Lost RW abilities

For some reason my DVD-RW lost all abilities to burn discs of all sorts, it doesnt even show up on a cdrecord -scanbus. If I remove the SCSI emulation from Lilo I can mount and play both DVDs and CDs fine. Is there something that I am missing? Maybe a module I need to load?

hdparm -I /dev/hdb


ATAPI CD-ROM, with removable media
Model Number: _NEC DVD_RW ND-2500A
Serial Number:
Firmware Revision: 1.06
Likely used CD-ROM ATAPI-1
DRQ response: 3ms.
Packet size: 12 bytes
LBA, IORDY(cannot be disabled)
DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2
Cycle time: min=120ns recommended=120ns
PIO: pio0 pio1 pio2 pio3 pio4
Cycle time: no flow control=120ns IORDY flow control=120ns

what kernel are you using? if you're on 2.4 then you DO need the ide-scsi option, if you're on 2.6 then you don't. this might be a nice time to think about upgrading to 2.6.10 or similar, if you are still on 2.4, as you'll get much better support and faster write speeds.

I am very scared about upgrading to a newer Kernel, I have alot of devices living in Harmony right now (Freevo box using a Matrox card [DirectFB] with an LCD [serial to usb driver ftdi_sio]). They took me such a long time to finally get working all together in the same box that I dont want to lose them all.

Well, I found the problem. For some reason ide-scsi wasnt being loaded at boot time. I found it on the blacklist and also added it to the /etc/rc.d/rc.modules and everything seems to be running fine.
