Yup..definitley weird.
Have you added anything to the IDE chain?
Some CF cards like to be the only device on the cable. :pissed:
I had fun and games getting my CF to partition, and that was under 3.1 ( my OS3.9 CD has gone walkies, I found the case, but as is always the way, it`s empty !)
Whatever I tried, I couldn`t get the partitions to show up ready for formatting. Installed a filesystem, partitioned the CF card, saved the changes and rebooted..still nothing.
In the end I just thought "what haven`t I pressed ?".. Lowlevel format. I thought using that went out with the ark, but it did the trick.
