Minnich <[EMAIL PROTECTED]> Subject: Re: file system error Thanks for your reply. I tried as your suggest. dd if=/dev/zero of=/dev/hda bs=1024 count=10000 ~ 100000 Segmentation fault's are occured in random by count. and then, turn off the UDMA feature by hdparm option. But, I can see same symptom. In this time, I tried to attach SCSI & IEEE1394 SBP-2 devices. case1. Adaptec 2930 SCSI adapter + 8GB Seagate SCSI HDD case2. IEEE1394 Interface card + external IEEE1394 HDD both cases show the same problem. Now, I think it's not a DMA problem. I'm in the maze. hmmmm......
