No help anyone?  Did I buy a taboo drive?  

nick@...uxamd:nick$ /usr/sbin/hdparm -i /dev/hdd

/dev/hdd:

 Model=TSSTcorp CDDVDW SH-S202J, FwRev=SB00, 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:383,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
 Drive conforms to: unknown:

 * signifies the current active mode


Any help to get this fixed (by me) would be welcome.  I cannot find any 
information on why this happens (or rather why the 'drive side') refuses to 
see 80-wire ide cable.

Thanks,

Nick
