I made my own patch (following Mark's example) but also added that printk in that function.

Now that we have found the ata_op code of 0x35, what does this mean? Is it generated from a bad FUA/unsupported command from the kernel/SATA driver?

In /usr/src/linux/include/linux/ata.h:

  ATA_CMD_WRITE_EXT = 0x35,

Perhaps these drives do not support this command or do not support it properly?

Any idea, Jeff/Alan?
