You should have something like this :
hda: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(33)
You could try doing: dmesg | grep hda
or hdb / hdc/ hdd
.. Whichever connector you plugged it on and wether you set it master / slave.. So let's take mine for example. Which is plugged into my 1st IDE connector on motherboard. (the only one) and is set to Master. So linux made it hda.
so dmesg | grep hda results in:
ide0: BM-DMA at 0xf400-0xf407, BIOS settings: hda
MA, hdb
MA
hda: BENQ DVD LS DW1655, ATAPI CD/DVD-ROM drive
hda: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(33)
Hope this helps you
