[ale] Not valid block device error

[Sunmeet Saluja]

Hi Dow-

This is an Apacer Handy Steno Model TN202 Drive with a write protection 
switch.  And, this works perfectly fine with the Win2k based PC. I've 
tried switching the write protection in both positions, but same result.

The fact that its working fine with the Win based PC and not working on 
my RH Linux WS is what has been bothering me all this time.  I'm going 
to go ahead try to find and call the vendor to see if they can be of any 
help, as this drive is suppose to work on Linux with 2.4.0 or above kernels.

Thanks for looking into the matter for me.

Regds,
Sunny
