Dear Soren, Following is answers on your (and other folks) questions concerning hang mentioned above. 1. Yes I have powersaving enabled, but as long as disk being accessed it should not to go sleep. 2. Don't mind why I need to zeroing my disk - leave it as it is. 3. Swapping on this partition was disabled (really it is not swap space it just empty partition). 4. Reading out of this partition working perfectly (dd if=/dev/... of=/dev/null bs=1024k). 5. Hang doesn't depend on partition type - I observed it on 165 (FreeBSD) and on 6 (FAT) partitions. 6. As long I can approximate - system hangs somewhere at the end of partition (I used reading time to approximate it).
