Hi, # /dev/da1s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] c: 71087562 0 unused 0 0 # "raw" part, don't= edit e: 71087562 0 4.2BSD 2048 16384 28552 Errrr, should the offset of first partition start from offset 16? evil sysinstall... If so, then I dont think I have much to do except backup, fix the offset, create a new gconcat, and restore? Thanks, Rong-En Fan
