I installed Knoppix to the HD and now i cant use my cd-rw and dvd drives. The floppy drive wasnt working either but i was able to fix it, but i cannot get these to work. here are some of the tests i have run from reading other posts

Code:
dmesg | grep CD
gives me....

hdc: HL-DT-STDVD-ROM GDR8161B, ATAPI CD/DVD-ROM drive

Uniform CD-ROM driver Revision: 3.12
hdd: ATAPI 40X CD-ROM CD-R/RW drive, 2048kB Cache

Code:
dmesg | grep sc
