Eek - I had to resort to Win2k as cdrecord didn't like my SCSI burner -
grrr!

I got myself further confused as somebody offered me a SCSI burner the
other day which also has a block size jumper on the back - hence I
wasn't sure if there were special burners needed for 512 byte block CDs.

shush! :-) Actually I should get the machine on the LAN then it
wouldn't matter...

I'm drowing in a sea of different SCSI connectors at the moment - the
Indigo has the 50 pin centronics style connector, the Indy has a HD50
connector, the desktop PC has the HD68 connector, then I have single
external 5.25" boxes that have HD68 on them, single 5.25" boxes that
have HD50 on them, and dual 5.25" boxes that have 50 pin centronics on
them. Some of the HD68 boxes have 50 pin IDC internally, others have
SCA... (and don't even get me started on 3.5" boxes)

Ideally I'd like to get both my DAT drive and a CDROM capable of 512
byte blocks into a dual external case so I can easily shift them around
between machines, whilst not wasting precious SCSI bus length.

Trying to do that with the bits and the cables that I have available is
making my brain hurt :-) And unless the Indigo's external bus is faulty,
my 50-50 pin centronics cable has died - the Indigo recognises external
devices hooked up via it but barfs when trying to access them at a
reasonable speed. It's not a termination issue, unless there's a magic
"terminate external bus" switch buried inside the Indigo somewhere :-)

*sigh*

cheers,

Jules
