A new controller is NOT needed, you only need the 48-bit
LBA kernel patch (or a kerner that has 48-bit LBA already).
Marco, you wasted your 78 EUR. With the patch, the 160GB
disk works full size on most newer controllers.

I ´haven´t install such a patch but I have full capacity (153GB in
KdiskFree) with Kernel 2.4.10
Do I need the patch or a newer kernel?

I also tried a very old Promise Ultra66 controller.
While the correct disk size was detected and could be
used in full, I had occasional data errors using the
newer Ultra133 120GB and 160GB disks on the Ultra66
controller.
So I strongly recommend to run a disk test that writes
and verifies every byte and uses different contents.
badblocks was not able to find these errors, so I wrote
my own test which did find the problem.

Where I can find such a disk test?

Carsten.
