I am trying to pull the data off of a failed hard drive, and knoppix hangs during boot. I've tried booting with the "knoppix noudev nodma" command, and it gets a little further, but hangs when it tries to scan the partitions. I've also tried connecting the drive after knoppix is done booting (it's a SATA drive), and it starts to try to configure, but then hangs. Any help would be much appreciated.
