`camcontrol da? stop` seemed to do the trick before (5.2.1-R, AFAIR),
but now I'm not sure (looks like it doesn't)
sorry, I meant to say that `camcontrol da? stop` does not power down
the device anymore; nonetheless, it is probably safe to disconnect it
No, camcontrol does not support this over USB. Windows XP demonstrates
it is technically possible, and I do not believe it is fully safe to
disconnect the drive (even when unmounted), as the drive then is not
able to park its heads, which it DOES do under XP.
So, we come back to the original question: how to send an
IRP_MN_REMOVE_DEVICE event?
Maybe this helps?
man camcontrol ? :
cmd Allows the user to send an arbitrary SCSI CDB to any
device.
The cmd function requires the -c argument to specify
the CDB.
Other arguments are optional, depending on the command
type.
The command and data specification syntax is documented in
cam_cdbparse(3). NOTE: If the CDB specified causes
data to
be transfered to or from the SCSI device in question, you
MUST specify either -i or -o.
-c cmd [args] This specifies the SCSI CDB. CDBs
may be
6, 10, 12 or 16 bytes.
-i len fmt This specifies the amount of data
to read,
and how it should be displayed. If the
format is `-', len bytes of data
will be
read from the device and written to
stan-
dard output.
-o len fmt [args] This specifies the amount of data to be
written to a device, and the data
that is
to be written. If the format is
`-', len
bytes of data will be read from
standard
input and written to the device.
