the jumper- I removed
it and the full 400 GB are accessible now.
Thanks for helping me look.
@bill: that document is not very clear to me. Just what does "Lower 32GB", "Upper 32GB" or "With capacity limitation in upper 32GB" mean? I have 3 Samsung SATA drives, but this is the first time I've had to decipher their jumpers on a PATA drive.
The drive came with one jumper, set for "Master in lower 32GB (capacity < 32 GB)" and I initially just moved it over by one, with these disastrous results. I guess I'll have another look via Google or do some trial and error before finishing this off.
Anyway- the main problem is solved- bring on the next one....
Edit: I just found the Installation guide
and I'm home free (page 3 says it all).
