Thanks for the quick response. I myself suspected also strongly that the
higher speed of SATA compared with ATA somehow causes the problem. I did some
drive write speed tests - the SATA drive appeared almost twice as fast as my
IDE ATAs.
But back to solving the problem. I checked again the BIOS options for drive
control. It appears quite certain that disabling the HDD S.M.A.R.T has
removed the problem. After disabling it I've done so far numerous large file
copy actions between SATA and ATA drives without tilting the PC. And the
strange thing is that the ATAs now appear actually 10 % faster than before!
So HDD S.M.A.R.T. is not so smart.
