I've been using a flash disk (128Mb) with kernel 2.4.x (in Suse 9.0) for 
months, until I replaced it with a bigger cpacity one and which also has 
USB 2.0 capability - and then I couldn't get a rise out of the darn 
thing. However, I finally got it to work with kernel 2.4.x, as well as 
the 2.6.5-7 kernel with some help from someone in the UK.

Check the following after you plug it in:

* what is displayed when you use 'fdisk -l'? The flash disk should 
appear as sda and may then be split into 4 primary partitions (sda1 - 
sda4) with goobly-dook beginning/ending sectors (mine ended up having 
1.3Tb - yes Tb - of available space in the last partition (sda4) :-));

* is it formatted as a single primary partition as FAT16? You may need 
to do this using the partitioner in your Linux distro;

* if it ends up being seen correctly in fdsik (or cfdisk, which is 
better app to use) but it still won't appear on the desktop - even if 
the system beeps to indicate that it has been "recognised" - then the 
way to go is to insert an entry into fstab so that the icon appears on 
the Desktop on boot and you can easily mount it. The entry ought to look 
like this-

/dev/sda1 /<mountpoint>/sda1   auto   sync,noauto,user,exec  0 0

in my case <mountpoint> is /media so the entry here is /media/sda1 .


All Scottish food is based on a dare.
