Jaz drive on an adaptec 2940AU

[gordon.jones23 at ntlworld.com]

Hi,
I'm a newbie to linux i'm affraid. I've had my redhat 7.2 system 
going for 
a month or so now and have been gradually learning how to use linux 
and set up a home network. I've now managed to get samba running as 
a domain controller for several windows machines, providing home 
directories etc. My thoughts have now turned to backup. I've got hold 
of a 
1gb external jaz drive and an adaptec 2940AU scsi card. Everything 
appeared to be going ok - redhat detected the card when i booted the 
system and offered to configure it (I'm not sure it has been entirely 
successful). I downloaded iomegaware for linux, and I now have an 
icon 
on the desktop to mount the drive, except it won't mount.

I get the error "mount: /dev/sda4 is not a valid block device"

>From reading round online I've found serveral commands that provide 
useful info, but I'm not sure how to procede. I'll list all I can in 
the hope 
someone can make sense of it and help me!

executing "cat /proc/scsi/scsi"
produces

(no sign of the adaptec card!)

executing "dmesg" produces

(the card seems to show up several times here!)

If anyone can throw any light on this I'd be very grateful
