I wish I'd read this thread last week.. I've been beating my head against this problem all weekend. I picked up a cheap 3114 card, and found that when I created a filesystem with it on a 250GB disk, it got massive corruption very quickly. My experience echos most the other peoples in this thread, but here's a few data points I've been able to figure out.. I ran badblocks -v -w -s on the disk, and after running for nearly 24 hours, it reported a huge number of blocks failing at the upper part of the disk. I created a partition in this bad area to speed up testing.. Device Boot Start End Blocks Id System /dev/sde1 1 30000 240974968+ 83 Linux /dev/sde2 30001 30200 1606500 83 Linux /dev/sde3 30201 30401 1614532+ 83 Linux Rerunning badblocks on /dev/sde2 consistently fails when it gets to the reading back 0x00 stage. (Somehow it passes reading back 0xff, 0xaa and 0x55) I was beginning to suspect the disk may be bad, but when I moved it to a box with Intel sata, the badblocks run on that same partition succeeds with no problems at all. Given the corruption happens at high block numbers, I'm wondering if maybe there's some kind of wraparound bug happening here. (Though why only the 0x00 pattern fails would still be a mystery). After reading about the firmware update fixing it, I thought I'd give that a shot. This was pretty much complete fail. The DOS utility for flashing claims I'm running BIOS 5.0.39, which looking at http://www.siliconimage.com/support/searchresults.aspx?pid=28&cat=15 is quite ancient. So I tried the newer ones. Same experience with both 5.4.0.3, and 5.0.73 "BIOS version in the input file is not a newer version" Forcing it to write anyway gets..
