"Error processing drive sda"

[ärkefiende]

Hi folks,

wanted to install the new Fedora 11. I´m using the full installer (i386).
After choosing the keyboard layout, Anaconda searches for drives and gets this error:

Error processing drive sda.
Maybe it needs to be reinitialized. YOU WILL LOSE
ALL DATA ON THIS DRIVE.

I really don´t want to format my drive, so why does he get this error and how to correct that (without formatting).

I´m using this sd with multiple OS´s. Here´s my drive layout:
