[rtl] Flash disk probs

[James Cassidy <jcassidy@nova.genesoft.com>]

I can't get an IDE flash disk to work with Linux (RTLinux)...

I've finally got all the software working very well for 
our RTLinux embedded instrument.  Thanks RTLinux & the RTLinux 
group!

It's using RTLinux for the hard real time control + java
for all the non-real time stuff (networking, etc).

Now I'm having some problems with the last step.  I'm 
trying to embed RTLinux into the instrument using an
Advantech 8M IDE flash disk.  But I'm having little
success.

I've got a real IDE drive on hda and the flash disk
on hdb to get things copied across and set up.  But 
Linux doesn't want to mount the flash disk.

If I do a 'fdisk /dev/hdb', I get the message:

  Unable to open /dev/hdb

I can't mount it either.

To make certain the flash disk and cable work correctly,
I've fdisk'ed it from DOS and formatted it with DOS.  It
boots DOS correctly.  

But when I go back to Linux and try to mount it to see 
if it's possible with a 'mount /dev/hdb1 /mnt -t msdos',
I get the message:

  mount: /dev/hdb1 is not a valid block device

The flash disk has two chips on it labeled 'SanDisk'.
Does this type of flash disk not work with Linux?
Am I doing something bogus?

As always, any help would be greatly appreciated!

Regards,
Jim.
