Very Computer

Our company just purchased an Indy and we love it.  We did not get a
CD-ROM drive with it but we would like to use a surplus NEC 2x drive
that was purchased for and used on a Macintosh.  We would like to use it
on the INDY but we are having some trouble with it.  The drive is a NEC
Model CDR-210 in an external case that has two 50 pin centronics SCSI
connectors and RCA out jacks.  We connected the NEC drive (scsi ID#3) to
the Indy with a Belkin 4' micro50 to Centronics 50 cable.  An Archive
DDS-2 DAT drive (scsi ID #4.  It is from APS Technologies and works
beautifully if we leave the CD-ROM drive off) is connected to the CD-ROM
drive via a standard cent. 50 to cent. 50 cable.  When we start the
system up we get the following message:

sc0,3,0: cmd=0x12 Unexpected info phase 47, state 40.  Resetting SCSI
bus sc0,3: SCSI parity error

SCSI device/cable diagnostic *FAILED*

I know it is not the Belkin cable because I use the same cable with the
Archive DAT drive and it works perfectly.  I suppose it could be the 50
to 50 cable between the CD-ROM and DAT but I did try two different 2'
cables (both were from the same manufacturer though).  The DAT drive
work fine in all instances.  I suspect it is a problem with the CD-ROM
drive.  Any suggestions are appreciated.

TIA!

Despite your saying that cable this works on a DAT, this is almost
certainly a cabling problem.  There is a chance it's a termination
problem (too many, too few, not active).

I have heard of more problems on NEC drives than I would have
expected, and one customer told me that NEC support insisted that
his particular model CD-ROM drive did not support 512 byte logical
block size, which means it can't be used for efs filesystems or
installing software.

I have also tried to connect NEC drives with no success, but the Toshiba
3401B works and can be found for under $200.00.

Could someone please illuminate me as to whether or not I am correct?

Thanks.

Not really. On Indigos (perhaps Indigo^2's as well?) the three internal
sled slots automatically configure devices in them to assume ID's 1, 2, or
3 if the devices do not override this choice. This does not mean that
those ID's cannot be used by other devices, only that one needs to watch
out for ID conflicts.

This is how we got our NEC 4X to work:

Insert a CD-ROM into the device. Do an ls on the /CDROM directory...note
that there is nothing there. Launch 'cdplayer' then quit immediately. Do
another 'ls' and voila...there it is.

Don't ask me why this works.
