the same with, and without ide-scsi
emulation.
  5) IDE support is compiled directly into the kernel, all
SCSI stuff is a module.
  6) Certain operations that tickle the device (assuming
there's a 
  7) Lots of error messages.  These are typical (I've
snipped the many duplicates):

Mar 15 23:22:00 localhost hdc: irq timeout: status=0x58 {
DriveReady SeekComplete DataRequest }
Mar 15 23:22:00 localhost hdc: drive not ready for command
Mar 15 23:22:10 localhost hdc: drive not ready for command
Mar 15 23:22:10 localhost hdc: status timeout: status=0xd0
{ Busy }
Mar 15 23:22:10 localhost hdc: drive not ready for command
Mar 15 23:22:10 localhost hdc: ATAPI reset complete
Mar 15 23:22:20 localhost hdc: irq timeout: status=0x51 {
DriveReady SeekComplete Error }
Mar 15 23:22:20 localhost hdc: irq timeout: error=0x20
Mar 16 01:19:55 localhost hdc: bad special flag: 0x03 

Thoughts? (or hardware recommendations?)
