I turned on SCSI debugging for this drive.  When I try to mount it,
this is what happens:

cd0(si0:6:0): command: 0x1b,0x0,0x0,0x0,0x1,0x0-[0 bytes]
cd0(si0:6:0): back in cmd()
cd0(si0:6:0): sc_err1,err = 0x1
code 0x70 valid 0x0 seg 0x0 key 0x2 ili 0x0 eom 0x0 fmark 0x0
info: 0x0 0x0 0x0 0x0 followed by 8 extra bytes
extra: 0x0 0x0 0x0 0x0 0x3a 0x0 0x0 0x0
cd0(si0:6:0): scsipi_interpret_sense returned 19

So, I'm sending a START_STOP command to start the thing, and the drive
is returning a sense key error, SKEY_NOT_READY.

I took the top off, and the motor never spins while this is happening,
so I may just have gotten a bad drive.  But, to exhaust all of the
possibilities:

- I noted that in scsipi_interpret_sense(), there's an option
  to SCSI_IGNORE_NOT_READY.  Could this apply to this drive?

- Maybe there's "something else" that needs to be sent to this
  drive to make it go?  What's the SSS_LOEJ bit do in the START_STOP
  command?

Thanks in advance,

Matt
