I've changed the PSU, after thar the bios doesnt recognize hdd (it is some ibm IDE model), but dvd rw does. I tried another 5 IDE HDDs but only one has been recognized, just in master mode. I also tried many cables, and another psu, bios reset.... All those 6 hdds another computer/bios recognized with no problems. The motherboard is Siemens D1495.
Any idea?
