It's hard to imagine so= mething=20 is wrong with the hardware in this case, though: * Both drives are affected, a Samsung and a Seagate. We can rule out th= e=20 drives. * Both drives worked in AHCI mode with the same cables and power supply= with=20 the ICH9 based Gigabyte board: We can rule out the drives themselves ag= ain and=20 also the cables. * Different SATA cables did not help. We can rule out the cables again. * Unplugging everything in the machine except the drive with the root=20 partition and the video card did not help: We can rule out the power su= pply (a=20 high quality Tagan 400W model, not some OEM junk) with a near 100%=20 probability, I suppose. So, all that's left is the mainboard. But on this same machine, AHCI in= =20 Microsoft Windows XP works without any problem whatsoever. I know the o= ld=20 Linux-stresses-your-hardware-more-than-Windows tale, but I haven't seen= proof=20 of that for 10 years now. This finally seems to rule out the mainboard = and at=20 least to me it appears the software side is all that is left. What can I do to diagnose this further short of buying an additional po= wer=20 supply and mainboard? Volker
