its an ide drive. Why everything is coming up sdx instead of hdx I have no clue. I checked the dvd link is /dev and it points to scd0 if that helps.
heres some output from hdparm is it helps
# hdparm -i /dev/scd0
/dev/scd0:
Model=DVDRW USB1008UI , FwRev=VER 0159, SerialNo=
Config={ Fixed Removeable DTR<=5Mbs DTR>10Mbs nonMagnetic }
RawCHS=0/0/0, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=0kB, MaxMultSect=0
(maybe): CurCHS=0/0/0, CurSects=0, LBA=yes, LBAsects=0
IORDY=yes, tPIO={min:227,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2
UDMA modes: udma0 udma1 *udma2 udma3 udma4
AdvancedPM=no
* signifies the current active mode
# /sbin/hdparm -d1 /dev/dvd
/dev/dvd:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Inappropriate ioctl for device
Any kind users out their in forum land that can give me a hand?
EDIT
I tried # hdparm -I /dev/dvd
/dev/dvd:
HDIO_DRIVE_CMD(identify) failed: Input/output error
so I might have some deepet issue
