looking good! when I run ubiquity, it lists the /dev/mapper partitions in the "Prepare disk space" > "Manual" > "Prepare Partitions" menu.

Can you leave this thread open a little longer? I will do a "Solution" post for others with new offsets. Is there a command you can run to scan the last 2000 sectors of your hard disk for the string "Promise Technology, Inc." ?

I did a post on the ataraid-list regarding this problem. Would you like to post the solution?

Thanks for the help! The damned thing actually works!!!
