Hi,
I have tried to follow Backtrack 5 – Bootable USB Thumb Drive with “Full” Disk Encryption from infosec ramblings but after making partitions I can't write the new table as I get following:..the partition table failed with error 22
partprobe isn't working. I tried to remove usb stick before trying to write new partition table and so on.. but nothing seem to work.

Any advice how to do this installation?

Thank you
