alrighty then,,
how about this... the hot swap drive holders for the 3 extra drive slots in my PE2650 are plastic, with no screw holes. I assumed (incorrectly) that they were simple press fit and slide in...comparing to the other 2 drives, which have metal trays and are screwed in place, it was obvious that the new drives were not seating (about 3cm too short) and there was no connection to the system... bios wasn't recognizing them because they weren't attached to the machine. might as well have been sitting on my desk
fixed the trays so they seat properly and viola...I have a brand new raid 5 container
thx for your help
