Excellent, I'm glad everything worked out. It may have been a leftover secondary GPT. From g_part_gpt.c: /* No primary? Check that there's a secondary. */ buf = g_read_data(cp, pp->mediasize - pp->sectorsize, pp->sectorsize, &error); This would seem to suggest that the secondary GPT is stored in the last block of the drive. Zeroing that block would probably have worked too. On Thu, Jun 24, 2010 at 12:41 PM, Mark Costlow <cheeks@swcp.com> wrote: > Nick, that worked!
