Cant' mount usb drive, /dev/sda1 not showing up

Hi, I'm trying to mount a usb drive but the path /dev/sda1 does not show up under /dev when I plug in the usb device.

In fact I see no differences under /dev before and after I plugin my usb drive.

Any ideas why the system is not recognizing the usb drive and how to fix?

This is on a Solaris 10 OS.

thanks,

I am not into Solaris but I know it from my Debian box. Maybe it helps so here you go:

I just had to make sure the USB kernel modules / drivers are there and then I just mount it to some mountpoint. It is not like that when I plug in the stick that there will be automatically be a device file created unter /dev. The needed device files are already there.

I just go on with

mount /dev/sda1 /mnt/usb

When plugged in, I get in /proc/bus/usb/devices following additional entry:

T:  Bus=04 Lev=01 Prnt=01 Port=07 Cnt=01 Dev#=  3 Spd=480 MxCh= 0

The other entries are about the controller etc.

Make sure that sda1 is not a partition or something of your other SCSI devices.

Is this a brand new USB drive?

sorry for such a delayed response...

The USB drive is not new, it is the first time i've plugged it into this machine. I plugged into a Linux machine running and it was recognized right away.

When i do an rmformat the USB drive does not show up.

any other suggestions?

thanks,
