SUMMARY: Ultra 5 solaris 9 IDE 160GB

Sunmanagers,

This is a followup digest of the responses to my original post. Thanks to all. I had the same
problem after moving the 160GB drive to my 3 year old Windows PC with a promise Ultra66 IDE
contoller which also has the latest PROM update. I was limited to 137GB.

Thanks again, Wade

P.S. Yes, I checked the archives before I posted!
