When attempting to copy a large file over to a FAT partition, I had these
errors pop up:
Nov 27 16:26:59 volatile /kernel: ata0-master: ad_timeout: lost disk contact - resetting
Nov 27 16:28:17 volatile /kernel: ata0: resetting devices .. WARNING: WAIT_READY active=ATA_ACTIVE_ATA
Nov 27 16:28:17 volatile /kernel: done

Nov 27 16:28:18 volatile /kernel: ata0-master: ad_timeout: lost disk contact - resetting

Nov 27 16:28:19 volatile /kernel: ata0-master: ad_timeout: lost disk contact - resetting
Nov 27 16:28:19 volatile /kernel: ata0: resetting devices .. done
The errors continue until the system either panicked and rebooted or just
plain rebooted, I was not at the console. However, the FAT volume was
corrupted along with the boot loader (grub) overwritten to some
extent. I'm not 100% sure if it was just the partition table or the entire
volume. Next, I cvsup'd and built new kernel+modules, and the same error
happened, but there was no reboot and a couple new error showed up:
Nov 27 18:24:33 volatile /kernel: ad0: HARD WRITE error blk# 1912525 status=51 error=10
This error occurred for several different blocks.
The two drives are identified as:
ad0: <ST32140A/08.08.04> ATA-? disk at ata0 as master
ad0: 2015MB (4127760 sectors), 4095 cyls, 16 heads, 63 S/T, 512 B/S
ad0: 16 secs/int, 0 depth queue, DMA
ad1: <WDC AC418000D/J78OA30K> ATA-4 disk at ata0 as slave
ad1: 17206MB (35239680 sectors), 34960 cyls, 16 heads, 63 S/T, 512 B/S
ad1: 16 secs/int, 31 depth queue, DMA
The motherboard is fairly old and does not support ATA/66 etc, and the
drive with the fat fs has been rock solid so I doubt it has suddenly gone
bad. I'd like to test this with DMA turned off, what flags will disable
that?
