how to use cdrecord

[Aiza]

Been using burn for blanking and burning iso files to cd.
Now i have need to use mkisofs so though I would try cdrecord
to blank cd and write iso to cd.

dmesg -a |grep acd gives this
acd0: CDRW <Hewlett-Packard CD-Writer Plus 9500/1.0e> at ata1-master UMDA33

tried cdrecord -v speed=2 dev=acd0 blank=fast
gives this error "Open by devname not supported on this OS.

What device am i to use?
