fdisk oddities

Mon Jan 24 12:07:19 EST 2000

There is a bug in version 1.21 of the firmware in the calculation of the
geometry which effects the 72MB version. You should use the 1.22 tools +
firmware. The version is still not available on our web site, I will find
out when it is due to be public. 

I don't want to send the zip file to the list and overload everybody, Until
it's made public anyone who needs the new version please send me an email.

To use it :

Just run in DOS (sorry we don't have any Linux version of the tools yet)
dupdate /win=XXXX /s:doc122.exb
where XXXX is the address of your DOC

I get this on hard drives. They make up the geometry on boot, and I believe 
that they only read it from the partition table if they're _really_ confused

and can't work out what it ought to be.

If you _really_ want to do it, you can alter the NFTL code so that you can 
tell it what the geometry should be - just like you can tell the kernel on
its 
command line. But it shouldn't really help. If there are problems with the 
72 Mb device, they're not going to go away if you tell it the physical 
geometry is different - it'll still use all the flash anyway.
