Even dodgier than waiting to quote a message from a digest that hasn't
arrived yet is hand-indenting a paste from pipermail :) but I'll hang
this off your thread, thanks Bruce ..

Although it's a brand new disk, quoting Chris' original message after

Hmm, should we bet against a gentoo install using GPT these days?
Finding out about the actual disk layout in gpt(8), gpart(8) etc proving
fruitless and finding nothing in Handbook, FAQ or wiki, I resorted to
http://en.wikipedia.org/wiki/GUID_Partition_Table for hopefully correct
information. I hadn't even known that sectors 1-33 were used for the
GPT (making Mike's zeroing of sector 1 sensible even on sliced disks),
nor that the last 33 sectors were for its backup table, thanks. So:
dd if=/dev/zero of=/dev/da4 skip=N
where N is the known total number of sectors minus 34, should do it?
If not, we can't rule out Mike's concerns about BIOS incompatibility
or such, but this sure sounds like the next thing Chris should try.
