Or just sitting in infinite > loop? Transfering your system to a new disk aside - THAT is the REALLY STRANGE question here! The fsck program does not simply hang in infinite loops. This indicates a severe problem probably with your hardware, and that has not neccessarily to be the disk. You should really try step by step, in _small_ steps. Can you boot the system from a live CD? If yes, do that. Then check each file system separately: # fsck -yfv /dev/ad4s1a # fsck -yfv /dev/ad4s1d # fsck -yfv /dev/ad4s1e # fsck -yfv /dev/ad4s1f # fsck -yfv /dev/ad4s1g and so on. If it helps, try that with ACPI disabled again. There is no real use in trying to copy a possibly damaged file system to a new disk. Before you copy, make sure they're all consistent. By the way, in addition to the mentioned ways to copy an OS and and data, there's still the "old school" toolset that can be used: First initialize the disks (for example with gpart, use MBR only if you need to, otherwise go with GPT). Then format the new partitions (newfs) and install the boot blocks (or boot partition for GPT). Additionally make sure to apply labels to the file systems (so you don't have to mess with device names in the future). Finally, use ye olden dump and restore. Here's an example. Let's assume /dev/ad4 is your designated new disk, /dev/ad6 your current disk (failing, will be abandoned). The target disk has been partitioned with GPT, the file systems have been initialized already. The source disk is _not_ mounted. # mount /dev/ad4p2 /mnt # cd /mnt # dump -0 -L -a -u -f - /dev/ad6s1a | restore -r -f - # mount /dev/ad4p3 /mnt/tmp # cd /mnt/tmp # dump -0 -L -a -u -f - /dev/ad6s1d | restore -r -f - # mount /dev/ad4p4 /mnt/var # cd /mnt/var # dump -0 -L -a -u -f - /dev/ad6s1e | restore -r -f - # mount /dev/ad4p5 /mnt/usr # cd /mnt/usr # dump -0 -L -a -u -f - /dev/ad6s1f | restore -r -f - # mount /dev/ad4p6 /mnt/home # cd /mnt/home # dump -0 -L -a -u -f - /dev/ad6s1g | restore -r -f - # cd / # umount /mnt In this example, /mnt will be the subtree that later on becomes /. Of course you have to check which things apply to _your_ setup! Note that you can also do that easily from a live CD. Note that for this task, only the destination media has to be mounted, the source media usually not. By using this approach, you can make sure that all file attributes get transferred correctly.
