Thanks,

I tried Testdisk. After changing the geometry to the real values, Testdisk told me a diskspace of 8 GB instead of 40 GB. Therefore I refused to write the new partition table.

Meanwhile I tried to change geometry with linux fdisk. But the error message was, that fdisk can not change the geometry till it is in use. The problem is, I have in this notebook only one harddisk and one CD-ROM. If I boot Knoppix from CD harddisk is in use too.

XP and Knoppix from HD are running at the moment without error messages related to this issue.

I hope this wouldn't change.
