I think, in the long run, the `od' driver is a better candidate for
removable media drives, even if they are not strictly `optical'. They
share the same set of problems as MO drives.
If you wanna give it a try, you can add a hook to /sys/scsi/scsiconf.c
like this:
[existing entries:]
static struct scsidevs knowndevs[] =
{
/* od's must be probed before sd's since some of them identify as T_DIRECT */
#if NOD > 0
{
T_OPTICAL, T_OPTICAL, T_REMOV, "MATSHITA", "PD-1 LF-1000", "*",
"od", SC_MORE_LUS
},
{
T_DIRECT, T_OPTICAL, T_REMOV, "SONY", "SMO-*", "*",
"od", SC_MORE_LUS
},
^^^^
around here, put:
{
T_DIRECT, T_OPTICAL, T_REMOV, "IOMEGA", "XXX*", "*",
"od", SC_ONE_LUS
},
...with "XXX" being the beginning of your device model string (as you
can obtain from the probe message in /var/log/messages). This will
forcibly assign the IOMEGA drive to the `od' driver. Of course, you
need
device od0
in your config file. It should become device /dev/od0 etc. then.
Disclaimer: All this will only work for FreeBSD 2.2-something systems.
