An image copy of the disk will tend to recover more than accessing the disk via the file system. I haven't run across the failure mode where accessing a certain magic block causes the disk to die and require a power cycle, but in that case what I'd probably do is enhance the dd_rescue program to take a list of block numbers which it should skip over.... This will require some programming, but it's probably the best way to recover the most amount of data. (Oh, and afterwards someone should send the changes back to Kurt Garloff, since it would be a very useful enhancement to dd_rescue.) - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
