What actually happened was the following. I was copying a large amount of data (50GB) form one disk to another. Halfway I wanted to cancel the operation and clicked cancel (I used konqueror to copy the data). The copying was canceled but that when the I/O errors start appearing and I needed to reboot. I do have quite a long cable attached (about 50cm sata cable) but copying was just fine so I guess this wasn't the issue. I also used the disk quite a lot on FC4 and only have this issue since I'm on FC5 (perhaps a driver issue ?!). regards, Marcel
