Applying scan_ffs output to disklabel?

Hi,

I'm in the process of recovering my drive (fat fingered dd and blew away the partitions). I've obtained the following output from scan_ffs but not sure how to apply this to recreate the disklabel. Running disklabel -R with this output doesn't seem to work.

fuguita# scan_ffs -lv sd2c
block 128673234 id a86900, 1d53400 size 30225408
block 150903347 id 8,0 size 76481934

block 1338443597 id 502b55c2,800e9b02 size 1130083924
block 1638543507 id abbbeaf9, b4ab0641 size 472173501
scan_ffs:_read: Invalid argument


Any recommendations on how I can at least rebuild the partition map and mount my partitions?

Thanks in advance!
