I'm experiencing a weird (I think) behaviour when I first try to mount my
zip drive. First, some releveant data.

SCSI Card is a Buslogic 946c PCI card. Zip is SCSI 5, the only SCSI device
in the chain. 

In the kernel I have compiled:

controller      scbus0  #base SCSI code
device          sd0     #SCSI disk
disk            sd0
options         SCSI_REPORT_GEOMETRY
controller      bt0     at isa? port "IO_BT0" bio irq ? vector bt_isa_intr

In the fstab I have:

/dev/sd0s1e             /zip            ufs     rw,noauto       0       0

So the first time I try and mount the zip drive (using mount /zip), I get
the following stuff:

dirac# Jul 10 19:25:57 dirac /kernel: sd0(bt0:5:0): UNIT ATTENTION
asc:28,0
Jul 10 19:25:57 dirac /kernel: sd0(bt0:5:0): UNIT ATTENTION asc:28,0
Jul 10 19:25:57 dirac /kernel: sd0(bt0:5:0):  Not ready to ready
transition, medium may have changed

transition, medium may have changed

fictitious geometry

However the mount is successful after all of this stuff. Subsequent
umounts and mounts work without problems. If I eject the disk, then
re-insert it and try a mount I get that stuff again. Is this normal
because it's removable media, or am I missing something?
