Thanks to the answers and hints from:
Michael Horton, Ryan Krenzischek, Julio Carrasco, Ric Anderson, Tim Chipman,


"IIRC, the Blade-100 still uses an ATA-4 controller which
maxs out somewhere around 127GB at the hardware level." (Ric Anderson)

This seems to be the same limit as for a Ultra 5 according to this summary:

May I suggest that this fact is being added to this list's  FAQ:
Subject: 5.11) * How do I use an EIDE/ATA disk larger than 8GB?

| At least 127.5 GB for a 160 GB disk :^(
|
